Optimization of Pervious Concrete Mix Design used for Pervious Concrete Pavement The main aim of this research work is to optimize the mix design for the pervious concrete for the practical application on the field. The objective of this investigation is to study the cement aggregate proportion for properties of pervious concrete by producing various mix design. It has been found that 1:4, cement to aggregate gives better result as compare to other selected mixes. To further improve the workability on pervious concrete, investigation has been carried on chemical admixture used in pervious concrete. It is found that 0.9% chemical admixture dosage is sufficient for pervious concrete. Pervious concrete is produced with different size of aggregate. After various combination of aggregate size pervious concrete produced with single size aggregate (4.75 mm – 10 mm) having more compressive strength than other size of aggregate. For pervious concrete as the density increases compressive strength increases while permeability decreases. The paste flow test performed on different design mixes on pervious concrete. For the test mini slump cone has been used. According to literature given for the paste flow requirement for the pervious concrete is 280 mm. The range of the paste flow has been achieved by doing many trials. For further improvement in compressive strength VSI aggregates are used as a replacement with normal coarse aggregate. VSI aggregates is having lesser flakiness and elongation index values. VSI aggregates having rounded edges and provides proper bond between aggregate with cement. Pervious concrete with VSI aggregate increase the compressive strength around 25 to 30% respectively. For pervious concrete mixture compaction methodology is very important. Different compaction techniques has been adopted on selected mix design of pervious concrete. It includes hand compaction, vibration on vibrating table and compaction by marshal hammer, proctor hammer and Needle vibrator. Void content in pervious concrete ranges in between 15% to 20%. It is observed that compaction by vibrating table gives 20% void content as compare to other techniques. The main properties studied are compressive strength, density, permeability, and void ratio. For the measurement of permeability test set up is developed. The falling head test method was used to find out permeability coefficient. During experimental investigation results shows that pervious concrete having density around 1800 kg/m3 to 2250 kg/m3, compressive strength between 8 to 20 MPa ,permeability between 11 to 21 mm/sec and Void Content 15 to 25%. After consideration all aspects a final mix design has been established based on investigation. July 2017
Comparative study of mechanical and durabilities properties of concrete using waste foundry sand Foundry industries are produce useful materials. However along with this material some by-products are also produced in huge amount. The dumping of this by-product material is major issue of the industries. Waste foundry sand is major by-product of metal casting industry and successfully used as a land filling material for many years. But use of waste foundry sand for land filling is becoming a problem, due to rapid increase in disposal cost. An effort to use the waste foundry sand in large volume. Experimental program was carried out to study and comparison. The influence of utilization of waste foundry sand as a substitute material for fine aggregate in concrete manufacturing. In experimental program natural sand was partial replaced with waste foundry sand, with using M25 grades of concrete mixtures. Fine aggregate (river sand) was replaced with three different mixes with varying proportion of waste foundry sand as Mix{A of 20% (River Sand=80%, Molasses Sand=20%), Mix{B of 40% (RS=60%, MS=30%, GS=5%, CS=5%) and control concrete. Experimental investigation was performed in two parts one is plane cement concrete and another is reinforced cement concrete. In plane cement concrete, evaluate the mechanical properties such as compressive strength, flexure strength and modulus of elasticity. Same as durability properties like Acid attack, sulphate attack, acceleration carbonation, water permeability and rapid chloride penetration test (RCPT). In second part reinforced cement concrete RC beam element are tested. It is observed that workability of waste foundry sand concrete is tend to reduce. It may be due to high water absorption and finer particle size of the waste foundry sand. The results demonstrate that strength and durability properties of waste foundry sand concrete is marginal high then normal concrete, up to 40% of waste foundry sand replacement with natural river sand. Thus it is observed that more than 40% replacement is not suitable. It is evident that up to 20% replacement of river sand by the waste foundry sand possess the potential for offering better protection to concrete against various durability parameters. However, it is recommended to use some supplementary cementitious materials along with the waster foundry sand in concrete for ensuring its long term protection against various durability related regimes.

Experimental Investigation on Mechanical and Durability Properties of Recycled Aggregate Concrete Incorporating Flyash and Silicafume In the field of civil engineering, resources for making concrete are reduced day by day. So ingredients which are used for making concrete should be reused. Aggregate can be reused and can be produced recycled aggregate to replace natural aggregate in concrete. Recycled aggregate are comprised of crushed, graded inorganic particles processed from the materials that have been used in the constructions and demolition debris. The difficulty in using natural coarse aggregates for the production of concrete associate with the climate issues of natural aggregates makes the usage of recycled aggregate concrete (RAC) is the prime importance to protect the environment. Recycled aggregates are the aggregates produced from the processing of previously used construction materials such as concrete or masonry. Construction and demolished waste, tested specimens from laboratory, concrete from ready mix concrete plants and precasting units are some sources of recycled aggregate. In this work, recycled aggregate from laboratory waste used to make recycled aggregate concrete. Laboratory waste consists of concrete waste which includes only aggregates. Physical properties such as fineness modulus, density, specific gravity, water absorption of recycled aggregate are investigated. In experimental work recycled aggregate used as 0%, 50%, and 100%. Cement is replaced with flyyash and silicafume by 15% and 10% respectively in 50% and 100% recycled aggregate concrete. The results of mechanical properties and durability properties are compared. Results shows that as recycled aggregate content is increased in concrete, mechanical and durability properties are decreased. Cementitious material like silicafume and fly ash somewhat helps to improve the properties of recycled aggregate concrete. July 2017
Recycled Aggregate Pervious Concrete Pervious Concrete prepared with partially or fully replacing aggregates with recycled aggregates can be termed as Recycled Aggregate Pervious Concrete. It is a mixture of Cement, Coarse aggregate, Recycled Aggregate and water. In addition, investigation was carried out on the effects of incorporating recycled aggregate (25%,50%,75% and 100%) on the properties of pervious concretes. The pervious concrete properties were compared with normal pervious concrete without recycled aggregate. Permeability test of pervious Concrete at 28 days shows that with increase in Cement content permeability is decrease and with variation in sand content 0% to 20% permeability is decrease. Aggregate size of 20-10mm higher permeability than aggregate size of 10-06mm. July 2016
Durability Studies of Concrete Accelerated Carbonated Test and DIN Impermeability Test Concrete usage around the globe is second only to water. Concrete degrades over time; one process which is responsible for this is the absorption of carbon dioxide, known as carbonation of concrete. The alkaline conditions of hydrated cement paste are neutralized by carbonation. This neutralization, by dropping the pH of concrete, affects the protection of reinforcing steel from corrosion. Thus, if the entire concrete cover to steel were car- bonated, corrosion of steel would occur in the presence of moisture and oxygen. Impermeability of concrete is an ability of concrete to resist pressurized water penetration. Corrosion of the reinforcing steel is one of the most critical problem faced in RCC struc- tures. The more porous or permeable the concrete, the higher the rate at which contami- nants can penetrate and degrade concrete. Assessment of impermeability of concrete is necessary. Accelerated Carbonation Test includes evaluation of effects of environmental factors i.e. CO2 concentration, temperature and relative humidity. This investigation was carried out on five grades of concrete mixes i.e. M20, M25, M30, M35 & M40 at the age of 28 days and 180 days. DIN Impermeability Test includes evaluation of impermeability of M25 and M40 grade of concrete mixes by replacing cement with different mineral admixtures i.e. Fly ash, GGBFS, Rice husk ash, Silica fume and Metakaoline. During this investigation, effect of replacement of cement by mineral admixtures to impermeability of concrete is achived. July 2016
Parametric Study of Pervious Concrete Chaniging Void Content The main objective of this investigation is to achieve a range of compressive strength & permeability by changing the cement content. Generally in pervious concrete sand is not used but to increase the compressive strength of pervious concrete, coarse aggregates will be replaced by various percentage of sand. The main properties to be studied are void ratio, compressive strength & permeability. For the measurement of permeability, a setup is developed known as Falling Head permeability test which is readily used all over the world. Pervious concrete is produced using two size of aggregates. The first is 4.75-10 mm i.e. size A (passing from 10 mm and retaining on 4.75 mm IS sieve) and second is 10-20 mm i.e. size B (passing from 20 mm and retaining on 10 mm IS sieve). For this experimental investigation, cement content is varied from 250 kg/m3 to 450 kg/m3 at an interval of 50 kg/m3. The aggregate/cement ratio is kept constant as 4. Three w/c are used i.e. 0.3, 0.35 and 0.4. Also, sand is used as a partial replacement of aggregates ranging from 0%-40% at an interval of 10%. In pervious concrete as the density increases compressive strength increases but subsequently the Permeability decreases. Throughout the experimental investigation the density of pervious concrete ranged from 1860 kg/m3 to 2272 kg/m3. The 28 days compressive strength of pervious concrete ranges from 5.8 to 13.8 MPa for size A aggregates and 10.23 to 20.21 MPa for size B aggregates. The void content ranges from 11.78 to 25.72% for size A aggregates and 10.34 to 22.89% for size B aggregates. The permeability of pervious concrete ranges from 1.38 to 4.14 mm/s for size A aggregates and 1.03 to 2.07 mm/s for size B aggregates. The results shows the comparison between Compressive strength v/s Void ratio and Permeability v/s Void ratio. As the void ratio decreases the compressive strength increases and permeability decreases and vice versa. May 2015
Evaluation of strength and Permeability of Pervious Concrete Pervious concrete is a potential answer for taking out storm water runoff. The high level of porosity in pervious concrete adequately minimizes runoff from cleared territories. Pervious concrete can up root storm water more rapidly than conventional concrete which brings about enhanced skid resistance. The objective of this study is to investigate the effects of aggregate size and water cement ratio on strength and permeability of pervious concrete. The results of this study would lead to a better understanding of the manner in which aggregate size and water-cement ratio can be used to optimize a pervious concrete mixture depending on project or site-specification requirements. Three aggregate size 6-10mm, 10-20mm and mix of both in equal size are used. For each aggregate size three water-cement ratio 0.30, 0.35 and 0.40 are used. Cement content 375 kg/m3 are kept constant. Aggregate to cement ratio 1:4 also kept constant. In which mix aggregate gives better performance with maximum compressive strength 14.07 MPa with permeability 12.14 mm/sec. May 2014
