Green technologies like pervious concrete and porous asphalt are being increasingly used in road construction in India. Pervious concrete allows water to pass through, reducing runoff. It consists of cement, coarse aggregates, and admixtures with high porosity (16% void space). Porous asphalt also has high porosity and consists of layers of asphalt, crushed aggregates, and geotextile. Both technologies reduce stormwater runoff and promote groundwater recharge compared to conventional pavements. They also provide environmental, economic, and safety benefits.Permeable concrete pavement

This document summarizes a study on the characteristics of pervious concrete. The study tested 7 different mixes of pervious concrete that varied the type and size of coarse aggregate and use of fine aggregate. 42 concrete specimens were cast and tested for compressive strength, flexural strength, and void ratio. The mix with river sand fine aggregate and 12mm coarse aggregate (M4) performed best with 83% higher compressive strength, 72% higher flexural strength, and 51% lower void ratio than the control mix without fine aggregate (M1). In general, the addition of fine aggregate improved the strength of pervious concrete while reducing the void ratio.Pervious Concrete: Getting Down to the Details

This document discusses pervious concrete, including its history, composition, applications, advantages, and disadvantages. Pervious concrete is a type of concrete with high porosity that allows water to pass through, helping reduce runoff. It was first used in Europe in the 1800s and came to the US after WWII. It allows stormwater to soak into the ground rather than running off surfaces, reducing flooding and pollution. Pervious concrete is composed of cement, coarse aggregates with little fine aggregates, and water. It has a variety of applications like driveways, sidewalks, and parking areas. Advantages include reducing runoff and flooding, while disadvantages include needing maintenance to avoid clogging.An Experimental Paper on Compressive Strength of Pervious Concrete

Pervious concrete has been in use in many countries over more than a century. Its higher porosity helps in percolating rain water directly to ground and thereby helps in recharging groundwater aquifer. In this study, pervious concrete of sizes of 6.3mm size aggregate were prepared with different water cement ratios to find the compressive strength. The purpose of this project is to analyze the feasibility of producing highly sustainable no fine concrete mixtures and evaluating the effect of W c ratio on the properties of pervious concrete. Porous concrete is produced by using ordinary Portland cement, coarse aggregates, and water. This concrete is tested for its property compressive strength. The results showed that the water cement ratio showed significant effect on compressive strength of Pervious concrete. S. Suryasri | Mr. K. S. B.

This project evaluated alternative low-cost waterproofing materials for small construction sites in Northern Province, Sri Lanka. Three cement-fevicol mix tanks and three lime-fevicol mix tanks were constructed and subjected to ponding, durability and bonding tests. Results found the lime-fevicol mix tanks performed better with minimal leakage observed and a protective lime layer forming on the water surface over three days, indicating potential as an effective and affordable waterproofing solution. Cost analysis found the lime-fevicol mix cost Rs. 690 per square meter compared to over Rs. 1,000 for standard materials, suggesting it can help encourage waterproofing in small northern constructions.Statement of Qualification

This document presents an experimental investigation on the use of artificial sand to replace natural sand in self-compacting concrete. Self-compacting concrete is able to flow and fill formwork without vibration. Due to increasing demand and decreasing availability of natural sand, artificial sand produced from crushing rocks is a potential substitute. The study examines the effects of replacing natural sand with 0%, 25%, 50%, 75%, and 100% artificial sand on the compressive strength and workability of self-compacting concrete over curing periods of 7, 14, and 28 days. Tests are conducted on fresh and hardened concrete to evaluate properties like slump flow, passing ability, and compressive strength. The results are analyzed to understand how artificial sand substitution impactsUse of Pervious Concrete in Pavements
