The pervious concrete was placed over the gravel layer and compacted using a manual compaction hammer due to space restriction. It is important to notice that compaction can alter pervious concrete characteristics [4]. 2.2. Pervious Concrete Characteristics The pervious concrete surface consists of a mix design containing a cement type CP V Ari .

and cylinders. The outcome of the experiment validated the fact that permeable concrete has lower compressive strength than conventional concrete (Chopra et al., 2007) MIX DESIGN: Pervious Concrete is a mixture of Cement, Coarse Aggregate / Gravel and Water. No Fine Aggregates are used for making pervious concrete.

Pervious concrete, sometimes referred to as “no-fi nes concrete,” is a mixture of hydraulic cement, coarse aggregate of smaller size, admixtures and water. Pervious concrete allows the water to percolate through the concrete into the sub-base and recharge the underground water level. Typically,

Pervious concrete, also known as porous concrete (enhanced porosity) or gap-graded concrete has little to no fine aggregates. Pervious concrete mixes consist of cement, single sized coarse aggregate and water (water/cement ratio ranging 0.3 to 0.4). It is reported that, the 28-day compressive strength of

ASTM C-1747 More important than compressive strength for pervious (my opinion ) Samples are molded per the standard and then tumbled (LA Abrasion) 500 cycles (no steel shot) Mass loss is measured – lower loss should mean tougher, more durable pervious. Results under 40% mass loss appear to represent good pervious mixes.

several types of permeable pavements: pervious concrete, porous asphalt, interlocking concrete pavingstones, grass grid pavers, among others. ***Note: "Pervious", "porous", and "permeable" are often used interchangeably by laypersons, although the terms are not technically the same. A pervious surface is "open to

2.2.3. Permeable concrete Description Permeable concrete, also known as pervious (or) porous concrete, gap-graded (or) enhanced porosity concrete, is concrete with reduced sand or fines and allows water to drain through it. . Pervious concrete pavement is a unique and effective means to address

content is more which introduces porosity, hence also called as permeable concrete and porous concrete. Due to the introduction of voids, the compressive strength of pervious concrete is less. A lot of research work is going on to increase the compressive strength of concrete. Hence due to having low strength as compared to conventional .

strength of pervious concrete. Very large size of aggregates can make concrete weaker in strength. On the other hand use of small aggregates can reduce its functional characteristic. Proper gradation is necessary for pervious concrete. Various studies (12), (22) and (23) used the gradations which were aimed at the porosity between 15 to 30%.

Most of the background reading and literature came from the American Concrete Institute's "Report on Pervious Concrete" ACI 522R-10 as it was felt it was the best place to start as this type of concrete has been used in America for more than 20 years. The initial mix design procedure was used from this document as a starting point.

concrete is light in weight (about to 2000 Kg/m3) pervious concrete. Void structure provides pollutant captures which also add significant structural strength as well. It also results in a very high permeable concrete that drains quickly. Pervious concrete can used in a wide range of applications, although its

Typically thirsty concrete has no fine aggregate or has little fine aggregate and has just appropriate cementious paste to overcoat the coarse aggregate particles while conserving the inter-relativity of the pores.

1.2 Constant head permeability test Permeability of the pervious concrete samples was measured using the constant head permeameter in accordance with Association of Japan Highway (1996) Guide. Fig.3 shows the actual setup of the constant head permeameter. The apparatus consists of a cylinder of diameter 150 mm with the constant upstream head during

This guide specification is not applicable to construction of pervious concrete pavement, two-lift concrete pavement, and roller compacted concrete. 1.2 End Product The end product for the work is the concrete pavement constructed using materials, equipment,

Permeable concrete is also known as "NO-FINES" or "PERVIOUS" or "Thirsty" concrete as it does not contain fine aggregates such as sand. Local rainfall information is important while installing permeable concrete. ( /-) 90 Litres water are used but not too much or you won't have permeable concrete.
