What is thirsty concrete?
The thirsty concrete doesn’t actually “absorb” water, but rather drains it into the ground. The material is made up of tiny pieces of granite that are packed together. Traditional concrete, on the other hand, is sand based. The new concrete can be used in three different designs, each made up of two layers.

What happens if you put thirsty concrete in freezing weather?
If thirsty concrete was used in freezing climates, the water trapped inside would solidify and expand. The expansion would cause the permeable layer to bend or crack. The idea of “thirsty” concrete has made its way to the United States, too.
How does high-tech concrete work?
In a statement , Tarmac said: “The high-tech concrete works by having a permeable layer on top, which allows water to drain through a matrix of large pebbles and then down into a loose base of rubble beneath.” The water is then fed into a drainage system that’s connected to groundwater reservoirs.

And just enough water to hydrate the cement. Almost any rock will do round.
How is pervious concrete made?
Pervious concrete is made from carefully controlled amounts of water and cementitious materials used to create a paste that forms a thick coating around aggregate particles. Unlike conventional concrete, the mixture contains little or no sand, creating a substantial void content – between 15 to 25 percent.
What is absorbent concrete?
Enter absorbent concrete. Where conventional concrete lets relatively little water through, absorbent concrete appears to drink it down. Its secret: a network of gaps that allow water to slip through to the ground below or to pipes which whisk it away.
Is there concrete that absorbs water?
Topmix Permeable, a fast-draining concrete, can absorb up to 1,000 liters of water per minute per square meter.
What are the materials used in pervious concrete?
Pervious concrete consists of cement, coarse aggregate (size should be 9.5 mm to 12.5 mm) and water with little to no fine aggregates. The addition of a small amount of sand will increase the strength. The mixture has a water-to-cement ratio of 0.28 to 0.40 with a void content of 15 to 25 percent.
Where does water go in permeable concrete?
Pervious concrete pavement is a pavement type that allows rainwater and other sources of water to percolate into the base layer below the concrete. Thus allowing the base material to absorb and control the flow rate of the water as it moves off site.
What is thirsty concrete?
The thirsty concrete is also called as pervious concrete, Permeable concrete, No fines concrete and Porous pavement. This concrete is mainly used in the places where the water is stagnant. The Main use of the thirsty concrete is to transfer the stagnant water from the top surface to the ground surface (Soil).
What is the best water absorbing material?
Moisture Absorbing Fabrics The most common absorbent fibre used is cotton, but other fabrics have recently been designed that are more absorbent, such as modal, micro-modal, Tencel®, and other viscose-based fibres. All of these are made from the same base material – plant cellulose – which loves water.
How much water can pervious concrete absorb?
Topmix Permeable Concrete Can Absorb an Impressive 4 Liters of Water per Minute.
Does Portland cement absorb water?
During the curing process, water that was used to create the concrete evaporates from the mixture. The bubbles leave behind a system of small tunnels and air pockets within the concrete. Because of all these voids, concrete has a porous structure that absorbs water.
Does hardened concrete absorb water?
Yes, concrete can absorb water because it's porous like a sponge.
How does permeable concrete work?
Pervious concrete is a special type of concrete with a high porosity, made from a mixture of cement, water, coarse aggregate and a minimal amount of fine aggregate (sand). Pervious concrete creates a porous medium, which allows water from precipitation and other sources to pass through and reach the underlying soil.

What is water permeable concrete?
Water permeable concrete refers to the water permeable pavement made by cement concrete or bituminous concrete while a lot of people may be confused with them. Actually, they are all mixed by coarse aggregates (or stones) and binding materials (cement or asphalt) and after they mixed together, porosity will be increased among aggregates, which explains the reason why their permeability is so good.
What is the difference between normal concrete and previous concrete?
The biggest difference between normal concrete and previous concrete is structure density and porosity, which affect concrete strength to a certain extent. Therefore, water permeable pavement is normally used in those with lower loading capacity, such as sidewalk, square and so on. Besides, in dusty conditions, pores will be jammed by dusts gradually then lose the permeability effect. Consequently, to strengthen the bearing capacity of pavement and keep the permeability effect are of great importance.
Is pavement a thin layer?
Additionally, the structure of pavement is not just a thin layer but with several layers, such as roadbed, bedding cushion, sub-base course, base course and more. Therefore, all the above layers should be permeable in order to achieve excellent permeability of the whole pavement.
What is thirsty concrete?
Worldwide a great research is currently being conducted on the storm water management in concrete. Concrete is an artificial stone-like material used for various structural purposes. The binding material cement and various aggregates are made by through mixing of stone chips, recycled aggregate, etc… with water and allowing the mixture to harden by hydration. Number of research has been done to find an alternate material in concrete. The thirsty concrete is also called as pervious concrete, Permeable concrete, No fines concrete and Porous pavement. This concrete is mainly used in the places where the water is stagnant. The Main use of the thirsty concrete is to transfer the stagnant water from the top surface to the ground surface (Soil). During rainy seasons the water is stagnant at one place. Sometimes, there is no proper management practice available. To overcome these defects the thirsty concrete is used. This concrete is used as a paving material due to its efficient to the water is allowed to pass through itself to maintain groundwater level and storm water runoff is minimized. It will help to increase the low ground water level and agricultural problems. In this thirsty concrete we are planned to use the recycled aggregates instead of the normal aggregates and we are going to do the probe on the thirsty concrete with normal aggregate and the thirsty concrete with recycled aggregates. A concrete mix ratio of 1:3 was obtained as per BIS method for our experimental work. Water cement ratio 0.35 has been adopted and performance of concrete with treated normal and recycled aggregate is investigated.
What is pervious concrete pavement?
Pervious concrete is a relatively new concept for rural road pavement, with increase into the problems in rural areas related to the low ground water level, agricultural problem. Pervious concrete has introduced in rural road as a road pavement material. Pervious concrete as a paving material has seen renewed interest due to its ability to allow waterto flow through itself to recharge groundwater level and minimize storm water runoff. This introduction topervious concrete pavements reviews its applications and engineering properties, including environmentalbenefits, structural properties, and durability.In rural area cost consideration is the primary factor which must be kept in mind. So that in rural areas costly storm water management practices is not applicable. Pervious concrete pavement is unique and effective means to meet growing environmental demands. By capturing rainwater and allowing it to seep into the ground. This pavement technology createsmore efficient land use by eliminating the need for retention ponds, swell, and other costly stormwater management devices.
