How much does pervious concrete cost?
How much does pervious concrete cost?
Pervious concrete costs $8 to $16 per square foot installed, while plain concrete costs $4 to $8 per square foot….Pervious concrete cost vs. concrete.
| Factor | Pervious concrete | Regular concrete |
|---|---|---|
| Cost per square foot | $8 – $16 | $4 – $8 |
| 24’x24′ driveway cost | $4,600 – $9,200 | $2,300 – $4,600 |
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.
How long does permeable concrete last?
20-40 years
Pervious concrete is a strong and highly durable material. Parking areas properly designed and constructed will last 20-40 years with little or no maintenance.
How strong is pervious concrete?
In the laboratory, pervious concrete mixtures have been found to develop compressive strengths in the range of 500 to 4000 psi (3.5 MPa to 28 MPa), which is suitable for a wide range of applications. Typical values are about 2500 psi (17 MPa).
Is pervious concrete strong?
Strength and Durability Pervious concrete is a strong and highly durable material. Parking areas properly designed and constructed will last 20-40 years with little or no maintenance. Concrete strength can also be maximized by installing subgrade and subbase levels of course and/or fine aggregates beneath the pavement.
Does pervious concrete clog?
However, the pore structure of permeable concrete can become clogged by sediment particles and its ability to drain storm-water runoff gradually decreases (Deo et al. 2010. Permeability reduction in pervious concretes due to clogging: experiments and modeling.
Which material can be replaced in concrete for a strong pervious concrete pavement?
Which material can be replaced in concrete for a strong pervious concrete pavement? Explanation: Apart from replacement, there are many materials that can be used for substitution, for a strong pervious concrete pavement better option is to replace coarse aggregate.
Does pervious concrete crack?
A much smaller amount of drying shrinkage occurs in the placement of pervious concrete than dense, and it develops sooner, as well. This allows many pervious pavements to be constructed without crack-preventing control joints.
What are the benefits of pervious concrete?
Benefits of Pervious Concrete
- Eliminates untreated storm water and creates zero runoff!
- Directly recharges groundwater.
- Mitigates “first flush” pollution.
- Protects streams, watersheds, and ecosystems.
- Mimics the drainage and filtration of bioswales and natural soils.
- Reduces surface temperatures and heat island effects.
What is pervious concrete used for?
Pervious concrete has applications in sustainable construction, and is often used in sidewalks, parking areas, and greenhouses. Using pervious concrete is recognized as a Best Management Practice for Stormwater by the US Environmental Protection Agency (EPA), since it provides pollution control.
What is pervious concrete made of?
Pervious concrete is made with a narrow aggregate gradation, but different surface textures can be obtained through the use of different maximum sizes. The concrete in the box contained a 1/4-in. (6.5-mm) top size, while that below used a larger top size, 3/4 in. (20 mm).
How does pervious concrete lower project costs?
In doing so, pervious concrete has the ability to lower overall project costs on a first-cost basis. In pervious concrete, carefully controlled amounts of water and cementitious materials are used to create a paste that forms a thick coating around aggregate particles.
What is sustainablepervious concrete pavement?
Pervious concrete pavement is a unique and effective means to address important environmental issues and support green, sustainable growth.
Why are chemical admixtures used in pervious concrete?
Chemical admixtures are used in pervious concrete to obtain special properties, as in conventional concrete. Because of the rapid setting time associated with pervious concrete, retarders or hydration-stabilizing admixtures are commonly used.
