Unique Concrete Previous
Concrete previous – versions are unique and innovative tool for the management of rainwater. Former concrete used in the design of the building, and can help to qualify for the credit process LEED Green Building Rating System. Previous versions of concrete have been used successfully in various types of construction in applications such as parking lots, streets, squares, parks and natural, and sidewalks. While the former concrete can be used for a number of surprising applications, the main use of it is on the sidewalk.
The Concrete previous versions concrete performance made with the amount controlled by the total, water and cement. This for creating a block of the college particles cover with a thin layer of pasta design. Contains concrete former little or no sand mixture, and creates a void content widely. Using enough dough to coat and bind the total molecules together to create a system that is highly permeable, interconnected voids flowing quickly. Typically, between 15% and 25% of the cavity is achieved in the hardened concrete, and the rate of water flow through the former concrete is usually about 480 in. / H (0.34 cm / s), although it could be much higher. No mortar contents of the low and high porosity also reduces energy compared to conventional concrete mix, but enough power for many applications that are easily achieved.
Usually supported the former concrete pavement on the base of the stone formation hollow-uniform size where rainwater can be stored prior to seep into the ground below the layer. This system is basically a form of dry detention ponds that can reduce the need for expensive storm water detention pond systems and / kept wet, allowing more efficient use of land. As a result, the concrete pavement system transparent and two functions: 1) as a paved surface for driving, parking or walking, and 2), and the basin to store rainwater retention during storm events.
Leadership in Energy and Environmental Design LEED is a scoring system developed by the US Green Building Council (USGBC) to assess the environmental performance of buildings. LEED is, the consensus voluntary national standard for developing high-performance, sustainable buildings and grounds. Concrete previous versions can be lasting progress, but permeable, surface capable of supporting heavy traffic loads. Enjoy for applying the Concrete previous.
