Concrete applications I CIMT 210 products Pervious Concrete(definition, application, history, application); stormwater management (benefits, Recommended Specifications); mix design (structural design). | Pervious Concrete: What is Pervious? Definition History Applications 2. Stormwater Management Benefits Recommended Specifications Hydrologic Analysis 3. Mix Design CONCRETE APPLICATIONS I CIMT 210 1. What is Pervious? DEFINITION (SEE VIDEO ON PERVIOUS CONCRETE) It allows rainfall to be captured and to percolate into the ground. It reduces stormwater runoff It recharges groundwater It supports sustainable construction 1. What is Pervious? B. HISTORY Its not a new technology (first used in 1852) 2. Federal Clean Water legislation (promotes it.) 1. What is Pervious? C. APPLICATION 1. Its high porosity provides is thermally insulating ( in walls of buildings) 2. It has good acoustical properties (for sound barrier walls). 1. What is Pervious? C. APPLICATION Table . Applications for Pervious Concrete Low-volume pavements Residential roads, alleys, and driveways Sidewalks and pathways Parking areas Low water crossings Tennis courts Subbase for conventional concrete pavements Patios Artificial reefs Slope stabilization Well linings Tree grates in sidewalks Foundations / floors for greenhouses, fish hatcheries, aquatic amusement centers, and zoos Hydraulic structures Swimming pool decks Pavement edge drains Groins and seawalls Noise barriers Walls (including load-bearing) 2. STORMWATER MANAGEMENT A. BENEFITS Its subbase may provide enough water storage capacity to eliminate the need for retention ponds, swales, and other precipitation runoff containment strategies. 2. Its drainage media for hydraulic structures, parking lots, tennis courts, and greenhouses. 3. It helps owners comply with EPA stormwater regulations 2. STORMWATER MANAGEMENT B.
