WHAT TEST DO YOU PERFORM ON CONCRETE TO EXAMINE STRENGTH?
CYLINDER TEST
WHAT TEST DO YOU PERFORM ON CONCRETE TO EXAMINE WORKABILITY?
SLUMP TEST
WHAT ARE THE ENVIRONMENTAL IMPACTS OF CONCRETE? (4)
ENERGY: 2% OF TOTAL ENERGY CONSUMPTION BY U.S. MANUFACTURING
EMISSIONS: CEMENT SECTOR 5% OF ALL MAN-MADE CO2
EXTRACTION: ECOSYSTEM DEGRADATION FROM MINING OR DREDGING
WATER: CONSUMPTION (1 BILLION GALLONS PER YEAR) AND POLLUTION (INCREASES pH)
HOW DOES ONE DECREASE THE ENVIRONMENTAL IMPACTS OF CONCRETE?
DECREASE EMISSIONS
UTILIZE RECYCLED AGGREGATES
INCREASE CURING PERIOD
REDUCE PORTLAND CEMENT
WHAT IS FLY ASH?
WASTE PRODUCT, DECREASES CEMENT USE, DECREASE PERMEABILITY
OTHER CONCRETE PRODUCTS
