Please Read: Standard industry practices recommend ordering 4% to 10% more concrete than is estimated from a volumetric calculation. Some of the situations this will account for are waste, spillage, over-excavation, spreading of forms, loss of entrained air during placement, settlement and a change in volume (hardened concrete volume is 1% to 2% less than that of plastic concrete). Anderson Concrete conducts yield tests to verify design weights and maintains certified scales, therefore is not responsible for shortages that arise from ordering issues.
Protection Measures Recommended When Either of These Two Conditions Exist:
Conditions not Favorable for Concrete Placement When Either of These Two Conditions Exist:
THIS WORKSHEET DOES NOT GUARANTEE SUCCESSFUL CONCRETE FINISHING AND SHOULD ONLY BE USED AS AN ADDITIONAL TOOL TO PREPARE FOR PLACEMENTS.
SURFACE EVAPORATION CAN BE SLOWED BY USING METHODS SUCH AS WIND BREAKS, FOGGING AND EARLY CURING, BUT DOES NOT GUARANTEE THAT PLASTIC SHRINKAGE WILL NOT OCCUR.
