MANUFACTURING METHOD OF CONCRETE USING A SUPERPLASTICIZER COMBINED WITH CARBON AMINO SILICA BLACK, CAPABLE OF SUPPRESSING PENETRATION OF HARMFUL MATERIALS

摘要

PURPOSE: A manufacturing method of concrete using a superplasticizer combined with carbon amino silica black is provided to enhance compressive strength, tensile strength, and a coefficient of elasticity for concrete.;CONSTITUTION: A manufacturing method of concrete using a superplasticizer combine with carbon amino silica black uses 0.5-10 wt% of a polycarboxylic acid-based high functional water reducing agent based on binders of concrete. The polycarboxylic acid-based high functional water reducing agent includes 0.1-30 wt% of carbon amino silica black. The silica mole fraction of the carbon amino silica black is 0.1-20 wt%. The replacement rate (W/B) of the concrete is 15-50%. The concrete includes 25-100 wt% of cement, 0-40 wt% of blast furnace slag powder, 0-25 wt% of fly ash, and 0-10 wt% silica fume.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Compressive strength; (BB) 3 days; (CC) 7 days; (DD) 28 days; (EE) CASB mixing rate(%)
