CEMENT COMPOSITION FOR HIGH FIRE RESISTANCE AND ULTRA HIGH STRENGTH ULTRA SELF-COMPACTING CONCRETE

摘要

PURPOSE: A cement binder composition for high fire-resistance and ultra high strength super fluidity concrete is provided to use a fiver for a spalling control, and a polysaccharide based thickening agent for securing the high fire-resistance. CONSTITUTION: A cement binder composition for high fire-resistance and ultra high strength super fluidity concrete contains 550~1,240 kg/cubic meter of binding material, 165~185 kg/cubic meter of combined water, 600~90 kg/cubic meter of fine aggregate, and 400~700 kg/cubic meter of coarse aggregate. The composition additionally contains 0.005~0.1wt% of thickening agent.
