Ultra-high-performance self-compacting concrete contains silica fume at a rate of up to 15 parts to 100 parts of cement

摘要

Concrete is the bauxite sheet sand ground of calcining and from 1 to 10 millimeter of change of size by cement admixture, silicon ash percentage and 90 particle less than 1 milli circular mil and average-size 0.5 milli circular mil, defoaming agent, super plasticized water-reducing agent, water and optional fiber. Silicon ash indicates to be up to 15 component for every part of cement. Concrete also contains ultra micron calcium carbonate, in this way, providing partial size is more than 4: 57 classification with cement, sand and silicon ash.
