Abstract

Ultra-high strength concrete has the characteristics of high strength, good durability and more economical, and gradually meets the requirements of the new era, so it is of great significance to study ultra-high strength concrete. In this paper, ultra-high strength concrete is prepared by removing coarse aggregate from ordinary Portland cement superfine and highly active mineral admixture polycarboxylic acid high performance water reducer. The compressive, flexural strength and flexural ratio of ultra-high strength concrete with different mix ratios and the optimum ratio of ultra-high strength concrete of sea sand basalt fiber are obtained based on orthogonal test, so as to realize the safe use of undisturbed sea sand.
