Abstract
PURPOSE:To obtain the titled composition providing a cement cured material developing required strength at initial age and having extremely high strength, having a sufficient pot time, enabling rapid and efficient operation, by blending a cement substance with fine powder, a high-performance water reducing agent, a setting adjuster and a specific amount of an Al-containing hardening accelerating substance. CONSTITUTION:100pts.wt. powder consisting of (A) 60-95pts.wt. cement substance having 10-20mu average particle diameter and (B) 40-5pts.wt. ultrafine powder (e.g. silica dust) having an average particle diameter smaller than that of the component A by one or more figures is blended with (C) <=10pts.wt. high-performance water reducing agent such as naphthalenesulfonate, (C) <10pts. wt. Al-containing hardening accelerating substance such as calcium aluminate (solid solution), (E) <=10wt.% based on 100pts.wt. sum of the components A+B+C of a setting adjuster such as boric acid (salt) and optionally (F) an aggregate having >=6 Mohs hardness or >=700kgf/mm<2> Knoop indenter hardness and the blend is kneaded with 13-35pts.wt. water.
