description PROBLEM TO BE SOLVED: To obtain a modifier of cement grout capable of preventing bleeding and also generating of hardened contraction crack by adding a small amount thereof to usual grout material. SOLUTION: This cement grout modifier contains SiO2 , Al2 O3 and a minute amount of Fe2 O3 , and is composed of an inert fine hollow spherical light weight aggregate having a dry true specific gravity within a range of 0.7-0.9 and 0.05-5 pts.wt. of a powder wet dispersant based on 100 pts.wt. of the fine hollow spherical light weight aggregate, 0.5-10 pts.wt. of a powder viscosity conditioner, as necessary, and further 10-250 pts.wt. of emulsion-formable resin powder, as necessary. A grout hardened material formed from a grout solution mixed with the modifier does not generate bleeding nor crack and further has an excellent compression strength.
