Grouting cement mortar composition and grout adopting same
The invention provides grouting cement mortar composition and grout adopting the same. The grouting cement mortar composition can keep good fluidity, avoid water bleeding or material separation, is high in strength and durability, has cracking preventing performance obtained through drying shrinkage reduction and is applied to machinery foundation and the like. The grouting cement mortar composition is characterized by containing a combination material, a coagulation retarding agent, a water reducing agent and fine aggregate, the combination material contains volcanic ash micropowder and a fast curing agent formed by cement, alumina silicate glass and gypsum, the water reducing agent at least contains a poly-carboxylate based water reducing agent, and the fine aggregate is heavy aggregate with the density larger than 3.0 g/ cm<3>. Further, the grout is formed by mixing the cement mortar composition and water.
