CEMENT MORTAR AND SHOOTING MATERIAL

摘要

A dry cement mortar comprising a cement and an aggregate having a ratio of the maximum particle diameter thereof to the inner diameter of a pipe to be used for transferring the resultant cement mortar of 0.1 or less. The dry cement mortar may further comprise calcium aluminates, a gypsum, a slaked lime containing material, organic acids, fibers, a thickener, a water reducing agent, a water-absorbing agent, an alkali metal sulfate and/or an alkali metal carbonate. An accelerator may be incorporated in a wet cement mortar which has been prepared by mixing the dry cement mortar with water. The dry cement mortar can be used for providing a shooting material which allows the decrease of troubles due to a long run working with the material and the maintenance of a homogeneously mixed state of the material.
