Title:
CEMENT ACCELERATOR
Document Type and Number:
Japanese Patent JPH09165246
Kind Code:
A
Abstract:

To obtain a sprayable cemental composition capable of improving the working environment by using a specific compound prepared from sodium aluminate and an acid as a cement setting and hardening accelerator.

This cement setting and hardening accelerator is represented by the formula, Al(OH)x(R)y {R is a basic anion other than sulfate radical; [(x)+(y)] is 3}. The basic anion R is preferably derived from an acid, RHn [(n) is a number capable of completely satisfying all the valences of R] (except sulfuric acid). The cement setting and hardening accelerator is added to a cemental composition at the place of a nozzle is method for preparing the sprayable cemental composition and spraying the resultant cemental composition from the nozzle on a substrate.
