COAGULATING AND HARDENING ACCELERATOR STABILIZED AT LOW VISCOSITY

摘要

PROBLEM TO BE SOLVED: To provide an accelerator for coagulating and hardening the water- hardening type binder, especially those not showing alkaline characteristic being free of alkaline metals and chlorides. ;SOLUTION: This coagulating and hardening accelerator comprises an aluminum salt, a complexing agent, a corrosion inhibitor and, as the case maybe, an inorganic and/or organic thixotropic agent. By using this accelerator, coagulation time can be shortened and high compression strength can be rapidly revealed as well as plugging of the spray nozzle and corrosion of spraying tool can be prevented.;COPYRIGHT: (C)2001,JPO
