PROBLEM TO BE SOLVED: To provide a plastic grout in which any hardening of a liquid material used or any reduction in flowability of the liquid material with the lapse of time, is prevented from being caused even when the liquid material contains no retarding agent. SOLUTION: The production process of this plastic grout comprises: preparing an alkaline liquid material (liquid stimulant referred to as liquid A) that contains a hardening assistant such as stimulant containing calcium hydroxide or the like, (more specifically, e.g. lime, gypsum, hydrated cement, or the like); preparing another liquid (hardening liquid referred to as liquid B) containing a latent hydraulic material (such as blast-furnace slag or pozzolan) and a plasticizing material (such as bentonite); and agitating and mixing the liquid A and liquid B together. |
