METHOD OF PRODUCING ADMIXTURE

摘要

PROBLEM TO BE SOLVED: To efficiently produce the large quantity of an admixture capable of improving the tensile strength of concrete or mortar. SOLUTION: The method of producing the admixture for being mixed with the concrete, mortar or cement has a step (step 1) for preparing an aqueous solution by uniformly dissolving silicate in an acid, a step (step 2) for evaporating water from the aqueous solution by blowing a high temperature gas on the surface of the aqueous solution prepared in the step 1 while stirring the aqueous solution in a stirring vessel and a step (step 3) for solidifying the aqueous solution from which water is evaporated.
