摘要：
A pressure water absorption inhibitor for lightweight aggregates which comprises an aqueous dispersion of a polymeric substance having a viscosity which permits the aqueous dispersion to enter the fine pores in the surface layer of a lightweight aggregate and which dispersion is capable of being thickened to a viscosity of not less than 50 times the viscosity before thickening by elevation of the pH.
