Strength Characteristics of Blast-Furnace Cement Mortar with Silicate-Type Surface Penetrants
Concrete-using blast-furnace cement is more effective in increasing long-term strength, suppressing chloride-ion permeation, and alkali-silica reaction than ordinary cement. However, its strength development takes time, and it requires proper curing. In Japan, surface penetrants are used to maintain existing structures. In addition, the latent hydraulic property is promoted because the silicate-type surface penetrants are alkaline. The cover concrete becomes dense by reacting with the unreacted slag in the blast-furnace cement. The curing period can be shortened, and the quality of the cover concrete can be improved using this mechanism, leading to a new curing method. Therefore, in this study, we prepared a specimen in which 28 days old blast-furnace mortar was supplied with the amount of silicate-type surface penetrants used and an aqueous solution of calcium hydroxide as a reaction aid. We investigated its effect on strength characteristics.
