<p>PROBLEM TO BE SOLVED: To provide a curing method of waterproof sodium silicate curable substance which contributes to resource economization and environmental conservation because the sodium silicate curable substance does not redissolve into water. SOLUTION: When the sodium silicate is cured, calcium bisilicate or/and calcium oxide is used as curing agent and, thereby, the cured substance has water resistance. Further, this construction is constituted by an inorganic hollow body such as glass balloon and perlite balloon produced by using the curing method.</p> |
