ACID RAIN-RESISTANT LIGHTWEIGHT CELLULAR CONCRETE AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain lightweight cellular concrete without rusting internal steel bars for reinforcing by acid rain when waterproof treatment is not applied. SOLUTION: This lightweight cellular concrete comprises an organopolysiloxane therein or has coated layer of the organopolysiloxane on the surface thereof. The lightweight cellular concrete can be produced by adding and mixing the organopolysiloxane in mixing with raw materials or applying the organopolysiloxane to the surface of the resultant lightweight cellular concrete.
