SULFURIC ACID RESISTANT CEMENT COMPOSITION, SULFURIC ACID RESISTANT MORTAR COMPOSITION, AND SULFURIC ACID RESISTANT CONCRETE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a sulfuric acid resistant cement composition having excellent applicability and giving a hardened body having improved sulfuric acid resistance, and a sulfuric acid resistant mortar composition and a sulfuric acid resistant concrete composition using the same.SOLUTION: The sulfuric acid resistant cement composition contains 0.3-5 pts.mass formalin condensate of naphthalene sulfonic acid and/or salt thereof and 0.05-20 pts.mass organic compound being a polymer and/or its salt of a compound which has unsaturated rings, and in which each ring of the unsaturated rings has one or more sulfo groups, to 100 pts.mass cement. The sulfuric acid resistant mortar composition contains fine aggregate in the sulfuric acid resistant cement composition and the sulfuric acid resistant concrete composition contains coarse aggregate in the sulfuric acid resistant mortar composition.
