<p><P>PROBLEM TO BE SOLVED: To provide a sulfuric acid-resistant mortar composition, a sulfuric acid-resistant concrete composition having high resistance to sulfuric acid, and a hardened matter thereof. <P>SOLUTION: The sulfuric acid-resistant mortar composition includes cement, fine aggregate and a naphthalene sulfonate condensate having a number average molecular weight of 2,000-6,000 and a weight average molecular weight of 3,000-30,000. The sulfuric acid-resistant concrete composition includes the sulfuric acid-resistant mortar composition, coarse aggregate and fine powder of limestone. The hardened matter of the sulfuric acid-resistant mortar and the hardened matter of the sulfuric acid-resistant concrete are obtained by hardening the sulfuric acid-resistant mortar composition and the sulfuric acid-resistant concrete composition respectively. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
