SULFURIC ACID-RESISTANT CEMENT, CEMENT PASTE, MORTAR, CONCRETE AND THEIR HARDENED BODY USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a sulfuric acid-resistant cement capable of obtaining high sulfuric acid-resistance and capable of improving spraying performance when the cement is used as a spraying material and to provide a cement paste, mortar, concrete and their hardened body using the cement. PSOLUTION: A water cement ratio is set to 56% and a fine aggregate cement ratio is set to 3.0 and an addition amount of the quick setting agent is set to 5-10 wt.% on the basis of a test determined in quality standard for a quick setting agent for shotcrete of JSCE-D102. The sulfuric acid-resistant cement having a mortar solidification starting time of 10-100 min is obtained and the spraying performance is improved when the cement is used as the spraying material.
