LOW SELF-SHRINKABLE CEMENT COMPOSITION OF HIGH PORE PHASE TYPE

摘要

PPROBLEM TO BE SOLVED: To provide a low self-shrinkable cement composition of a high pore phase type in which the self-shrinkage is low even when used in a low water cement ratio conventionally causing the self-shrinkage regardless of a high amount of the pore phase, and a large quantity of industrial by-product/industrial waste rich in an AlSB2/SBOSB3/SBcomponent can be used as a cement raw material. PSOLUTION: The cement composition containing cement clinker and gypsum is prepared so that the total quantity of CSB3/SBA and CSB4/SBAF is 20-30 mass% and the quantity of f.CaO is 0.28-1 mass%.
