    摘要: PROBLEM TO BE SOLVED: To provide a high-strength cement-based hardened body with less self-shrinkability. SOLUTION: The high-strength cement-based hardened body with a compressive strength of 60 N/mm 2 or higher is the hardened body of a cement composition containing cement, a water reducing agent, an aggregate, water and a self-shrinkage reducing agent for cement comprising the oxyalkylene compounds represented by formula (1): RO-[(EO) m /(PO) n ]-H (wherein R is 8-14C alkyl; EO is oxyethylene; PO is oxypropylene; [(EO) m /(PO) n ] represents, as a whole, the single addition of ethylene oxide or propylene oxide, or block or random addition in combination use regardless of the order of the block addition; m is a number of ethylene oxide average addition moles of 0-10; n is a number of propylene oxide average addition moles of 0-5, provided that the total of m+n is 1-10).
