PURPOSE:To make it possible to remarkably promote strength over a long period of time by including cement, water, aggregate, a water-reducing admixture and a specific alcohol-based compound. CONSTITUTION:The concrete composition is obtained by adding water, an aggregate, 0.05-5wt.% water-reducing admixture and 0.5-10wt.% alcohol-based compound of the formula RO(AO)nH [R is 4-6C alkylene; A is 2-3C one or two or more alkylene; n is 0-10] to cement and kneading the mixture. |
