摘　　要：采用标准养护、蒸汽养护和匹配养护的3种不同的养护方式,研究了白色高强混凝土在不同养护方式下强度的发展规律,结果表明:蒸汽养护和温度匹配养护可以显著提高白色混凝土早期强度,白水泥复合胶凝材料体系配制的混凝土在蒸汽养护和温度匹配养护条件下后期强度超过纯白水泥混凝土,蒸汽养护和温度匹配养护条件对纯白水泥混凝土后期强度发展不利,但是可以促进白水泥复合胶凝材料体系混凝土后期强度发展。白水泥-磨细矿渣粉复合胶凝材料体系配制的混凝土在蒸汽养护和温度匹配养护条件下抗压强度高,后期增长明显,其在大体积混凝土中和预制构件中应用效果较好。Three different curing methods,standard curing,steam curing and matching curing,were used to study the development law of strength of white high strength concrete under different curing methods.The results show that steam curing and temperature matching curing can significantly improve the early strength of white concrete.The concrete prepared by white cement composite cementitious material system can be cured under steam curing and temperature matching curing conditions.The later strength of white cement concrete is higher than that of pure white cement concrete.Steam curing and temperature matching curing conditions are unfavorable to the later strength development of pure white cement concrete,but they can promote the later strength development of white cement composite cementitious material system concrete.Under the condition of steam curing and temperature matching curing,the compressive strength of the concrete prepared by the white cement ground slag composite cementitious material system is high,and the growth is obvious in the later stage,which has a good effect in the application of mass concrete and prefabricated components.
