为使混凝土免遭冻害的各种措施,诸如掺用复合防冻剂,选用早强水泥、蓄热保温和加热设施等,已被广泛应用并受到重视。而应用“混凝土成熟度”这一指标来控制冬期施工的混凝土质量,欧、美、日等一些国家已较普遍采用。 Various measures to protect concrete from freezing damage, such as the use of composite antifreeze agents, the use of early-strength cement, heat storage, heat preservation, and heating facilities, have been widely applied and valued. The use of the “maturity of concrete” indicator to control the quality of concrete in winter construction has been widely adopted in some countries such as Europe, the United States, and Japan.
