摘要
冬季混凝土掺防冻剂是保证强度不受损失的有效方法 ,实际掺量存在不合理性。从现行规范及理论上对混凝土早期受冻临界强度进行探讨 ,提出其掺量应以水灰比 ,水泥品种和施工时温度为参数控制 ,减化计算公式并在实践中完善。
Addition of an anti\|freezing agent to concrete is an effective way to assure the requiring strength. But the actual adding quantity is unreasonable. The paper discusses the early frozen critical strength of the concrete based on standards and the theory. To control the adding quantity accrding to water\|cement ratio, the variety of concrete and its construction temperature is proposed. And simplify the calculating formula should be simplified and perfected in practice.
