摘要
近年来,随着水利水电事业发展,混凝土研究也步入高科技领域发展的关键时期。施工中科学控制其温度、裂缝等相关技术指标,最大效益地发挥混凝土的工作性能,以满足工程要求,节约水泥、降低成本、加快工程进度。通过多年的水利工程施工现场试验,本人查阅有关混凝土内部应力方面的专著,对混凝土温度裂缝产生的原因、现场混凝土温度的控制和预防裂缝的措施进行论述。
In recent years, with the development of water conservancy and hydropower, concrete high-tech field research into the critical period of development. Construction of science to control its temperature, cracks and other related technical indicators, the most effective performance concrete play to meet the engineering requirements, saving cement, reduce costs and speed up the progress of the project. Construction of water projects through multi-year field test, I have access to the concrete internal stress field, and temperature cracks of concrete causes the concrete temperature at the scene of the control and orevention measures on the cracks.
