全国混凝土构件生产节约水泥经验交流会于1987年11月16日至19日在洛阳召开。会议提供交流资料81份,有26位代表作了交流发言。这次会议的主要内容是交流节约水泥的经验。笔者从会议上了解到,近年来我国在节约水泥方面做了大量工作,取得了显著的技术经济效益和社会效益。目前我国混凝土预制构件的生产中可用于节约水泥的主要措施和途径有:1.在混凝土中掺用外加剂使用外加剂节约水泥不需要增加生产设备和改变生产工艺,因而是简单易行的方法。(1)使用减水剂掺于混凝土拌合物中对于水泥颗粒有强烈的分散作用,能改善混凝土
The National Experience on the Production of Concrete Components for Saving Cement was held in Luoyang from November 16 to 19, 1987. The conference provided 81 exchanges of information, and 26 delegates made exchanges. The main content of this meeting was the exchange of cement-saving experience. The author learned from the meeting that in recent years, China has done a lot of work in saving cement, and has achieved significant technical and economic benefits and social benefits. At present, the main measures and approaches that can be used to save cement in the production of concrete precast elements in China are as follows: 1. Adding admixtures to concrete The use of admixtures to save cement does not require additional production equipment and changes in the production process. It is a simple and easy method. . (1) The use of water-reducing agent mixed in concrete mixture has a strong dispersion effect on cement particles and can improve concrete
