中国硅酸盐学会水泥制品专业委员会在山东泰安市召开1983年年会。出席会议的有来自建材、水电、铁道、冶金、邮电、城建等系统的代表共74名。这次送交会议的论文,内容丰富,其中包括了混凝土与水泥制品的裂缝及其控制、减水剂的使用效果、水泥制品热养节能等七方面。与会代表提出了许多有益的建设,主要有: 1.对预应力混凝土电杆,应适当增配螺旋钢筋;对预应力混凝土轨枕,其端部可考虑配置箍筋,钉孔周围可考虑配置螺旋钢筋,同时适当提高混凝土的标号。 2.在水泥制品厂应大力推广有效的热养节能措施,如封闭热养、干式供热。 3.在水泥制品厂需进一步使用外加剂的
The China Cement Society’s Cement Products Professional Committee held its 1983 annual meeting in Tai’an City, Shandong Province. A total of 74 representatives from the building materials, hydropower, railways, metallurgy, post and telecommunications, and urban construction systems attended the meeting. The papers sent to the conference were rich in content, including cracks and control of concrete and cement products, the use of water reducing agents, and the thermal conservation and energy conservation of cement products. The delegates proposed a number of useful constructions, including the following: 1. Prestressed concrete poles should be appropriately equipped with spiral steel reinforcement; for prestressed concrete sleepers, stirrups can be considered at the ends, and spirals can be considered around the nail holes. Reinforcing steel, while properly raising the number of concrete. 2. The cement product factory should vigorously promote effective energy-saving measures for heat conservation, such as closed heat preservation and dry heat supply. 3. It is necessary to further use admixtures at the cement product factory
