在传统上,混凝土是按强度进行设计的,对混凝土的质量的最终标准主要是强度.因此混凝土生产者对水泥品质的要求也是强调强度;强度越高的水泥被认为质量也越高.如此的发展,造成近年来混凝土结构出现裂缝尤其是早期开裂的现象日益普遍.其原因很复杂.单从水泥来说,比表面积、矿物组成中C3A、C3S、碱含量的增加,热水泥的出厂,都增加了开裂的敏感性,降低了流变性能,是原材料中影响混凝土质量主要原因.应当把抗裂性作为水泥品质的重要要求,并限制出厂水泥的温度.（接上期）4水泥细度对混凝土工作性的影响目前我国混凝土尤其是中等以上强度等级的混凝土普遍使用高效减水剂和其他外加剂.当高效减水剂产品一定时,水泥的成分（主要是含碱量、C3A及其相应的SO3含量）和细度是影响水泥和高效减水剂相容性的主要因素.水泥细度的变化加剧了水泥与高效减水剂相容性问题.近两年时有发生高效减水剂的用户和厂家的纠纷.为此,天津雍阳外加剂厂丘汉用不同细度的天津P．O525水泥和拉法基P．O525水泥分别掺入不同量的UNF－5AS,进行相容性实验.采用水灰比为0．29的净浆,分别在搅拌后5分钟和60分钟后量测...
Traditionally,concrete design is based on the strength and quality of concrete is the ultimate strength of the standard.So producers of cement concrete quality is the emphasis on strength; intensity the higher the quality of the cement is considered higher.The development of the case,resulting in cracks in concrete structures in recent years,especially the phenomenon of early cracking is increasingly common.The reasons are complex.From the cement,the specific surface area,mineral composition of C3A,C3S,the increase in alkali content,heat cement factory,are to increase the sensitivity of the crack and reduce the rheological properties,is the quality of raw materials,mainly concrete.Should be the crack of cement quality as an important requirement,and limit the temperature of the cement factory.(Connected to a view) 4 fineness of cement concrete work on the impact of China's more than concrete,especially middle-strength grade of concrete commonly used superplasticizer and other admixtures.When the product must superplasticizer,the cement composition (mainly the amount of alkali,C3A and SO3 contents of the corresponding) and the fineness of cement affect superplasticizer compatibility and a major factor.Changes in cement increased fineness of cement and superplasticizer compatibility.Occur from time to time over the past two years Superplasticizer users and manufacturers of the dispute.To this end,Yong Yang admixture plant in Tianjin in different fineness丘汉Tianjin P.P.Lafarge Cement and O525 O525 cement mixing different amounts of,respectively,UNF-5AS,compatibility to experiment.0.29 water-cement ratio for the use of the paste,stirring,respectively,after 5 minutes and 60 minutes after the measurement ...
