摘要
通过分析我国工程造价信息管理所存在的问题,提出建立适合我国国情的工程造价管理信息系统,实现工程造价的动态管理。
Three or four compound proportions of cement, coal powder and crushed stones are arranged by a chosen stone material blend. This paper illustrates the effects on the compressive resistance of compound proportion by the differences of mixture＇s intensity in the early stage and the middle stage.
