| 摘 要： | 贵州是一个缺少天然砂的地区,其细集料基本采用母材为石灰岩人工机制而成,而石灰岩往往与泥夹石形式存在,在机制过程中会带入一定量的泥,主要研究砂中不同含泥量对混凝土工作性、强度、抗渗性及收缩性能的影响.

| Abstract: | Guizhou is an area where the natural sands are in shortage condition.The fine aggregate generally made from Limestone as base materials by manually or machine crushing.The Limestone always exists in the state of stone combined with soils so during the machine crushing process,the soil was brought into the sands.The Article mainly study the Influence of the different soil contents in sand on the concrete properties such as workability,strengths,permeability and shrinkage. |
