摘要
讨论了干粉砂浆研究和开发应用的重大意义。对掺加石粉、纤维素和引气剂后砂浆的性能进行了对比 ,并通过试验研制出各项性能均符合标准要求的不同强度等级的干粉砌筑砂浆和干粉抹灰砂浆。还对所选用的外加剂和填充料的作用机理进行了解释。
The Significance in development and application of dry-mixed mortars is described. Based on the effects of limestone powder, cellulose and air-entraining agent on properties of mortar, the dry-mixed mortars (for masonry or plaster) with different strength grade, which properties are completely to meet the requirments in relative standards, are prepared. The mechanisms of the selected admixtures and limestone powder are discussed as well.
