摘要
对各种普通预拌砂浆的配合比的设计、试配及应用机理的进行了研究。通过对掺入不同品种保水增稠材料和外加剂对预拌(湿拌)砂浆性能影响的试验,并根据各普通预拌砂浆的技术性能要求,研制出不同品种中各强度等级预拌(湿拌)砂浆的生产配合比。
The design,pre-mix and application mechanism of various normal premixing mortar mixture ratios.According to the normal premixing mortar technical characteristics requirement, production mixture ratios for different kinds of premixing mortar with various grades are developed by the effects of adding different retention thickeness and additives to the premixing mortar characteristics.
