1、压浆料的拌合比例为：水:压浆料=27(±1):100。2、搅拌：应采用转速不低于1000rpm/min高速制浆机搅拌，通常适合的搅拌次序是：先将水加到相应刻度，开启制浆机，均匀加入压浆料粉料，加入完毕后再搅拌3～5分钟即可压浆。3、压浆：在搅拌后尽快压浆，应采取通常的压浆方法。4、养护：浇筑过的区域如果是曝露的，应适当采取养护措施。5、清洁：用水清洁所有施工工具和设备。6、保护措施：施工过程中要戴保护手套和护目镜。<img

                                                                      压浆料采用复合牛皮纸袋包装，40kg/袋。贮存期：自生产之日起有效贮存期为6个月。应贮存在阴凉、干燥、通风的库房中，不可曝晒，不可雨淋，冬季应注意防冻。<img alt=""
