随着建筑业的发展,以往现场配制砂浆根本无法满足现代砂浆施工的要求。由于现场配制的砂浆由现场操作人员控制,难免会产生配合比不准确、原料质量不符合要求、计量不准确等一系列问题。干粉砂浆是经烘干筛分处理的细集料与无机胶结料、保水增稠材料、砂浆掺合料和添加剂按一定比例混合而成的一种颗粒状或粉状混合物。它可以由专用罐车运输至工地加水拌和使用,也可以采用包装形式运到工地拆包后加水拌和使用。干粉砂浆早在加世纪50年代就在欧洲得到了普遍地应用。在欧洲,
With the development of the construction industry, past the preparation of mortar at the scene simply can not meet the requirements of the construction of modern mortar. Due to the site preparation of mortar control by the scene operator, will inevitably lead to inaccurate mix, raw material quality does not meet the requirements, measurement inaccurate and a series of issues. Dry mortar is a mixture of fine aggregate and inorganic binder, water-holding thickening material, mortar admixture and additives mixed in a certain proportion by drying and sieving, which is a granular or powder mixture. It can be transported to the site by a dedicated tanker to mix with water, can also be used to transport packaged form to the site after the demolition of water mixing. Dry mortar as early as the late 1950s in Europe has been widely used. in Europe,
