筒装生料砂浆有关问题的研讨和建议

  一、提出筒装生料砂浆技术方案的原由
    近年来，在建设工程施工中，推广应用预拌砂浆、干粉砂浆，统称预拌（商品）砂浆，有了可喜的进展。但在日常工程质量监督检查中发现，当前的在建工程特别是市郊的中小型工程项目，应用预拌（商品）砂浆的覆盖面不广、使用率不高，有的区域尚处于空白状态。究其原因，经调查研究发现，目前有几种情况已不同程度地成为影响建筑砂浆商品化进展的难点。
    1、预拌（商品）砂浆成本问题。
    由于预拌（商品）砂浆成份配比中掺加料、外加剂较
Barreled raw mortar discuss relevant issues and recommendations

  A proposed barreled program of raw material Mortar Reasons
    In recent years, building construction, the popularization and application of ready-mixed mortar, dry mortar, collectively referred to as mixed (goods) mortar, with encouraging progress. But in everyday engineering quality supervision and inspection found that the current construction projects, especially in the outskirts of the small and medium projects, the application of ready-mixed (goods) mortar coverage not broad usage is not high, some areas still in the blank. The reason, after investigation found that there are several situations have varying degrees of progress in the commercialization of an impact on the difficulty of building mortar.
    1, mixed (goods) mortar cost.
    As the ready-mix (product) ratio of mortar mixed with feed ingredients, additives than
