本发明的主要目的是谋求用较贫配比的拌合料进行高强、均匀而稳定的施工;另外,还想提供操作性良好、在各种施工现场使用都很容易的拌合料制备方法。发明者采用了SEC混凝土的成壳技术。在混合搅拌时对表面水量调整后的砂子,先加入一部分必要的水,使其处于均匀的含水状态;再加水泥之类水硬性物质。使细骨料 The main purpose of the present invention is to seek a high-strength, uniform, and stable construction with a relatively poorly-mixed mix; in addition, it is desirable to provide a method of preparing a mix that is easy to handle and can be easily used on various construction sites. The inventors used SEC concrete shelling technology. In the mixing and stirring, the sand adjusted to the surface water quantity is firstly added with a part of necessary water to make it in a uniform moisture state, and then added with a hydraulic substance such as cement.
