| 摘 要： | 通过掺入外加剂,改变胶结材料和粗细骨料的含量及种类,改善混凝土的配合比,使混凝土的自重力大于混凝土的屈服应力,混凝土的流动性增大,又具有足够的黏度和塑性.能自由流淌并充填模板内的空间,它不需要外加振动力,而依靠自重力作用即可获得密实且均匀的胶凝结构.

| Abstract: | By means of incorporation admixtures to alter cement materials and the contents and the types of coarse-fine aggregate in the concrete.Through improving the concrete mix proportion,concrete gravity is more than the concrete yield stress,and the mobility of concrete is augmented,enough sufficient viscosity and plasticity are reached.It does not need additional vibrating force to flow freely and fill the inner space,and it can obtain density and uniform cementitious structure by relying on the self-gravity. |
