High-performance low-shrinkage concrete containing lightweight aggregate and preparation method thereof
The invention discloses high-performance low-shrinkage concrete containing lightweight aggregate and a preparation method of the high-performance low-shrinkage concrete, and belongs to the technical field of concretes.According to the lightweight high-performance concrete, on one hand, through doping of lightweight components such as ceramsite and pottery sand, the apparent density of the concrete is greatly reduced, and the purpose of the lightweight high-performance concrete is achieved; meanwhile, by using a reasonable proportion, the lightweight aggregate is uniformly distributed in the concrete, so that the stress is uniformly distributed, the strength, bending resistance and impact resistance of the concrete are obviously improved, and the generation of concrete pores and macroscopic cracks can be effectively inhibited by adding the defoaming agent into the matrix concrete; the crack resistance, the tensile strength, the bending resistance and the impact resistance of the concrete can be improved; the method can be used for preparing series light concrete with the strength grade of LC60-LC80 and the density of 1700-2150kg/m degrees.
本发明公开了一种含轻质骨料的高性能低收缩混凝土及其制备方法，属于混凝土技术领域，该轻质高性能混凝土，一方面，通过陶粒和陶砂等轻质组分的掺加，大幅降低了混凝土的表观密度，达到了轻质高性能混凝土目的；同时使用合理配比，使得轻质骨料在混凝土中均匀分布，从而应力分布均匀，使混凝土强度、抗弯性能及抗冲击性能得到明显改善，在基体混凝土加入消泡剂，可以有效抑制混凝土气孔和宏观裂缝的产生，而且能够提高混凝土的抗裂、抗拉、抗弯、抗冲击性能；可制备强度等级LC60～LC80、密度1700～2150kg/m°的系列轻混凝土。
