Lightweight thermal-insulation prefabricated lightweight aggregate concrete and preparation method thereof
The invention discloses lightweight thermal-insulation prefabricated lightweight aggregate concrete and a preparation method thereof. The preparation method of the lightweight thermal insulation prefabricated lightweight aggregate concrete comprises the following steps: providing lightweight ultrahigh-performance slurry; uniformly mixing the light coarse aggregate and EPS particles, vibrating, compacting and stacking in a mold; pouring the lightweight ultrahigh-performance slurry into a mixture of light coarse aggregate and EPS particles which are closely stacked in advance, and then curing to obtain the lightweight heat-insulating prefabricated lightweight aggregate concrete. The light ultrahigh-performance slurry comprises the following raw materials: an ultrahigh-performance grouting material matrix and foam, and cement used by the ultrahigh-performance grouting material matrix is ordinary Portland cement and sulphoaluminate cement in a mass ratio of 1: (1.2-2.5). The lightweight thermal insulation prefabricated lightweight aggregate concrete provided by the invention has the advantages of good stability, difficult mold collapse, low density, high strength, small volume shrinkage and small heat conductivity coefficient.
本发明公开一种轻质保温预制轻骨料混凝土及其制备方法。轻质保温预制轻骨料混凝土的制备方法，包括如下步骤：提供轻质超高性能浆体；将轻粗骨料与EPS颗粒混合均匀后振动密实堆积于模具中；将轻质超高性能浆体浇筑于预先紧密堆积的轻粗骨料和EPS颗粒混合物中，随后经养护后制得轻质保温预制轻骨料混凝土；轻质超高性能浆体的原料包括：超高性能灌浆料基体和泡沫，且超高性能灌浆料基体所用的水泥为质量比为1：(1.2‑2.5)的普通硅酸盐水泥和硫铝酸盐水泥。本发明的轻质保温预制轻骨料混凝土具有稳定性好、不易塌模，密度低，强度高，体积收缩小，导热系数小的优点。
