Expanded perlite 3D printing light high-strength concrete and preparation method thereof
The invention relates to the technical field of building materials, in particular to expanded perlite 3D printing lightweight high-strength concrete and a preparation method thereof. Raw materials of the thermal insulation mortar comprise the following components in parts by weight: 500-700 parts of cement, 100-150 parts of fly ash, 100-150 parts of silica fume, 180-220 parts of water, 600-800 parts of sand, 12-18 parts of pre-wetted expanded perlite, 10-15 parts of a water reducing agent, 0.7-1 part of a thickening agent, 20-25 parts of an accelerator, 2-3 parts of rubber powder and 30-50 parts of fibers. According to the preparation method of the 3D printing light-weight high-strength concrete provided by the invention, the expanded perlite is subjected to surface modification treatment by adopting the surface modifier, and then the surface-modified expanded perlite is subjected to pre-wetting treatment; the expanded perlite 3D printing light-weight high-strength concrete with excellent construction performance and mechanical performance is prepared through a secondary stirring process.
本发明涉及建筑材料技术领域,特别涉及一种膨胀珍珠岩3D打印轻质高强混凝土及其制备方法。按重量份计,原料包括以下组分:水泥500~700份、粉煤灰100~150份、硅灰100~150份、水180~220份、砂600~800份、预湿膨胀珍珠岩12~18份、减水剂10~15份、增稠剂0.7~1份、速凝剂20~25份、胶粉2~3份、纤维30~50份;本发明中提供的3D打印轻质高强混凝土制备方法中采用了表面改性剂对膨胀珍珠岩进行表面改性处理,再对表面改性膨胀珍珠岩经过预湿处理,通过二次搅拌工艺制备出具有优异的施工性能和力学性能的膨胀珍珠岩3D打印轻质高强混凝土。
