High-strength and high-toughness fabricated concrete wallboard and preparation method thereof
The invention discloses a high-strength and high-toughness fabricated concrete wallboard and a preparation method thereof, and the high-strength and high-toughness fabricated concrete wallboard is prepared from the following raw materials in parts by weight: 30-40 parts of 42.5 R ordinary Portland cement, 7-10 parts of S95 mineral powder, 4-8 parts of silica fume, 45-55 parts of quartz sand, 0.5-1 part of steel fibers with the length of 6-8 mm, 0.5-1 part of steel fibers with the length of 10-12 mm, 0.1-0.3 part of a polycarboxylic acid superplasticizer and 0.1-0.3 part of carbon nanotubes. The high-strength and high-toughness fabricated concrete wallboard is provided with metal hanging pieces used for splicing. According to the invention, the short steel fiber and the carbon nanotube material with special dimensions are matched, so that the strength and the toughness of the concrete wallboard are greatly improved, the application problem of a new fabricated building process is solved, and the cost is greatly reduced because the thickness is relatively thin and the whole wallboard is mainly made of a common concrete material.
本发明公开了一种高强高韧装配式混凝土墙板及其制备方法，高强高韧装配式混凝土墙板由以下重量份原料制得：42.5R普通硅酸盐水泥30～40份、S95矿粉7～10份、微硅粉4～8份、石英砂45～55份、6～8mm长的钢纤维0.5～1份、10～12mm长的钢纤维0.5～1份、聚羧酸高效减水剂0.1～0.3份、碳纳米管0.1～0.3份，高强高韧装配式混凝土墙板设有用于拼装的金属挂件。本发明利用两种特殊尺寸规格的短钢纤维和碳纳米管材料的搭配，极大地提高了混凝土墙板的强度和韧性，不但解决了新装配式建筑工艺的应用问题，而且由于厚度比较薄，整体墙板主要还是普通混凝土材料，大大降低了成本。
