Liquid crystal polyarylate fiber reinforced concrete and preparation method thereof
The invention discloses liquid crystal polyarylester fiber reinforced concrete and a preparation method thereof. The liquid crystal polyarylester fiber reinforced concrete is prepared from the following raw materials in parts by weight: 200 to 300 parts of cement, 185 to 215 parts of water, 700 to 800 parts of sand, 1000 to 1150 parts of aggregate, 1 to 3 parts of water reducing agent, 100 to 150 parts of fly ash and 0.5 to 5 parts of liquid crystal polyarylester fiber. According to the invention, the liquid crystal polyarylester fiber is used as a reinforcing material to be compounded with the concrete, so that the liquid crystal polyarylester fiber has an excellent promoting effect on crack resistance, low temperature resistance, weather resistance and toughening of the concrete.
本发明公开了一种液晶聚芳酯纤维增强混凝土及其制备方法，所述液晶聚芳酯纤维增强混凝土包括如下重量份的原料：水泥200～300份、水185～215份、砂700～800份、骨料1000～1150份、减水剂1～3份、粉煤灰100～150份以及液晶聚芳酯纤维0.5～5份。本发明将液晶聚芳酯纤维作为增强材料与混凝土复合，对于混凝土的抗裂、耐低温、耐气候性以及增韧具有优异的促进效果。
