Glass fiber reinforced concrete and preparation method thereof
The invention relates to the technical field of building materials, in particular to glass fiber reinforced concrete and a preparation method thereof. The glass fiber reinforced concrete comprises the following raw materials in parts by weight: 40 to 70 parts of cement, 10 to 20 parts of alkali-resistant glass fiber chopped yarns, 10 to 25 parts of quartz sand, 5 to 15 parts of a silane-based water repellent, 3 to 8 parts of an allyl ether copolymer and 1 to 2 parts of a three-dimensional fabric. The three-dimensional fabric is added, so the reinforcing effect in the direction of thickness is increased, bending resistance can be exerted in all directions, cracks caused by stress concentration are avoided, and the mechanical property and durability of the concrete are further improved.
本发明涉及一种建筑材料技术领域，特别涉及玻璃纤维增强混凝土及其制备方法。所述玻璃纤维增强混凝土包括以下重量份数的原料：水泥40份‑70份；耐碱玻璃纤维短切纱10份‑20份；石英砂10份‑25份；硅烷基憎水剂5‑15份；丙烯基醚共聚物3‑8份；三维织物1‑2份。加入三维织物，三维织物增加了在厚度方面的增强作用，能够全方位发挥抗弯性能，避免出现应力集中而出现的裂纹的产生，还有利于进一步提高混凝土的力学性能和耐久性。
