Preparation method of prestressed woven fiber reinforced concrete
The invention relates to a preparation method of prestressed woven fiber reinforced concrete. The preparation method comprises the following steps: step 1, prefabricating a three-dimensional fabric: weaving a stitch-knitted fabric of carbon fibers and alkali-resistant glass fibers with organic yarns in a third axial direction; step 2, preparing a concrete component: 40-70 parts of cement; 10-20 parts of alkali-resistant glass fiber chopped yarns; 10-25 parts of quartz sand; 5-15 parts of a silane-based water repellent; 3-8 parts of an allyl ether copolymer; 1-2 parts of the three-dimensional fabric prefabricated in the step 1; step 3, stirring quartz sand, cement, a silane-based water repellent and an allyl ether copolymer into cement mortar; step 4, applying prestress to the three-dimensional fabric, and pouring the mixture obtained in the step 3 on the three-dimensional fabric for forming; and step 5, forming and curing. According to the concrete prepared by the method, the tensile strength is enhanced, the development of cracks is delayed, the rigidity of components is increased, the utilization efficiency and strength of materials are improved, and the deformation resistance of the high-performance glass fiber reinforced concrete thin plate on the high mountain is effectively improved.
一种预应力编织纤维增强型混凝土的制法，该制法包括以下步骤：步骤一、预制三维织物：采用碳纤维和抗碱玻璃纤维的缝编织物以第三轴向的有机纱线进行编制；步骤二、配置混凝土组分：40～70份水泥；10～20份耐碱玻璃纤维短切纱；10～25份石英砂；5～15份硅烷基憎水剂；3～8份丙烯基醚共聚物；1～2份步骤一中预制的三维织物；步骤三、将石英砂、水泥、硅烷基憎水剂、丙烯基醚共聚物搅拌成水泥砂浆；步骤四、对三维织物施加预应力，并将步骤三中所得混合物浇筑在三维织物上进行成型；步骤五、成型养护。通过该方法制成的混凝土增强其抗拉伸强度，延迟了裂缝的开展，增大了构件的刚度，提升了材料的利用效率和强度，有效高山高性能玻璃纤维增强混凝土薄板的抗变形性能。
