Zusammenfassung: | 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 |
