Study On Fabrics' Reinforcing Function To Wall

Constructions made of grout or concrete always appears to cracks. Studies on fiber-reinforced grout or concrete are very popular, especially, fabrics whose effects are more visible can reduce direction limit of fiber.In terms of fabric density, layers and geometry, the text discusses effects on strength of grout or concrete which the fabrics take. Manufacture leno woven, one-lay, two-layer, four-layer planar fabrics and cross-shaped fabrics; make grout or concrete specimens; measure tensile strength and curve strength of fabric-reinforced grout or concrete; study the fabrics'reinforcing functions to the wall rendering surface and the wall configuration.The studies of wall rendering with fabric says: fabric is better than fiber; bigger the fabric density is, bigger the strength of grout or concrete is. The warp density of from fifty per ten centimeters to sixty is suitable; more the fabric layers are, bigger the strength is, but the layer shouldn't be so many. The layer from 3 to 4 in 3- centimeter-thick grout is good; The place of fabric in specimen will affect the strength.The studies of wall configuration say: fabric structure takes effects on tensile strength and curve strength of fabric-reinforced concrete. Cross-shaped fabrics take better function than planar fabrics do.
