Abstract

The invention relates to a fiber fabric cured-finished concrete member and a preparation method thereof. The preparation method comprises the following steps: firstly, weaving and moulding fiber fabric; secondly, laying the fabric on the moulding surface of a moulding plate, and manufacturing the moulding plate according to a required member shape; thirdly, pouring concrete, wherein the hooked surface of the fiber fabric can be in full contact with the concrete; finally, demoulding after final set of the concrete to obtain the fiber fabric cured-finished concrete, wherein the fiber fabric is firmly adhered to the surface of the member. According to the preparation method, moulding, curing and finishing of the concrete are completed once, a good curing effect on the concrete on the surface layer is achieved, the early strength and the crack resistance of the concrete can be significantly improved, and a requirement on the surface quality of the moulding plate is lowered; in addition, in the using process, the fabric material can further show the advantage of using comfort, such as good sound absorption and heat insulation, and due to water absorption and water release performance of the fabric material, indoor air humidity also can be regulated.

Description

technical field [0001] The invention relates to a fiber fabric maintenance-decoration concrete component and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry, the demand for cast-in-place concrete and precast concrete components is increasing. In addition to the requirements for project quality and construction speed, people have begun to pay more attention to energy saving and environmental friendliness of building construction. [0003] Concrete pouring construction, maintenance, and later surface decoration are the two main processes of concrete buildings, which determine the quality and visual effects of buildings, and are also key links in consuming resources and energy. The maintenance technology has a great influence on the performance of concrete. The concrete material needs reasonable maintenance after pouring to achieve the expected mechanical strength and durability. At present, the commonly used...
