Patent holder: Anhui General Institute of Architectural Design and Research Co., Ltd.
The traditional practice of cement mortar protective layers usually does not use crack-resistant materials or a steel wire mesh, but the cost of steel wire mesh is high, making it difficult to control the height of the steel wire mesh in concrete. The invention provides a floor concrete or mortar crack-resistant structure, which uses the tensile strength of the glass fiber net to improve the crack resistance of the concrete or cement mortar by arranging a three-dimensional crack-resistant glass fiber net in the cement mortar layer or concrete layer, thereby improving the overall crack resistance of the protective layer, extending the service life, and reducing maintenance costs.
