specific Embodiment approach 1

[0016] Specific implementation method 1: This embodiment is composed of base material lower layer 1 and fabric upper layer 2, the upper layer and the lower layer are firmly combined as one, and the upper layer 2 of fabric is composed of 35-45 parts of colored cement and 55-65 parts of medium sand in parts by weight Composition, the base material lower layer 1 is composed of 5-15 parts of calcium carbide slag, 15-25 parts of cement, 15-20 parts of medium sand, 30-40 parts of crushed stone and 15-20 parts of mineral powder in parts by weight.

specific Embodiment approach 2

[0017] Specific embodiment two: The difference between this embodiment and specific embodiment one is that the upper layer 2 of the fabric is composed of 35 parts by weight of colored cement and 65 parts of medium sand, and the lower layer 1 of the base material is composed of 10 parts by weight of calcium carbide slag, It consists of 25 parts of cement, 15 parts of medium sand, 30 parts of gravel and 20 parts of mineral powder.

specific Embodiment approach 3

[0018] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the upper layer 2 of the fabric is composed of 40 parts of colored cement and 60 parts of medium sand in parts by weight, and the lower layer 1 of the base material is composed of 5 parts of calcium carbide slag, It consists of 20 parts of cement, 20 parts of medium sand, 40 parts of gravel and 15 parts of mineral powder.

Abstract

This invention relates to a calcium carbide slag concrete footpath brick and a process method, in which, the brick is composed of a lower layer of base material and an upper layer of face material, the face layer is composed of color cement 35-45, medium sand 55-65, in terms of weight and the base layer is composed of calcium carbide slag 5-15, cement 15-25, medium sand 15-20, gravels 30-40 and breeze 15-20 according to weight portions, and the process method includes: arranging materials, mixing them, molding and maintaining. The character of the bricks is as follows: 1, weight is reduced and transportation cost is reduced, 2, it is easy to be molded and not easy to generate cracks, 3, the strength and quality of footpath bricks are increased, 4, land is saved and pollution is reduced.

Description

technical field [0001] The invention belongs to building material components. Background technique [0002] Carbide slag is an industrial waste of chemical products. It contains calcium oxide, silicon oxide, iron oxide and aluminum oxide. If it is discarded, it will occupy land and cause serious environmental pollution. Existing pavement bricks made of cement concrete are prone to cracks on the surface of the bricks, and the bricks have problems such as heavy weight, poor strength, and poor physical properties such as flexural resistance. Contents of the invention [0003] In order to solve the problems that cracks are easy to appear on the surface of the existing pavement bricks, the physical properties of the bricks are heavy, poor in strength and flexural resistance, and the carbide slag will occupy the land and cause pollution to the environment if it is discarded, it provides calcium carbide slag concrete. Pavement brick and manufacture method thereof, the technical ...
