Abstract

The invention discloses crack-proof roadside stone and a production process thereof. The crack-proof roadside stone is produced from the following raw materials in parts by weight: 20 to 35 parts of quick lime, 10 to 15 parts of blend fiber, 20 to 35 parts of clay, 30 to 50 parts of coarse sand, 15 to 20 parts of cement, 15 to 30 parts of ceramic waste residue, 10 to 15 parts of fine sand, 9 to 12 parts of pigment, 2 to 8 parts of enhancer and 6 to 10 parts of aid. The invention discloses the crack-proof roadside stone and the production process thereof; the produced roadside stone is high in strength and difficult to crack; by adding the enhancer and the blend fiber, the tensile strength of the roadside stone is improved; by further adding the pigment in the raw materials of the roadside stone, the characteristic of beautifying environment is achieved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an anti-crack roadside stone and a production process thereof. Background technique [0002] The roadside stone is machined and processed by natural granite with uniform texture. The strength of the stone must be qualified. It is required to have uniform color, no cracks on the surface, complete edges and corners, consistent appearance, no obvious spots, color difference, and weathering is not allowed. It has physical properties such as alkali resistance, acid resistance and wear resistance. It is beautiful, durable, large output, small color difference, suitable for various large-scale road laying, etc. Do not drop, smash, bump or touch during loading and unloading to avoid damage. [0003] The output of roadside stone is large, the color difference is small, and it is suitable for laying various large roads. With the ever-changing appearance of the city, beautifyi...
