Abstract

The invention relates to the technical field of concrete, and provides a compound concrete and a preparation method thereof, wherein the compound concrete is high in strength, good in crack-resisting effect, excellent in anti-bending performance, strong in freezing resistance, resistant to corrosion and low in cost. The compound concrete comprises the following raw materials in parts by weight: 70 to 80 parts of water, 150 to 160 parts of cement, 490 to 500 parts of recycled coarse aggregate with the particle diameter between 5 and 40mm, 180 to 190 parts of recycled fine aggregate with the particle diameter between 0.15 and 4.75mm, 65 to 75 parts of stone slurry powder, 1 to 3 parts of fluidizer, 5 to 15 parts of water glass and 3 to 7 parts of ethylene polypropylene monofilament fibers. The preparation method comprises the following steps: (1) preparing the recycled coarse aggregate and the recycled fine aggregate; (2) preparing the stone slurry powder; and (3) stirring the mixed raw materials.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a composite concrete and a preparation method thereof. Background technique [0002] Due to the development of the economy and the rise of the real estate industry, the society's demand for all kinds of stone slabs has expanded rapidly. In coastal and inland areas rich in ore resources, stone enterprises are developing in the direction of clustering and scale. Similarly, due to the extensive use of resources Due to the profit-seeking nature of capital, stone companies allow the discharge of a large amount of stone waste (mainly cutting and crushing scraps, and stone slurry produced by grinding), resulting in large-scale soil desertification, ecological damage, and more wind and sand. , environmental pollution, etc., seriously affecting production, life and social and economic development. [0003] On the other hand, the production of large cement in concrete, the cement industr...
