Reinforced cement material prepared from solid waste mixture and preparation method

Abstract

The invention relates to the technical field of cement preparation, and further discloses a reinforced cement material prepared from a solid waste mixture. The reinforced cement material is prepared from, by weight: 45 to 60 parts of Portland cement, 20 to 40 parts of natural quartzite, 1 to 3 parts of a water reducing agent, 10 to 25 parts of the solid waste mixture, 4 to 8 parts of alkali-resistant glass fiber and 10 to 25 parts of water. A preparation method of the reinforced cement material prepared from the solid waste mixture comprises the following steps: 1, selecting raw materials; 2,mixing the raw materials; and 3, adopting a mechanical spraying process. According to the reinforced cement material prepared from the solid waste mixture and the preparation method, the purity of theprepared raw materials is relatively high, and various properties of cement are improved.

Description

technical field [0001] The invention relates to the technical field of cement preparation, in particular to a reinforced cement material prepared by using a solid waste mixture and a preparation method. Background technique [0002] Cement is made of limestone and clay as the main raw materials, which are crushed, batched, and ground to make raw material, and then fed into the cement kiln to calcinate the clinker, and then the clinker is ground with an appropriate amount of gypsum, mixed materials, and additives. Cement is widely used in civil engineering, water conservancy, national defense and other projects. [0003] Waste concrete particles and waste brick particles are both construction solid wastes, which are solid wastes generated when buildings are demolished due to reaching the end of their service life or due to aging. Compared with concrete, the strength of bricks is very low, and the water absorption rate is high. After concrete and bricks are mixed, the crushin...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a reinforced cement material prepared by using a solid waste mixture and a preparation method, which has the advantages of high purity of the prepared raw materials and improved performance in various aspects of the cement, and solves the current problems in preparation and selection. When using raw materials, the processing process is relatively simple, so the purity of the obtained raw materials is not high, which reduces the quality of the material, and finally reduces the performance of various aspects of the cement.
