Abstract

The invention relates to cement, which comprises the following components by weight: 50-100g of 80# cement, 20-30g of silica sand powder, 5-10g of diatomite powder, 10-15g of barium sulfate powder, 3-8g of OP-10 emulsifier and 5-10g of sodium phosphate, wherein the granularities of 20-30g of silica sand powder and 5-10g of diatomite powder are respectively 100-300 micrometers. The preparation method of the cement comprises the following steps of: 1, taking the components by weight for later use; 2, uniformly mixing the 80# cement, the silica sand powder and the diatomite powder to obtain a mixture, and grinding the mixture to reach the granularity of 50-100 micrometers in an air-current mill; 3, adding the barium sulfate powder, the OP-10 emulsifier and the sodium phosphate into the ground material, and stirring for 10-20 minutes in a stirrer. The cement is excellent in waterproofness and can be used for improving the performance of cement paste with higher water content by using a material consisting of phosphate and mineral substances; the cement is especially suitable for being used during waterproof operation to small gaps; and the cement paste is good in paste stability and quick to harden.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a cement and a preparation method thereof. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It can be hardened in air or water after being stirred with water to form a slurry. It is used to cement sand, stone and other granular materials into mortar or concrete. [0003] At present, the ones used in places with serious water seepage often have the disadvantage of poor anti-seepage effect, especially when waterproofing small gaps. Contents of the invention [0004] One object of the present invention is to provide a kind of cement. Another object of the present invention is to provide a preparation method of cement. The cement has fine texture and good waterproof effect. The preparation method has simple steps and is safe and environment-friendly. [0005] The technical solutions adopted are: [0006] A cement comprising 50-100g of No. 80 cement,...
