Abstract

The invention discloses an anti-corrosion and heat-insulating cement. The anti-corrosion and heat-insulating cement is prepared from the following raw materials in parts by weight: 40-80 parts of cement clinker, 5-10 parts of gypsum, 10-15 parts of fly ash, 3-7 parts of waste incineration ash, and 20-30 parts of powdery mixture, wherein the powdery mixture consists of the following components in parts by weight: 45-50 parts of magnesium oxide, 10-15 parts of calcium carbide, 15-20 parts of silicon carbide, 10-20 parts of calcium oxide, and 1-5 parts of iron oxide. According to the anti-corrosion and heat-insulating cement, the mixture of the magnesium oxide, the calcium carbide, the silicon carbide, the calcium oxide and the iron oxide is added into traditional cement production raw materials, so that the produced cement has the characteristics of high temperature resistance, anti-corrosion and freeze resistance, and the service life of the cement is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to an anti-corrosion and heat-insulating cement. Background technique [0002] Cement: powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. For a long time, as an important gel material, it is widely used in civil construction, water conservancy, national defense and other projects, and is an indispensable material in the construction industry. Existing cements have limited strength. The setting and hardening speed is slow, and the frost resistance and heat resistance are relatively poor. Moreover, in the later maintenance, more attention should be paid to the influence of various erosions, and the corrosion resistance is also poor, which greatly shortens the service life of cement.
