Fireproof composite cement mortar

Abstract

The invention discloses fireproof composite cement mortar. The fireproof composite cement mortar is characterized by being prepared from the following components: 30 to 50 parts of talcum powder, 70 to 100 parts of cement, 40 to 60 parts of ground quartz, 60 to 120 parts of iron-titanium powder, 5 to 10 parts of gas-phase silicon dioxide, 3 to 8 parts of pentaerythritol, 70 to 80 parts of aerated concrete particle, 15 to 25 parts of calcium hydrogen carbonate, 4 to 10 parts of bentonite, 0.2 to 1.0 part of cellulose, 3 to 5 parts of sodium tripolyphosphate, 5 to 10 parts of pottery clay, 10 to 20 parts of dichloroethane and 10 to 30 parts of ultrafine calcium carbonate. When the fireproof composite cement mortar is used, all the components are added according to a ratio, and proper amount of water is added and uniformly stirred with the components; then a mixture can be used for constructing. Compared with the prior art, the fireproof composite cement mortar has the advantages of easiness of formation, light weight, good fireproof performance and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an easy-to-form and light-weight fireproof composite cement mortar. Background technique [0002] When traditional cement mortar is used as an exterior wall building, it is prone to problems such as poor fire resistance, hollowing, and cracking, and it is heavy as a building material on the surface of the wall, which increases the overall weight of the building. The density of composite building materials currently on the market is low. After the completion, the anti-cracking effect is not obvious, and the strength of the cement mortar is low, and the texture is relatively loose, which easily affects the overall stability of the building. Contents of the invention [0003] Aiming at the shortcomings and deficiencies of the prior art, the invention proposes an easy-to-form, light-weight fireproof composite cement mortar. [0004] The present invention can reach throu...
