Description

technical field [0001] The invention belongs to the field of cement, and in particular relates to a novel masonry cement. Background technique [0002] Masonry cement is mainly used for masonry and plastering mortar and cushion concrete, and its conventional components are mixed materials, Portland cement clinker and gypsum. Due to the lack of water retention of traditional masonry cement, wet water treatment (also known as wet construction) must be performed on new wall materials before construction. Because wet water treatment will increase the moisture content of new wall materials, on the one hand, it will cause the inner wall to be damaged. It is easy to condense and be damp and moldy. On the other hand, it will increase the shrinkage value of the new wall material, which will lead to cracking and hollowing of the plastering mortar. [0003] Because the existing masonry cement has the above-mentioned shortcomings, ordinary portland cement is often used in engineering t...

Problems solved by technology

However, the price of these admixtures is usually high, and the amount of admixtures is small, and it is difficult to ensure the accuracy of the amount of admixtures in the method of adding admixtures on the construction site; in addition, there may be compatibility problems between admixtures and cement. The existence of problems makes it difficult for special admixtures to be widely applied

Since ordinary Portland cement is still used, it does not meet the requirements of sustainable development
