Internal spraying of cement mortar anti-corrosion steel pipe, buried spiral steel pipe, internal and external anti-corrosion

Description :

　　The use of cement mortar is in construction engineering. On one hand, it is used as an adhesive for block masonry materials such as rubble and red bricks in foundation and wall masonry; The second is used for indoor and outdoor plastering. When using cement mortar, certain additives such as foaming agents and waterproofing powders are often added to improve its workability and viscosity. Adding stones in proportion to cement mortar becomes concrete. The strength of cement mortar grade refers to the 28 day age of cubic specimens produced and cured according to standard methods. Usually around 0.6, the proportion actually ignores the composition of water. The mixture of sand and water is called cement mortar. The approximate 1:3 cement mortar refers to the same value in the overall distribution of compressive strength measured using standard testing methods with a mixture of 1 part cement and 3 parts sand. The basic production ratio of water, cement, and sand is 0.6:1:3. Then, the mixed cement mortar is applied to the cleaned inner wall of the pipeline in one or several times according to the design thickness requirements. After a fixed period of curing, a high-strength circular shell lining layer is formed that is tightly bonded to the inner wall of the pipeline.
