Pay attention to ready-mixed Wet-mixed Mortar

[Scott Kaplan]

Now the growth of wet-mixed mortar has dramatically surpassed dry-mixed mortar. Compared with dry-mixed mortar, wet-mixed mortar can reduce drying, dust removal, and on-site vertical tanks. The commercial concrete mixing station has excess capacity and can be put into production after proper transformation. They can produce products according to market needs through trial mixing once they control the quality of sand, gradation, mud content, admixtures, coagulation time, consistency, and strength. Wet-mixed mortar can achieve energy savings, emission reduction, labor saving, trouble saving, and investment savings. The issues that everyone participated in the discussion were: quality control of raw materials, ratio and application of admixtures, and application of wet-mixed mortar.

The emphasis of sand quality control is gradation and mud content. The emphasis of admixture quality control is: setting time, thickening effect, and opening time. The emphasis on selecting water reducing agent, retarder, and thickener, and the application of wet-mixed mortar is the construction method, control of hollowing and cracks. Welcome everyone joins and discuss.

The concrete mixing station for wet-mixed mortar has a natural monopoly, and the cost is low, mainly because of the difficult transportation.

It must be pushed together with mechanical spraying. There is no way to apply it only manually.

A severe defect in the production process of wet-mixed mortar is that the raw material sand cannot be processed!

It is difficult to maintain its mud content and particle grading stable if using the wet river sand. This requires regular sampling testing of incoming raw sand and adjusting the mix ratio, which will bring much extra work! The moisture and mud content of wet sand dramatically influences the grading screening. As far as I know, there is no good screening technology for wet sand. The same is true for machine-made sand.

The biggest advantage of wet-mixed mortar is low cost, and the biggest disadvantage is the problem of storage and quality stability.

There is no problem with the stability of the product. The admixture is already very mature. The admixture is generally used in liquid, which is expensive. There are also powder products that can be used. It is a high-efficiency and stable product!
