The wet-mixed mortar is cement, fine aggregate, additives and water, and various components are determined according to the performance. After measuring and mixing in a certain proportion at the mixing station, the mixture is transported to the place of use in a special container for storage, and the wet mix is used within the specified time.
Read MoreAdding hydroxypropyl methylcellulose to cement can slow down the hydration of cement. So what do you know about its principle? Let’s take a look at hydroxypropyl methyl cellulose to delay the hydration of cement. principle.
Read MoreThe viscosity of hydroxypropyl methylcellulose HPMC, which we usually say, refers to the result of its 2% aqueous solution at a temperature of 20 degrees Celsius. The viscosity of hydroxypropyl methyl cellulose is mainly divided into four categories: low viscosity, medium and low viscosity, medium viscosity and high viscosity. Different viscosities have different uses.
Read MoreThe shallow admixture, which plays a key role in improving the performance of building dry-mix mortar, accounts for more than 40% of the material cost in dry-mix mortar. Most additives in the domestic market are supplied by foreign manufacturers, and the reference dosage of products is also provided by the suppliers.
