Shandong chuangyao biotechnology analyzes the difference between wet mixed mortar and dry mixed mortar

At present, the production of mortar also has different forms. Some can be mixed in the mixing station and sent to the construction site, while others can be used with bagged dry mixed mortar directly by adding water. What are the differences between the two?

① Mortar state and storage time are different

Generally, wet mixed mortar is a kind of wet mixed material composed of raw materials and directly mixed with water. It is directly used in the construction site without adding water, but it should be used before the mortar sets. The storage time is not more than 24h, and the operation time is relatively short.

Dry mixed mortar is a kind of dry mixed mixture, which can mix materials evenly in bulk or in bags. It can be used after directly adding water to the construction site. Due to the addition of hydroxypropyl methylcellulose and redispersible latex powder, the storage period of dry mixed mortar is longer, usually 3 months or 6 months, and the operation time can also be extended.

② Different production equipment

At present, the wet mixing mortar production and processing plant is specialized in the production of dry mixing mortar.

③ Different varieties Because the wet mixed mortar adopts the form of wet mixing, which is not suitable for producing high viscosity mortar, there are very few varieties of mortar, only masonry, plastering, ground and other varieties; while the dry mixed mortar produces dry materials, which is not interfered by the mode of production. Different additives can be added to dry mixed mortar to change the characteristics of mortar, such as adding flexible redispersible emulsion powder, which will make the mortar stable The change has flexibility and ductility, adding adhesive redispersible latex powder and hydroxypropyl methylcellulose will make the mortar better adhesion and strength, adding hydrophobic agent and early strength agent can also change the characteristics of mortar, so there are many kinds of dry mixed mortar.

④ Different sand treatment methods

The sand for wet mixed mortar does not need to be dried, while the sand for dry mixed mortar needs to be dried.

⑤ Transportation equipment is also different

The wet mixed mortar is transported by mixer truck, which can ensure that the mortar will not be layered and separated during transportation; the bulk dry mixed mortar is transported by tank truck, and the bagged dry mixed mortar is transported by truck, which is convenient and fast.

Therefore, we can find that both wet mixed mortar and dry mixed mortar have their advantages and disadvantages, so we should choose according to the actual situation, otherwise it will increase the cost. However, with the rise of green building materials, dry mixed mortar will be more green, more mortar information please log in Shandong chuangyao biotechnology http://www.cyhuagong.com/
