Dry mixed mortar is also called dry mortar, usually called hydraulic cement mixed mortar. It refers to aggregates, inorganic cementitious materials and additives that have been dried and screened in a certain proportion. A kind of granular or powdery material that is physically mixed and transported to the construction site in bags or bulk. It can be used directly after being mixed with water. Dry mortar plays the role of bonding, lining, protection and decoration in thin layers in the construction industry, and is widely used in construction and decoration projects.
Wet-mix mortar refers to cementitious materials, fine aggregates, admixtures and water, as well as various components determined based on performance, in a certain proportion, in the mixing station After being measured and mixed, the mortar mixture is transported to the place of use by a mixer truck, stored in a special container, and used within the specified time. The working principle of wet-mix mortar is similar to that of commercial concrete. The commercial concrete mixing station can produce wet-mix mortar at the same time.
Advantages of lightweight lightweight gypsum mortar dry mixing:
1. Stable and reliable quality , can meet different functional and performance requirements and improve project quality.
2. Improved efficiency is conducive to the application of automated construction machinery and tools, changing the backward methods of traditional building construction.
3. It has strong adaptability to new wall materials and is conducive to the promotion and application of new wall materials.
4. Easy to use and easy to manage.
Advantages of wet-mixed lightweight gypsum mortar:
1. Wet-mixed mortar It can be used directly after being transported to the site without processing, but the mortar must be stored in a closed container.
2. Wet-mix mortar is prepared in a professional production plant, which is conducive to ensuring and controlling the quality of the mortar.
3. Wet-mix mortar has a large selection of raw materials. In addition, a large amount of artificial waste materials made from industrial solid wastes such as industrial waste slag, steel slag, and industrial tailings can be used. Machine sand not only saves resources, but also reduces mortar costs.
4. The construction site has a good environment and less pollution.
Storage methods of wet-mixed lightweight gypsum mortar:
Different varieties and strengths Wet-mix mortars of different grades should be stored in different storage containers, and the storage containers should be labeled. The labeling should include the type, strength level, and use time limit of the mortar. Mortar should be stored first and used first. Water should not be added to wet mortar during storage and use. During the storage of mortar, when a small amount of bleeding occurs, it should be mixed evenly before use. After mortar is used up, its storage container should be cleaned immediately.
Storage methods of dry-mixed lightweight gypsum mortar:
Different varieties of bulk Dry-mix mortars should be stored separately in bulk mobile silos and should not be mixed and mixed, and the silos should be marked. The number of silos should meet the mortar variety and construction requirements. When changing mortar types, the silo should be emptied. The silo should comply with the current industry standard SB/T10461-2008 "Dry Mix Mortar Bulk Mobile Silo" and should be installed firmly on site. Bagged dry-mix mortar should be stored in a dry, ventilated, moisture-proof, and rain-proof place, and should be stacked separately according to type and batch number. Mixed piles are not allowed and should be stored first and used first. The organic materials in the supporting components should be stored in a cool, dry, ventilated place, away from fire and heat sources. They should not be stored in the open air or exposed to the sun. The storage environment temperature should be 5℃~35℃. </p
