Dry mortar can greatly improve the engineering quality. Due to constructors' skill level and the quality of cement, sand and other raw materials, the mortar prepared on the construction site often causes buildings' plastering mortar cracking, thus makes the project quality not stable and its strength cannot meet the requirements.
Dry mortar is of highly accurate measurement and reliable quality, which makes it easier to master the matching proportion compared with the traditional process of mortar preparation. Because the mortar for different purposes has different requirements on material properties, such as the properties of anti-shrinkage, anti-cracking, heat preservation, moisture resistance, and so on. These properties only can be achieved by strict preparation in accordance with the scientific formula, and only the production process of dry mortar can meet this requirement.
Dry mortar can totally substitute artificial mechanism sand for natural sand, without any adverse effects to product quality. Some industrial solid waste such as construction waste, coal gangue, steel slag, or even the offcut exploited from the mines and abandoned limestone from the cement tailings, ect., can fulfill the granularity requirements for dry mortar production after crushing and screening. It can not only turn waste into wealth, but also reduce environmental disruption, completely conforming to the concept of developing recycling economy.
The applications of dry mortar, concrete blocks, air-added foam bricks, and other new building materials will greatly improve the demand for gravel crusher and sand making equipment in sandstone industry. As the manufacturers of artificial mechanism sand and gravel equipment, our company has always followed the development trend of sand industry. Through the on-site inspections on dry mortar production and taking a variety of factors occurring in the production course into consideration, our technical staff have upgraded the previous crushers and sand making machines on technology. The adjustable discharging particle size and superior particle shape lay a good foundation for the production of dry mortar.
