With the continuous improvement of engineering quality, environmental protection requirements and civilized construction requirements, the shortcomings and limitations of mixed mortar in the construction site are more and more prominent, and dry mixed mortar because of its advantages in technical performance, social benefits and other aspects of more and more people's favor.
1. Production quality is guaranteed
Dry mixed mortar has a professional manufacturer production, a fixed place, a complete set of equipment, accurate measurement, a perfect quality control system. Such as perfect computer control system to ensure the entire production process accurate and stable. The drying of river sand controls the water content of the sand (the general requirement is ≤0.5%), the dust removal controls the mud content of the sand (the general requirement is ≤0.5%), and the screening controls the grading (the grain size of the sand required by the general production is less than 2.5mm, and it is divided into several intervals respectively stored, and then the reasonable grading is carried out according to the product requirements in the production). Accurate computerized measurement ensures the accuracy of raw material weighing. The forced mechanical mixing ensures that the materials are evenly mixed. The standard and strict quality inspection makes the product quality balanced. Such a variety of measures, fully ensure the quality of products.
2. Construction performance and quality is superior
Mortar according to the product type and performance requirements, specific design mix ratio and add a variety of additives for modification, such as commonly used additives cellulose ether, redispersible emulsion powder, thixotropic lubricant, defoaming agent, air entraining agent, coagulant, hydrophobic agent. Modified mortar has excellent construction performance and quality, good workability is convenient for masonry, plastering and pumping, improve construction efficiency, such as manual batching plastering 10m2/h, mechanical construction 40m2/h; The length of a slurry is greatly increased during masonry. Because of its excellent construction performance and quality, the construction quality is improved, the thickness of the construction layer is reduced, and the material is saved. Improved construction quality reduces the opportunity for repair and rework and reduces the long-term maintenance costs of the building.
3. A complete range of products to meet a variety of different engineering requirements
Dry-mixed mortar manufacturers can design formulas according to different matrix materials and functional requirements, such as high water-retaining masonry and plastering mortar designed for various wall materials with large water absorption, such as aerated concrete blocks, gray sand bricks, ceramsite hollow blocks, fly ash bricks, etc. It is used for the artesian flat mortar which requires high flatness. Can also meet a variety of functional requirements, such as insulation, impermeability, grouting, repair, decoration, etc. According to incomplete statistics, there are more than 50 kinds of dry mortar.
4. High - quality environmental - friendly materials have obvious social benefits
One of the dry mixed mortar is the factory ready mix material, just add water to stir evenly can be used at the site, and dust is very little, more environmental protection. Second, because of its excellent construction quality, will greatly increase the confidence of contractors and owners, such as the original in Guangzhou citizens have a saying "tigers are not afraid, afraid of leakage", so it can be seen that the leakage of traditional mortar waterproof layer is also a prominent problem that puzzles owners, and dry mortar in a variety of characteristics of waterproof material will fundamentally solve such problems, On July 25, 2002, Guangdong Construction Daily published an article entitled "dry mortar to put on the wall" waterproof ", which can also see the extent of social attention to such issues. Three because of its excellent operation performance, construction speed, low labor intensity, less dust on the site, the advantageous worker health, more in line with our "people-oriented" purpose. The fourth is accord with our country develop bulk cement. Take Guangzhou as an example: in the 5 years since 1999, the growth rate of divergence in Guangzhou has increased greatly every year. The popularization and popularization of dry mixed mortar will be conducive to the further improvement of bulk cement.
