The advantages of dry-mixed mortar are mainly reflected in the following aspects:
High-quality products guarantee intensity. It is difficult to prepare all the required raw materials on building construction sites, and the equipment cannot ensure accurate weighing and preparation by the formula requirements. In addition, as the quality of the mortar differs widely, the prepared mortar cannot meet the quality requirements. However, the large-scale automation produced the prefabricated mortar with reliable and stable product quality, and many microchemistry additives ensure product quality and meet special needs.
It can meet the needs of different purposes. Mortars for various purposes, such as masonry mortar, wall mortar, and floor mortar， have additional requirements on the properties of the materials, like anti-shrinkage, anti-cracking, heat preservation, and moisture-proof. In addition, suitability, water-retaining property, and setting time are also different. These characteristics must be selected according to the strict scientific formula requirements.
High production efficiency. The annual output of many dry-mixed mortar production plants in foreign countries is between 300,000 and 500,000 tons, and various dry powder products can meet the market’s needs. Adopting prefabricated dry powder not only dramatically improves the speed of construction but also facilitates construction management to improve the overall level of the modern construction industry. It reduces labor consumption by improving labor productivity, saves raw materials, improves mechanization and automation levels, and dramatically enhances equipment utilization. Also, it improved the quality of buildings and prolonged the service life, saving expenditures in intermediate links, such as saving yard rental fees for sandstone, storage materials, and cement packaging bags. More importantly, it sped up construction progress and held expenses, promoted the development of the cement industry and new technologies for concrete, and promoted the construction industry to develop in the direction of industrialization.
Good environmental benefits. Since the problem of environmental pollution has seriously threatened the survival and health of human beings, people pay more and more attention to environmental protection. The application of dry-mixed mortar has significant benefits for environment. First, since various raw materials do not need to be piled up on site, it avoids ecological pollution caused by materials during transportation and stacking and eliminates the phenomenon of dirty and chaotic construction sites. Secondly, it removes the noise caused by on-site mixing, dust, sewage, and other pollution phenomena, improving people’s working and living environment and facilitating civilized construction. Large-scale centralized production of dry-mixed mortar not only has low loss and less waste but also can use industrial waste, such as fly ash, to turn waste into treasure and become a “eco-friendly building material” in a certain sense, like floor mortar. The quantitative packaging of dry-mixed mortar is convenient for transportation and storage. The construction unit can purchase quantitatively according to the needs, saving raw materials and facilitating construction management. There are no piles of raw materials on the construction site, reducing the impact on the surrounding construction environment.
