Green Development of New Building Materials

At the beginning of the new century, the common thing in China's construction sites is the roar of machines, dust all over the sky, pedestrians cover their noses and pass quickly; conditional construction sites, constantly spraying water to wash the ground, its human and material resources investment is considerable. This problem has also attracted domestic attention, how to find a simple, environmentally friendly building materials application road. There are still many problems to be solved. With the newBuilding Materialsgreen development and sustainable development of the construction industry has become a topic of widespread concern.
Dry-mixed mortar refers to a granular or powdery material made by physical mixing of aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) in a certain proportion, which is transported to the site in the form of bags or bulk, and can be used directly after mixing with water. It can efficiently play the role of masonry, bonding, padding, protection and decoration in the construction industry, and is widely used in construction and decoration engineering. Building to become green, first of all to reduce energy consumption, reduce energy consumption is the best way to make the wall insulation performance is superior. Now, the aesthetic requirements of the house are getting higher and higher. To stick the tile veneer, you have to find a suitable adhesive. It is best to realize factory production, and you can use it when you mix it with water on site.
The components of dry mixed mortar vary from 3 to more than 20. But the most basic are containing cementitious materials, aggregates and admixtures. Cementitious materials include inorganic cementitious materials such as cement, lime, gypsum, etc., organic cementitious materials have dispersed latex powder and water-soluble polyvinyl alcohol, etc., aggregates include natural sand and artificial sand, mineral admixtures such as fly ash, silica fume, slag powder, limestone powder, etc., chemical admixtures such as cellulose ether, starch ether, coagulant, water reducer, air entraining agent, etc. The performance of dry mixed mortar mainly depends on its composition, inorganic (organic) cementitious material mainly plays a cementing role; aggregate plays a skeleton role (sometimes highlights the decorative effect), mineral admixtures improve the workability of mortar, both of which play an important role in volume stability; chemical admixtures improve the physical properties of mortar, and also play an important role in the performance of mortar after hardening. Inorganic insulation mortar insulation system and its supporting mortar, insulation board insulation system adhesive, plaster mortar and decorative mortar, high-quality interface treatment agent, tile adhesive, caulking agent, waterproof mortar, self-leveling mortar, repair mortar, grouting material, putty for internal and external walls, as well as special masonry mortar and plastering mortar and other products. The mechanism of action of polymer materials such as cellulose ether and redispersible latex powder in dry-mixed mortar has laid a theoretical foundation for the research and development of dry-mixed mortar products and technologies. The relationship between the five elements of material composition (structure), preparation process, performance, use efficiency and environmental coordination of a series of dry-mixed mortar has been established, which provides a scientific basis for system development and green production.
The construction industry is one of the indispensable industries in our life, and its green development will provide a better living environment for our life.
