The dry mortar is processed by dry sieving aggregate (such as quartz sand), inorganic cementations materials (cement) and additives (such as polymers) by a certain percentage of the physical mixture of a granular or powder form of transport to the site in bags or bulk materials, add water, mixing can be used directly. Also known as the mortar dry powder, dry mixing, dry mixing powder and some construction adhesive is also belongs to this category. Dry mortar in the construction industry play in thin-layer bonding, pads, and protective and decorative, construction and renovation works extremely wide application. Dry mortar powder tile adhesives, dry wall paint, dry wall mortar, dry concrete.
Dry mortar originated in Austria and Finland. With the wall material product quality continues to improve and enhance, the wall of the walls more and more flat, and no longer need to apply a thick layer of mortar came just a thin mortar can meet the purpose of the wall plastering, rather -site mixing is difficult to produce a thin layer of mortar. 1958, a company in Finland started to develop the dry mortar products for the thin layer of mortar to begin production in 1961, during which Germany started the production of dry mortar. Currently, annual production of dry mortar is nearly one hundred million tons, Europe produced about 50 million a year T-, of which Germany accounted for one quarter. China's cement production accounts for 40% of the world, only 1% of the world's dry mortar.
Dry mortar as a "green" new building materials, high quality, low cost, safety and environmental protection features, not only improve the utilization of cement, and reduce the use of the same amount of cement, reducing the construction cost, with an alternative to traditional mortar The function of the additive.
In order to encourage the promotion and application of the dry mortar admixture, China introduced the policy and regulations of the cement industry development special planning "Cement Industry Development Policy" and "dry mortar production and application of technical regulations".
2007, in order to reduce the polluting countries it mandatory for construction sites must use dry mortar. This means that you can not separate the purchase of sand and cement, can only be purchased individually packaged dry mortar. Foreign mature markets, demand for dry mortar should be in more than 200 million tons, while the actual dry mortar production of only 6.4 million tons. In addition, according to the 2007 China's cement industry analysis and investment consultation report, as China's industrialization and urbanization accelerated, and new rural construction steady implementation of the basic raw materials for the next 20 years, cement and other construction projects, will remain more high demand. This means that this industry there is a huge gap in the market!
