Dry mortar development prospects

Although dry mortar meet a variety of resistance in promotion in use process, but the historical inevitability of its instead of traditional mortar is difficult to change. Not only in Shanghai and other large and medium-sized cities have great interest to the use of dry powder mortar, the deepening of the media publicity, many workers for science and technology progress of science and technology will create favorable conditions for the development of dry mortar. As the development of commercial concrete, it will usher in a bright spring. From the developing trend of the current and future development in the dry mortar in China mainly concentrated in the following: 1, the use of industrial waste and local materials as the main raw material of dry mortar varieties. Fly ash, slag and waste stone powder, the use of the refining slag, bentonite, etc, can not only reduce the cost of dry mortar, improve the performance, but also to protect the environment and save resources. 2, the development of new varieties. Only to develop comprehensive, in line with market needs, all kinds of mortar, can make its use scope is not restricted, create favorable conditions for the smooth promotion. With the emergence of special mortar, special mortar not only promote the development of dry mortar, also create conditions to promote the development of other industries. 3, to develop their own production process. The dry mortar production technology in our country is not yet mature, general production enterprise production line imported from abroad, the investment of a production line is in commonly 2000 ~ 30 million yuan, the price is high. Only production technology developed in accordance with China's national conditions, to create conditions for the comprehensive construction of dry powder mortar enterprises, not only reduces the cost of investment, and reducing the production costs. 4, in harmony with the wall materials. Countries have been working to promote the use of new wall materials, so the developed and the current main use of bulk materials matching dedicated mortar is a must. According to relevant data show that the original slurry concentration in the process of using new type wall materials exhibit problems are: a, mortar construction performance is bad, block bibulous too much and in the process of masonry block water loss in the process of drying occurred secondary drying shrinkage result in the crack of the walls; Mortar masonry is not full, such as hollow quality problems. B, mortar in dry cured adhesive power in the new type wall materials with different section size and clay brick, the phenomenon of the cohesive force is insufficient, lead to the wall under the influence of deformation and stress cracking.

dry mortar in the development of our country is a new things, there are a lot of work to do, is not only a technical problem, and why people thought. To eliminate the obstacle of the development path of dry mortar, also need to state on the policy, economy with great support and help. Only under the various aspects of a concerted effort to work, to promote the progress of the whole building technology, dry mortar can truly healthy development road.
