The problems in the development process of dry mortar

According to the current our country development in terms of dry mortar, the defects in the following several aspects. 1, the cost is higher. Because of the cost of the product, in use process encountered in construction of large resistance, affected by the contractor's current economic interests. But from the point of comprehensive economic benefits, dry mortar materials costs can be from save material and improve the construction efficiency and reduce maintenance costs make up for. 2, the technology is immature. Due to the lack of corresponding specification of complete supply production, construction, restricting the promotion of the dry powder mortar in engineering. And there is no corresponding technical support to guide construction, construction technology is not yet mature, also in different degrees of influence its development. 3, mortar varieties is not rich. Abroad has developed more than one thousand kinds of varieties of dry mortar, while our country is less than one hundred kinds, therefore in use, the phenomenon of the mortar don't match, does not meet the function, to promote the use of mortar very adverse impact. 4, large investment. Dry mortar production line of one-time investment, general enterprise unbearable, so dry mortar production enterprises is relatively poor. Moreover, as a result of dry mortar of high technical content, has certain difficulty in the use of local materials, bring difficulties in popularization of dry mortar.
