What are the disadvantages of dry mortar equipment?

1.The technology is not mature. As there is still a lack of complete corresponding specification supply production, construction when using, restricting the promotion of dry mortar equipment in the project. And there is no corresponding technical guarantee to guide the construction, construction technology is not mature, etc. also in varying degrees affect its development.
2, the cost is higher. Due to the high cost of the product, the use of the process in the construction side encountered greater resistance, by the construction side of the current economic interests of the more prominent impact. However, from the comprehensive economic benefits, the material cost of dry mortar can be compensated from saving materials and improving construction efficiency as well as reducing maintenance costs.
3. Mortar varieties are not abundant. Foreign countries have developed more than a thousand varieties of dry mortar, while China is still less than a hundred, so in the use of mortar does not match, does not meet the function of the phenomenon, to the promotion of mortar use to bring extremely adverse effects.
4. Large investment. Dry mortar equipment production line one-time investment is large, the general enterprise can hardly afford, so dry mortar production enterprises are relatively poor. Furthermore, due to the high technical content of dry mortar, the difficulty in using local materials has brought difficulties to the complete promotion of dry mortar.
