Dry mortar is a mixture of a variety of raw materials, according to a certain formula in the factory with dry mixing, the site only need to add water mixture can be used in the mixture. Dry mortar in foreign countries has been widely used in the country with the improvement of building quality requirements, to develop new building materials, green building materials have been incorporated into China's development plan.
Use of dry mortar Advantages:
1) high quality products. According to the different uses of mortar such as masonry, plastering and the ground, the anti-shrinkage, anti-cracking, waterproof, insulation and other characteristics of different requirements, mortar needs in accordance with the different formulations can be achieved through strict preparation. In the actual construction, due to the quality of all raw materials, the correct mix, mixed uniformity can not be guaranteed, often resulting in the quality of mortar instability. The use of large-scale automation of professional production line production of dry mortar, reliable quality and stability, and can produce a variety of special applications to meet the needs of special dry mortar.
2) high production efficiency. Dry powder mortar production plant production scale, the annual output is usually about tens of tons, you can have a variety of dry powder mortar series of products to meet market demand. The use of dry mortar is also conducive to the modernization of construction equipment to promote the use of construction to reduce the duration of construction.
3) less environmental pollution. Large-scale centralized production, the use of premixed and bag packaging, easy to construction, transportation and storage, to avoid the construction site accumulation of raw materials and on-site mixing of the surrounding environment.
Dry powder mortar shortcomings:
Dry powder mortar products, there are some performance defects, such as mortar products can easily produce cracks to make natural water leakage to reduce the durability of the building, mortar products, low temperature flexibility, tensile strength, impact resistance and so on.
How to overcome the performance of dry powder mortar above it?
The current method of adding fiber is more common. Among them, the use of polypropylene fiber can improve the performance of mortar defects, polypropylene fiber in the mortar in a good uniform to the three-dimensional step, the use of polypropylene fiber good ductility, adhesion, transmission stress, absorption of energy to suppress Mortar due to cement dehydration shrinkage (shrinkage), cement hydration caused by internal and external temperature difference (temperature shrinkage), cement hydration process volume deformation (chemical shrinkage) and other factors caused by micro-crack, thereby improving the integrity of mortar, flexibility , Continuity, as well as cracking, impermeability and tensile strength.
The slightest message
In the project by adding polypropylene fiber, can significantly improve the mortar and external wall insulation board crack resistance, improve the integrity of the external wall insulation system can ensure that the thermal insulation material and the wall of the common role and effectively block the thermal bridge, Improve the mortar, insulation board easy to work; especially for the outer layer of insulation board mortar, adding fiber can improve the mortar surface resistance to temperature and humidity changes, the impact of wind and rain, increasing the overall stability of the outer insulation layer, to overcome the outside the wall Insulation layer of the durability is not good, easy to produce dry shrinkage cracks, complex construction process and other shortcomings.
Jiangsu Silk Fiber Co., Ltd. Tips: Polypropylene fiber can only be used as a secondary reinforcement, can not replace the structural strengthening materials (such as reinforced steel), not alone used to solve the settlement and by the impact of strong external shock cracking occasions , Not because of the use of fiber and reduce the size of the main structure, the use of fiber construction and conservation should be strictly in accordance with the relevant provisions of the state and practice.
