With the stricter environmental protection and control policies of various countries and the trend of developing green building materials, ground leveling materials are also being updated, and new materials that replace traditional ground leveling are constantly emerging. Gypsum-based self-leveling mortar is a kind of dry powder self-leveling mortar specially used for ground leveling. It is an ideal material for accurate leveling of building floors and can be used as a bedding base for various types of ground decorative materials. Gypsum-based self-leveling mortar has many advantages as an ideal material.
Preferred material for floor heating backfill
Used as floor heating layer, good thermal insulation performance (floor heating compared with other heating methods, the energy saving range is about 20%. If a separate temperature control device is used, the energy saving can be as high as 40%); it will not crack or bulge due to thermal expansion and contraction like cement mortar layer; in addition, the gypsum-based self-leveling mortar hardened floor has a certain elasticity, foot feeling warm and comfortable; and has a certain sound insulation effect. Gypsum-based self-leveling mortar is superior to traditional cement mortar in strength and thermal stability, and is the preferred material for floor heating systems.
Low shrinkage and excellent crack resistance
Under the same conditions, the shrinkage of cement-based self-leveling mortar is much higher than that of gypsum-based self-leveling mortar, reaching 28d. The shrinkage value of cement-based self-leveling mortar is about 1.17 mm/m. With the extension of time, the shrinkage value of cement-based self-leveling mortar reached about 1.3 mm/m after 90 days, but the shrinkage value of gypsum-based self-leveling mortar remained around 0.19 mm/m. That is to say, in the cement-based self-leveling mortar, the excessively high shrinkage value is very likely to cause the self-leveling mortar to crack. However, the heat resistance of gypsum-based self-leveling at 50 ℃ is basically stable, and the shrinkage values, flexural and compressive strengths of 28d and 194d are almost the same.
Sound insulation, heat preservation, ecological
Gypsum-based self-leveling mortar has low density, which can reduce the bearing quality of buildings, and does not contain harmful substances such as formaldehyde, casein, VOC, and no ammonia gas release. It has significantly improved the environmental protection standards of the entire decoration and is a green and environmentally friendly energy-saving product . The self-leveling construction process has low noise, no sanding, and avoids the generation of dust. Self-leveling also provides a comfortable and quiet use environment, avoiding the noisy sound of footsteps due to uneven ground and the gap left by the keel.
No hollowing, no cracking
The ground constructed with gypsum-based self-leveling mortar has accurate size, extremely high level, no hollowing, and no cracking; it is easy and convenient to operate, high efficiency, and short time-consuming ((it can be stepped onafter 1 day, shortening the decoration period) ; And can use pumping construction, 5-10 times faster than traditional ground material construction speed. The new floor paving process method reduces the thickness and makes your indoor space wider.
The base surface can be used longer
In the process of use, self-leveling is easy to meet the requirements of floor installation, it can provide a stable base surface, the base surface life can reach at least more than 50 years; The leveling accuracy of the ground provided makes the joints in the same plane after the floor is installed, thereby protecting the surface material above and extending the service life of the floor material.
Better visual effect
The self-leveling ground leveling effect is very obvious, which makes the floor paved on the self-leveling surface more beautiful. The flat base ensures that the floor can achieve a mirror-like effect and obtain perfect visual enjoyment; With the promotion of green building materials in various countries, gypsum-based self-leveling mortar will make a big difference in the ground leveling market.
