In the construction mortar and concrete projects, the common quality problems caused by our factory have been certified and tested for many years, and we have successfully developed the Yulong brand concrete mortar admixture. Its excellent performance fundamentally overcomes the shortcomings of mortar and concrete.
1. Product performance
This product is suitable for concrete and block and various hollow bricks and wall masonry and plastering mortar special supporting products. This product is simple and easy to use during construction. OK, you don’t need to wet the blocks with water. Add the required materials according to the proportion, pour it into the mixer and mix. This product can 100% replace lime and other mortar admixtures. It has good water retention performance, fully hydrates the cement, and improves the quality of mortar and concrete. Strength, the strength is higher after 28 days. Improve the anti-permeability, anti-freeze and durability of mortar and concrete, have good workability and strong bonding force. It can improve the elastic modulus, thermal conductivity and shrinkage value of mortar, thereby achieving a more effective combination with the blocks and making the wall smoother. firm. There will be no explosions, cracks, hollows or peeling when plastering the interior and exterior walls, ensuring the quality of the project.
2. Main technical performance
Performance index of blended mortar:
Project unit index
Strength of blended mortar Mpa 7.5
Compressive strength 7d ≥108 %
28d ≥100%
Weight loss% ≤3%
Performance index of blended concrete:
Project unit index
Concrete strength Mpa 7.5
Concrete bleeding rate % ≤95%
Concrete compression ratio 7d ≥105%
28d ≥100%
3. Use ratio reference
Concrete mortar admixtures account for 10-20% of the cement in the mortar. Accounting for 20% of the cement dosage in the concrete can save 20-30%m3 of cement. Using this product can extend the mixing time by 3 minutes. It can also be adjusted appropriately according to the different grades of mortar and concrete, and the amount of admixtures.
4. Packaging and Storage
This product is double-packed in plastic bags with a weight of 50 kg per bag. Store in a dry and ventilated place to prevent moisture and clumping.
