Product description
Parameters
1. Features of product use:
1. With the rapid development of the domestic ready-mixed concrete industry, the progress and innovation of concrete has been accelerated, and new technical challenges have also been encountered:
* High durability, extending the life of the building.
*Good stability and pumpability, speed up the construction speed of the project.
*Excellent slump retention performance to avoid illegal operations on site.
* The wide adaptability of raw materials reduces the pressure on quality control in concrete production.
*Optimize concrete mix ratio, reduce energy consumption, and benefit environmental protection.
In the face of these challenges, as the maintainer of the quality of the concrete admixture industry, our unit is committed to the development and production of targeted high-quality products as the development direction, and has successfully developed innovative products that fully meet the high, medium and low strength grades" SJ-53" series products.
2. SJ-53 series products fully use the latest technology, through precise molecular design and various synthesis techniques, so that the molecular structure and properties of water-soluble polymers can be more accurately controlled, and the intermolecular force and space can be obtained. The molecular structure is more perfectly unified, which helps the cement paste to establish a high degree of structure, and maintains quite good homogeneity and stability during the use of fresh concrete, which substantially improves the performance of concrete.
3. The successful preparation of SJ-53 series of polycarboxylate water reducers can help the mixing station to produce concrete with superior performance at a lower cost, effectively save the amount of cementitious materials, and achieve the economy and function of traditional concrete. more reasonable unity.
4. Product features: *Excellent water-reducing and dispersing effect. *Low dosage, high enhancement. *The loss of slump over time is small. *Improve concrete workability. * Improve concrete durability. *No rust to steel bars.
Note: The testing method is in accordance with GB8076-2008 "Concrete Admixtures", the testing dosage is the recommended dosage of the factory, and the testing cement is the benchmark cement.
2. Scope of application and method of use
1. Various Portland cement products.
2. Industrial and civil construction, municipal engineering, water conservancy, transportation and various concrete projects.
3. Prepare high water-reducing, high fluidity, vibration-free self-compacting concrete.
4. The dosage should be based on the requirements of different projects, and the reasonable dosage should be determined through experiments. Generally, the dosage can be adjusted within the range of 0.2~1.0% of the total amount of cementitious materials, and the recommended dosage is 0.2~0.5%.
3. Packaging, storage and transportation
It is packed in 200kg or 1000kg plastic barrels. Storage and transportation should be careful to prevent leakage and keep away from heat sources.
