Technical performance:
The dosage is 1.0-1.8 of the amount of cementitious material, the water reduction rate can reach 12-25%, the early strength and the enhancement effect are obvious, the strength of concrete 3 days can be increased by 60-130%, the strength of 7 days can be increased by 40-60%, the strength of 28 days can be increased by 20-40%, and the long-term strength is still improved.
Keep the same concrete strength and slump can save 15-20% of cement than concrete without water reducing agent.
The incorporation of this product can greatly improve the workability of concrete, improve the mechanical properties of concrete, so that the compressive, tensile, flexural strength, elastic modulus and long-term strength of concrete have a corresponding increase.
This product has good applicability to all kinds of cement. Such as: Portland cement, ordinary Portland cement, slag cement, pozzolan cement, etc.
ShouldUseScope:
This product is suitable for high strength concrete, fluid concrete, early strength concrete, precast steam curing concrete, prestressed concrete, etc.
This product can be used as a masterbatch, and other components of the compound preparation of different characteristics of the admixture (such as early strength water reducing agent, retarding water reducing agent, pumping waterproofing agent and pumping water reducing agent, etc.), fully meet the requirements of different engineering categories, construction technology, construction technology and temperature conditions.
Method of use：
The powder is calculated as a percentage of the gelding material, the liquid product is converted to the amount of solid content, and the water content is reduced from the ratio.
It is better to use the post-doping method, and the mixing time is appropriately prolonged to facilitate uniformity.
The liquid should be used and stored at a temperature above 15°C to avoid crystallization of sodium sulfate.
When preparing ultra-high strength concrete, the dosage should be increased appropriately.
PackagingStorage and transportation:
Powder products are packed in double-layer plastic and outer woven bags, each bag is 25-40kg, liquid 1000kg/barrel or agreement packaging.
Rainproof and moisture-proof, placed in a ventilated and dry place.
The validity period is three years, and it can continue to be used after passing the concrete performance test.
Safety Guidelines:
This product is non-flammable and explosive. No pollution to the environment, does not contain harmful ingredients that affect human health.
Avoid contact with the skin, must wear gloves, eyes, mask.
If the eye or skin splashes, should immediately rinse with plenty of water, and then immediately seek medical treatment.
After-sales service:
The company has a perfect after-sales service mechanism, at any time to provide users with technical support and on-site service, so that product performance to achieve better results.
