Water reducer refers to the concrete workability and cement dosage under the same conditions, can reduce the mixing water consumption, improve the strength of concrete;
Or in the workability and strength of the same condition, save the amount of cement additives.
Use water-reducing agent should comply with what technical requirements, follow below small make up to see together.
1. The powder is calculated according to the percentage of cementing material, and the liquid product is calculated according to the amount of solid.
2. After mixing method is better, appropriately extend the mixing time to facilitate the uniformity.
3. The liquid should be used and stored at a temperature above 15℃ to avoid sodium sulfate crystallization.
4. The content is 0.5-1.0 of the dosage of cementitious material, the water reduction rate can reach 12-20%, the effect of early strength and enhancement is obvious, the strength of concrete increases 60-130% in 3 days, 40-60% in 7 days, 20-40% in 28 days, and the long-term strength is still improved.
5. The concrete with the same strength and slump can save 15-20% of cement compared with the concrete without water reducing agent.
6. The incorporation of this product can greatly improve the workability of concrete, improve the physical properties of concrete, so that the compressive, tensile, flexural strength, elastic modulus and long-term strength of concrete are improved accordingly.
7. Suitable for high strength concrete, flowing concrete, early strength concrete, precast steam raised concrete, prestressed concrete, etc.
8. Especially suitable for use in the following concrete works: flow concrete, plasticized concrete, steam raised concrete, impermeable concrete, waterproof concrete, prefabricated components of natural curing concrete, reinforced and prestressed reinforced concrete, high strength ultra-high strength concrete.
9. This product can be used as the base material to make individualized admixtures with other components (such as early strength water reducing agent, retarder water reducing agent, pumping antifreeze agent and pumping water reducing agent, etc.), which can meet the requirements of different engineering categories, construction technology, construction technology and temperature conditions.
