JH-GHL polycarboxylic acid superplasticizer (liquid)

1. Product introduction
JH-GHL polycarboxylic acid high-efficiency water-reducing agent is a new generation of high-performance water-reducing agent produced by our company. It has original technology and excellent comprehensive performance. It is a product of various strength levels. Ideal admixture for concrete and precast concrete components.
2. Product Features
1. Good water-reducing rate: This product has good water-reducing performance at low dosage, and the effect is particularly significant in high-grade concrete (above C50). The rate can reach 40%;
2. Excellent plastic retention performance: Because the steric hindrance of the extended polymer side chains effectively hinders the secondary agglomeration between cement particles, the product has high dispersion properties and This performance can be maintained for a long time, achieving excellent plastic retention ability of the concrete mixture.
3. Good early strength and reinforcement effect: Under the same conditions, the early strength and reinforcement effect of concrete added with this product are higher than other types of high-efficiency water-reducing admixtures.
4. Significantly improve the durability of concrete: The product's low alkali content, and because the water-reducing agent is an air-entraining water-reducing agent, can significantly reduce the alkali-aggregate reaction of concrete and improve the frost resistance of concrete. financial ability.
5. Dimensional stability: The concrete mixed with this product effectively improves its shrinkage and creep properties, has good high dimensional stability and reduces the risk of cracks.
6. Excellent water retention performance: The concrete mixed with this product has significantly less bleeding and no segregation than the basic product; it is easier to implement construction operations.
3. Recommended dosage and usage
1. The general dosage of JH-GHL polycarboxylate superplasticizer is 0.3-1.5% of the total weight of the cementitious material. When preparing high-strength concrete, The dosage can be up to 2.0%; the specific dosage should be determined through experiments.
2. This product can be added to sand, stone, cement and admixtures together with mixing water for the specified time.
4. Scope of application:
JH-GHL polycarboxylic acid high-efficiency water-reducing agent can be used to produce commercial concrete and concrete precast components of various strength levels. It is suitable for preparing ordinary strength concrete, high-strength concrete, and self-compacting concrete. Concrete, fair-faced concrete, high durability concrete, etc. It can be widely used in industrial and civil construction, municipal engineering, water conservancy and hydropower projects, roads and bridges, subways and other fields.
V. Precautions
1. Do not mix it with naphthalene series superplasticizer at the same time.
2. Experiments must be carried out when mixed with other admixtures.
6. Packaging and Storage
This product is a liquid product, 200kg/barrel, 50kg/barrel. It should be stored in a cool and dry place, away from direct sunlight. Shelf life is 12 months. </p
