Product Name: Mother Liquid of Polycarboxylic Acid Water Reducer HSTPC
Product Overview: This product is the mother liquid of slump-preserving polycarboxylic acid high-performance water-reducing agent. Through the optimized design of molecular structure, it has excellent slump retention and high water reduction rate, which can greatly improve the plasticity of fresh concrete. Index, improve pumping and construction performance, at the same time, it also has a significant effect on the growth of concrete strength and structural development.
Main technical performance:
1. High fluidity and high slump retention, with little or no slump loss over time.
2. It has obvious enhancement effect on hardened concrete, 3d strength can be increased by 40~100%, 7d and 28d strength can be increased by 20~50%, and the later strength can still increase.
3. Excellent workability, no segregation, no bleeding, good pumpability, which is extremely beneficial to concrete strength growth and structural development.
4. It is suitable for a variety of cements and admixtures, especially suitable for high-performance concrete prepared by adding fly ash, mineral powder and other active admixtures.
5. No chlorine, low alkali, no corrosion to steel bars.
6. This product is non-toxic, harmless and environmentally friendly.
Scope of application:
1. It is suitable for concrete with high requirements for slump retention, such as large-volume, long-distance transportation and pumping concrete.
2. It is suitable for all kinds of key projects that require high concrete performance, such as water conservancy, marine engineering, ports, transportation, and electric power.
3. Especially recommended for high-strength, high-performance, high-durability concrete and super-fluid self-compacting concrete.
Usage and precautions:
1. This product is a colorless to yellow-brown viscous liquid, and the color and viscosity change slightly with the change of concentration.
2. This product can be used alone or in combination with other functional admixtures, and can be formulated into a series of admixtures with retardation, early strength, antifreeze and other functions.
3. The usual dosage of this product is 0.6~1.2% (based on the total amount of cementitious materials). The specific dosage varies depending on the actual situation. It is recommended to use the relevant adaptability experiment for the first time.
4. This product cannot be used in combination with naphthalene-based water-reducing agents. When it is compounded with other types of admixtures, relevant adaptability experiments should be carried out.
5. After pouring the concrete, please maintain the concrete in accordance with the relevant regulations of the construction regulations.
6. The effect of polycarboxylic acid water reducing agent is more sensitive to changes in aggregate mud content and admixture quality. It is recommended to select aggregates and admixtures that meet the standards.
7. It should be accurately measured during use to avoid large dosage errors.
Packing, storage and transportation:
1. 200Kg, 1000Kg drums are sealed, other specifications are customized according to user requirements.
2. Anti-leakage, anti-exposure and anti-high temperature during storage.
3. In the original packaging, the shelf life is 12 months. If the shelf life is exceeded, please conduct related tests before confirming the use.
