ProductsOverview:
LC-PC-ZQPolycarboxylic acid series high-performance water reducing agent (early strength type) is a new type of water reducing agent newly developed by our company with carboxylic acid graft polymer as the main body. Due to its unique molecular structure, the water reducing agent can realize the dispersion of cement particles through the dual action of electrostatic repulsion and spatial barrier, showing excellent dispersion and strong integration to improve the hydration products of cement, making it denser and higher early strength. It has the characteristics of low dosage, high water reduction rate, good early enhancement effect, low alkali content, chloride ion content, sodium sulfate content, no corrosion of steel bars, environmental protection and no pollution. The product has good adaptability to the five major cements, especially suitable for high-flow, high-strength and ultra-high-strength concrete projects. This product is widely used in concrete construction of railway, highway, water conservancy and hydropower, industrial and civil construction projects, and it is also an ideal material for preparing high-performance concrete for railway passenger dedicated lines.

Technical performance:
The performance indicators of this product meet and exceed the JG/T223-2007 "polycarboxylate high-performance water reducing agent", GB8076-2008 "concrete admixture", TB/T3275-2011 "railway concrete" on the polycarboxylate high-performance water reducing agent of the first-class standard requirements.
This product has good water reduction and dispersion effect, especially in high-grade concrete (above C50).
The early strength of concrete is high, and the late strength is not damaged. It is suitable for precast components and concrete projects with high requirements for early strength.
This product has good early strength and strengthening effect, 1d compressive strength increased by 80~100%,3d compressive strength increased by 70~100%,28d compressive strength increased by 30 ~ 50%.
The organic polymer corrosion inhibitor in this product can eliminate SO42-、CL-A large number of closed gas micropores block the migration of corrosive ions in concrete, so that the corrosion resistance of concrete is greatly enhanced.
The concrete mixed with this product can effectively improve the shrinkage and creep performance of concrete, has good high dimensional stability, and reduces the risk of cracks.
This product has excellent water retention performance, improve the workability of concrete, mixed with this product after the concrete bleeding rate is significantly reduced. There is no segregation under large slump, and the pumping resistance is small, which is convenient for transportation. The concrete surface has no bleeding line, no large bubbles and small color difference, which is especially suitable for concrete with high appearance quality requirements.
Product adaptability, the product is adapted to a variety of specifications, models of cement, and slag, fly ash and other active admixture phase compatibility, good adaptability.
Product performance is stable, long-term storage without stratification, no precipitation, no crystallization precipitation in winter, non-toxic, non-irritating and radioactive, does not contain the steel by the corrosion of dangerous substances.
Method of use:
Recommended doping: 1.0-2.0 of the total amount of gelding material.
This product can be added into the mixer at the same time as the mixing water to control the measurement error within + 1% and extend the mixing time for 30s. The water in the solution shall be deducted from the mixing water.
This product should be stored separately, avoid mixed storage with other types of admixtures, it is strictly prohibited to mix naphthalene water reducing agent, liquid accelerator storage and use.
