Profile: Zhe Jiang LanYa Concrete Admixture Inc. specializes in the research, manufacture and distribution of concrete admixtures. We produce poly-carboxylate superplasticizer, naphthalene based superplasticizer, melamine based plasticizer, expanding admixture, asphalt antistripping admixture, sodium lignosulphonate and cement grinding aids. These products are widely used in industrial & civil engineering, public infrastructures, hydraulic electricity engineering and concrete ready-mix products. Our LY-PC is a new generation super- plasticizer based on polycarboxylate technology. This product is designed to provide medium to high water reduction, while providing excellent flowability during placement, and excellent slump retention without affecting initial setting time. This product is designed to produce high-strength, flowable and self-consolidating concrete in a variety of applications. It meets the standard requirements of GB8076-1997 and GB50119-2003. Our LY07 asphalt antistripping admixture is an asphalt modified admixture of big molecule amine. In road construction, adding this agent in proportion, improves the surface energy, the polar and the adhesiveness. It also improves the capabilities of anti-aging, waterproofing and antistripping, so as to improve the grade of adhesion between asphalt & acid stone from 1-2 to 4-5. Sodium lignosulphonate water reducers are mainly used for concrete mixture as water-reducing additive. These are widely applied in building, dam and thruway projects. It can reduce 10% of water consumption and improves the mixture of the concrete. It can also reduce the initial stage of the cement heat of hydration by a large margin.
