sodium lignosulfonate superplasticizer are surfactants. After they are added to concrete, the hydrophobic groups are directionally adsorbed on the surface of cement particles, so that the cement has a negative charge. The cement particles with the same charge are mutually repulsed and dispersed under the action of charge repulsion. The flocculent structure formed by the cement at the initial stage of adding water becomes a dispersed structure, and the free water in the flocculent condensate is released, so as to achieve the purpose of water reducing agent. Therefore, adding wood calcium superplasticizer into concrete can reduce the water consumption of concrete mixture, reduce water cement ratio, improve workability, facilitate pumping and improve the strength, compactness and durability of concrete
High water-reducing rate: High water reduction efficiency at low dosage, giving the material system excellent flow. It can effectively improve the compactness and strength of the system, and the highest water reduction rate can reach 40%. High dispersibility: It has excellent dispersing ability, can absorb quickly and reduce mixing time.What's more,it endows the material system excellent workability and workability,therefore improves construction efficiency.It meets different construction requirements. High adaptability: It has good adaptability to various cement-based systems like ordinary Portland cement,sulfoaluminate cement system and Portland cement-sulfoaluminate cement composite system, and can be used with other additives such as: Defoamer, retarder, redispersible latex powder, cellulose, etc. Early strength and high strength:By adding PC-1008, concrete performs excellent early strength and enhancement effects. Under the same conditions, the early strength and enhancement effects of this product are higher than other types of superplasticizers, and the dosage can be relatively reduced. High durability:PC-1008 enhances the compactness of the hardened slurry, improves the impermeability, erosion resistance and chloride ion penetration resistance, improves shrinkage and creep properties, and reduces cracks. Green and safe: It does not contain harmful substances and is an environment-friendly material.
Introduction Product Name:Ferrous Sulphate Heptahydrate CAS No:7720-78-7 Formula:FeSO4·7H2O Formula Weight:278.05 Assay:98% Fe:19.8% Insoluble matter: 0.5% Application 98% FeSO4 7H2O Ferrous Sulphate Heptahydrate on cement and concrete has a retarding effect,less alone play a role and most of the other retarding agent, and most of the other retarding agent compound for additives or synergistic agent. Ferrous Sulphate FeSO4 ·7H2O which contains divalent iron (Fe2+) acting as efficient element for reducing harmful hexavalent chromium (Cr6+) to trivalent one (Cr3+) is the most used raw material for decreasing hexavalent chromium in praxis. Adding 98% FeSO4 ·7H2O Ferrous Sulphate Heptahydrate into cement will not affect the product property such as bending strength, compressive strength and water solubility etc.
1Polycarboxylate superplasticizer is a high range water reducing admixture. We are one of the best polycarboxylate superplasticizer manufacturers in China. Polycarboxylate based superplasticzer  is a free flowing, spray dried powder of  polycarboxylate resin. It's environment-friendly and widely applied to high performance concrete. It's dispersiveness is good, water reducing rate is high and adaptability to various cement. Fluidity of ixtures is excellent when used in concrete and mortar. It's also an excellent dispersion plasticizer suitable for gypsum, ceramic and other mineral materials.
Mainly required in the concrete that has high demands for high water reducing rate, slumploss resistant property, like commercial concrete, mass concrete, self-leveling concrete, etc. Also widely used in national project in fields including water, nuclear, and so on.
As a synthetic polycarboxylic acid high slump retaining water reducer, it has strong ability to maintain the dispersion of cement particl s The product has good adaptability to cement and high retention rate of double bond, which greatly improves the reaction activity of the product, so as to improve the utilization rate of the product and finally reduce the production cost of water reducing agent. 1.1% F-108(22%)is added in concrete,water reducing rate is above 30%. Improving early strength&strength after 28days Compressive strength 1day 180 3days 170 7days 160 28days 150. Greatly reducing W/B ratio,shrinkage and creep,improving durability. Low slump loss,slump retention index â?¥ 190mm. Complying with ISO14001:2004 certi ation,content of chloride ion 0.1%.
The product is mainly used to produce polycarboxylic acid superplasticizer products The polycarboxylic acid superplasticizer synthesized with it has higher water reduction rate, higher slump retention, good early strength, low alkali, low foam and low energy consumption. The third monomer is introduced: it has better molecular weight regulation function. The synthesized superplasticizer has uniform molecular weight distribution, good workability and low viscosity. The higher unsaturation ensures the higher eective content of the super chemical agent synthesized in the later stage, which is the most favorable guarantee for high water reduction rate and high slump retention.
