Admixtures

PCE is a polycarboxylate based high range water-reducing admixture which enables concrete to be produced with very low water to cement ratios. Polycarboxylate superplasticizer is compatible with air-entraining agents, microsilica, accelerators and many other admixtures; however,each material should be added to the concrete separately.

Method and cautions Dosage (total cementitious materials): Powder 2.0~3.0%, Liquid 2.0~3.0% Powder admixture can be added with binding materials, liquid with mixing water. Increase mixing time properly. Hot water helps to improve its performance. In winter constructions, no ice, snow or freezing elements in aggregate materials. Raw materials should be pre-heated if possible. After pouring, cover plastic film and enhance thermal insulation curing. The optimum mix design needs to be determined by the requirements of the project, specialties of materials and mixture tests before usage. The feasibility of combination with other admixtures needs to be conformed by mixture tests. This powder product is packed into plastic knitting bags, 50 kg/bag; the liquid product is packed into plastic barrel, 200~250kg/BBL or transported by tankers. During storage, it needs to be prevented from moist, broken packed and high temperature. The effective duration is one year. Expired product needs to be determined by tests. This product is not inflammable or explosive and need to be well kept.

Corrostop-15 which is a 3 in 1 Corrosion inhibiting concrete admixture tested & approved by IIT, Madras ,iNDIA with the below advantages. Advantages: 1)Works as Anti Corrosion for the TMT rods in Concrete & hence increases the building life 2)When Corrostop-15 is used, it reduces the water: cement ratio & completely seals the invisible pores in the concrete & hence acts as an excellent water proofing agent. Hence do not require separate water proofing chemical. 3)CORROSTOP-15 arrests the airline cracks in RCC roofing 4) Corrostop-15 can also be used as Wall plastering admixture with M-Sand which leaves the walls stronger with no air cracks. 5) Compatible with all grades of concrete.

We design and make various industry defoamers, have good defoamers for concrete admixtures, water reducer.

Our Brand Volsil - Silica Cement Admixture contain more then 92 % of amorphase silicon dioxide and high surphase area... Volsil A-Sio2 is a pozzolanic material containing A-Sio2 amorphous silica and minor amounts of residual minerals Test results indicated that the concrete specimens containing 5%, 10 %, 15 %, 20% A-Sio2 replacement by weight for cement had the best compressive and flexural strength and the replacement of cement separately and together using a super plasticizing admixture could be utilized to improve the mechanical properties of the conventional concrete mixtures. Amorphous silica (a-SiO2) in fine-grained form possesses a high pozzolanic activity which makes it a valuable component of blended binders in concrete production. The origin of A-SiO2 applied in cement-based composites is very diverse. SiO2 in amorphous form is present in various amounts in quite a few supplementary cementing materials (SCMs) being used as partial replacement of Portland cement. In this work, the applicability of a commercially produced silica powder as a partial replacement of Portland cement in cement paste mix design is investigated. Portland cement CEM I 42.5R produced according to the EU standard is used as a reference binder. silica is applied in dosages of 5 and 10, 15, 20 % by mass of cement. The water/binder ratio is kept constant in all the studied pastes. For the applied silica, specific surface area, density, loss on ignition, pozzolanic activity, chemical composition, and SiO2 amorphous phase content. For the developed pastes on the basis of cement-silica blended binder, basic physical properties as bulk density, matrix density, and total open porosity are accessed. Pore size distribution is determined using MIP analysis. Initial and final setting times of fresh mixtures are measured by the automatic Vicat apparatus. Effect of silica cement admixture on mechanical resistivity using compressive strength, bending strength, and dynamic Young''''s modulus measurement. The obtained data gives evidence of the workability of paste mixtures with silica, whereas the setting process is accelerated. On the other hand, the reaction activity of silica with Portland cement minerals results in a slight decrease of porosity and improvement of mechanical resistivity of cement pastes containing a-SiO2.
