polycarboxylate acids superplasticizer of company is a new polycarboxylate series of high reducing-water for the environmental protection. Homogeneity of the water reducing admixture and the performance mixed concrete has reached the similar level of foreign products; it is advanced in the domestic. It has the retardation, early strength, high efficiency reducing water, which can be widely used in ordinary concrete, pumping concrete, super-fluid state of self-compacting and high-performance concrete, it has the excellent performance especially in the application of high-strength high performance concrete. The molecul’s main chain of polycarboxylate acids superplasticizer adsorbed on the surface of cement particles, the branch chain is surrounded around by cement particles, which played the role of steric hindrance. This is the difference from the traditional water-reducing admixture who dispersed cement particles by electrostatic repulsion mechanism. It has better dispersion ability, plasticity-maintaining and reducing -water effect, the concrete has a comprehensive qualitative leap in performance. 1. The suitable dosage range is 0.5% -1.4%, for high-strength and ultra high-performance concrete can be configured to appropriately increase dosage, but the maximum dosage should not exceed 2.5%. For specific cement it should be determined through experiments. 2. High reducing-water rate is 40%, which is in order to enhance the strength of concrete, to save the cement, it provides a guarantee, it can be used for the preparation of more C80 and C80 high-strength high performance concrete, the reducing-water is different under their different dosage rates, higher dosage higher water-reducing rate. 3. Excellent dispersion and self-compacting nature can prepare different strength class super fluid self-compacting concrete. 4. Can be a substantial increase in early and late strength, it increase the project construction schedule. 5. Good plasticity-maintaining could significantly prolong the transit time of concrete and settling in site of the residence time, it reduce economic losses and ensure the normal pumping of concrete. 6.It has a wide range of adaptation to various silicate cement, ordinary silicate cement, slag silicate cement and all kinds of mineral admixtures, and it has better dispersion and plasticity-maintaining. 7. The low-dosage, 0.5% -1.4% of the low dosage and naphthalene superplasticizer compared to other high reducing-water, which has an economic advantage.

high range set retarding water-reducing admixture, which is combined of the naphthalene series and the amount of high-performance water-reducing retarder, stabilizer, reinforcing admixture, has a high efficiency water-reducing, retarding in the initial setting and early strength in final setting, late-enhanced, small slump loss etc. it is the perfect concrete admixtures for the preparation of high-performance, high-strength concrete, mass concrete and long-distance transport of concrete. The product can be produced powder and liquid, to meet different engineering requirements. 1. Dosage range: Powder dosage amounts to 0.5-1.2% of total cementitious material, the liquid dosage amounts to 1.5-3% of total cementitious material, reducing-water rate is 15-25%. 2. A slight increase in air content is beneficial and without adverse effects on the concrete. 3. The product has the retarding plasticity, small slump loss, which is extremely beneficial to the transport and to pouring of concrete. 4. The product has a retardation 1-3h, it can also be adjusted for setting time basing on the user's demand. It has not affected the strength growth of concrete. 5. The compressive strength of concrete, flexural, tensile, impermeability and durability are significantly improved and enhanced. 6. the product has the broader applicability of cement, which is the preferred preparation of concrete.

Early strength water-reducing admixture is a chlorine-free concrete admixtures which is composed of early strength and water-reducing and other components, with excellent early strength performance and water-reducing performance, it can increase the early strength and the later strength at low temperature environmental condition, increase significantly the pumpability, improve the workability, it have been widely used in various projects as the main measure to speed up the progress and improve the efficacy. 1. Dosage amounts to 01.5-2.5% of cementitious material, it can reduce the unit water consumption by 10-15%. 2. Incorporation of the product in keeping the same slump, it can save 10-15% of cement, the strength is not reduced. 3. Suitable for steam curing, the intensity increased rapidly, and with the same slump and the same water consumption, the concrete strength increases 50-120% for 1 day, increased 40-100% 3 days, and increased 30-80% 7 days. 4. There is still a corresponding increase in later strength of concrete while mixing with this product. 5. Suitable for works -5 ℃ -30 ℃, it can accelerate the progress of the templet and of the construction, it has a economic and technical effects. 6. The product has neither retarder nor air-entraining, which has a wide range of adaptability, it can improve the main mechanical property of concrete and improve the impermeability performance of concrete, but no effect on concrete shrinkage.

it is non-chlorine compound antifreeze admixture which compounds by water-reducing, early-strength, reducing the freezing point, preventing freezing damage etc. ingredients, powder, it has early-strength, water-reducing, air-entraining, anticorrosion etc. functions. It is mixed to the concrete according to the request, can obviously improve the configuration of the capillary pores and reduce free-water and the freezing point of the concrete effectively. And it can accelerate cement hydration and concrete hardening under the low temperature condition, enhance the early strength greatly and make the strong more and more by time, is ideal admixture for construction in winter. 1. The mixing amount was equal to 3.0-4.5% of cementing material, water-reducing rate 15-25%. 2. This product is non-chlorine, non-ammonia and low-alkali compound antifreeze, have anti-freezing and water-reducing double functions, and can’t cause reinforcingsteel corrosion. Through adjusting mixing amount, it can meet the requirements for 0℃— -20℃ construction in winter. 3. This product uses new anti-freezing materials, which greatly reduce the alkali content and avoid the alkali - aggregate reaction. 4. The concrete workability can be improved greatly by using it, also the Physical Properties of concrete can be increased and improved, and enhanced freeze-thaw cycle resistance of the concrete. It is applicable for preparing the anti-freezing pumping concrete. 5. It is applicable to all kind of the below C50 reinforced concrete and prefabricated components. Compounding the above C50 concrete can use with superplasticizer or requesting our company to adjust.
