WOXIN JS 3 испытательное устройство защиты уменьшение воды поликарбоксилат Суперпластификатор

Product Model: JS-3

The main of PCE-powderis a carboxylic acid grafted polymer and it is a water-soluble water-reducing agent liquor. The main characteristics are high water-reducing rate, high protection slump, high strength and low shrinkage. It can be used to prepare concrete in different strength grades, especially suitable for concrete preparation for high strength, high flow state, self-compacting, high durability, and high performance.

Technical Feature 
1. High water reduction rate, water reduction rate up to 38%-40% 
2. High flow state, high protection slump, and slump loss low. 
3. It has obvious strengthening effect on hardened concrete. It can be increased by 70% to 100% in 3 days, by 40% to 60% in 7 days and 28 days. 
4. Fresh mix concrete has good flow-ability, no segregation and no bleeding water. It also has a good pump-ability. After concrete hardened, its appearance is smooth, with solider inside. 
5. No chlorine, low alkali, no corrosion to steel reinforcement. It is a nonhazardous, safe for both health and environment product. 
6. The air content can be adjusted according to the needs of the project. 
7. The freezing resistance, seepage resistance, carbonation resistance and shrinkage resistance of concrete are remarkably improved. It can greatly extend the service life of concrete. 
8. The product has good applicability, Suitable for various types of cement. Especially suitable for High strength, high flow and high performance concrete prepared with active admixtures such as fly ash(Coal ash), fine ore powder(ground blast furnace slag), etc.

Application Range
1. This product is white alkaline solid. It is a non - toxic, non - corrosive, non - polluting product. 
2. Suitable for the preparation of various grades of pumping concrete and long distance transportation of commodity concrete. 
3. Suitable for high strength concrete, liquid concrete, self - compacting concrete, mass concrete, high performance concrete, clear concrete structure (Plain concrete structure). 
4. Suitable for all kinds of civil engineering, high-rise reinforced concrete frame shear structure. It is especially suitable for large concrete structures that require high durability of concrete such as expressways, railways, Bridges, tunnels, hydraulic DAMS, nuclear power plants, ports, wharves and underground facilities. It is also suitable for the production of large prestressed concrete beams and slabs, steam curing concrete, etc. 
5. Before use, the optimum dosage should be determined according to the construction requirements, material characteristics and trial distribution. 
6. Use should be accurate measurement, to avoid large dosage error, prevent repeat filling, leakage filling. 
7. It can not be compound used with naphthalene series water reduce. While compound use with other variety admixtures , should be confirmed by the test. 
8. After concrete is poured, concrete shall be maintained in accordance with the provisions of the construction regulations. Construction in winter should comply with the winter construction regulations. 
9.The change of the content of sand and stone and the quality of admixture have a great influence on the water reduction effect of the product. The client should select the aggregate and blending materials that meet the standards. The Changes in the content of sand, stone and the quality of admixtures may make a great change on product of water reduction effect.
