Dry powder mortar special Polycarboxylate SC-11 Product Overview Purpose: SC-11 is designed for dry mix mortar products polycarboxylate superplasticizer. The products and cement and other additives has better adaptability, is widely used in non-shrink cement grout / mechanical grout, repair mortar, cement mortar base floor, waterproof mortar, grouts and Polystyrene insulation mortar cement based powder materials, to improve the mobility of the mortar, mortar late strength increase early and reduce shrinkage cracking mortar cured late great help. In addition, this product can also be applied to gypsum-based dry powder material, refractory and ceramic products. Features: 1, high water reduction: reduction of water to make mortar rate of more than 20%, in the case of the same amount of water in the mortar, mortar greatly improved mobility; 2, early strength and high strength: the ability to improve the early strength of mortar improve the ultimate strength of a variety of applications that require fast cure is the best option; 3, high durability: reduced water-cement ratio of mortar, improve durability, reduce shrinkage and creep deformation, reducing post-curing shrinkage cracking mortar; 4, green products: the production process does not produce pollution of the natural environment. Technical Specifications: Item Index Item Index Appearance white powder moisture content (wt%) ≤3 bulk density (g / l 500-550 loss on ignition (wt%) ≥85 PH value (20% solution) 7.0-8.0 chloride ion content ( wt%) ≤0.1 cement paste fluidity (mm) ≥240 mortar water reduction (%) ≥20 Recommended dosage: in a variety of dry materials recommended dosage is 0.2 to 0.3% of cementitious materials packaging: 1, the product is 25 kg paper bags; 2, according to customer requirements, providing a large bag or special packaging Storage: at room temperature (below 40 ℃) and stored in a dry environment, avoid stacking or stress, avoid products. agglomeration occurs Shelf life: This product storage stability in their original packaging can be kept for 12 months after opening the original packaging should be put to use in 60 days Polycarboxylate commonly used in dry mix mortar superplasticizer performance. Contrast type water rates to maintain the fluidity of the strength of the high operational cost Polycarboxylate fairly high level of naphthalene superplasticizer the difference in height in the high school wood melamine water reducer superplasticizer low in calcium Good in low self-leveling cement mortar cement mortar is recognized as the highest-tech products in the product because of the self-leveling cement formulations designed to solve three major conflicts: 1, retarding the early strength of contradiction; 2, high fluidity. contradiction with the anti-settlement; 3, the contradiction between contraction and expansion in the use of self-leveling mortar Polycarboxylate to resolve these contradictions have greater advantages: 1, Polycarboxylate with high slump resistance and of its slump is mainly achieved by steric hindrance, thus achieving high slump resistance and ultra strength of unity. In the traditional self-leveling formulations usually add some retarder to ensure the flow of operating time and 20 minutes degrees, and retarders due to changes in the cement hydration process can sometimes produce cement will adversely affect performance while using Polycarboxylate can basically do not use retarder, less early strength agent, thus simplifying the recipe, reduce costs and improve the quality of stability. 2, Polycarboxylate has a slight lead due to gas and water reducer and other different adsorption mechanism, making self-leveling cement mortar under high flow can achieve a very low degree of bleeding water rate, which is not available in other superplasticizer; this is Polycarboxylate especially for self-compacting concrete three main reasons, the most vulnerable aspect of mortar leveling problem is coming through expanders. process shrinkage compensating cement expansion effect expansive great relationship with the curing conditions, if improper maintenance, it is prone to cracking, chalking and other performance deficiencies, but we all know, is often self-leveling cement-free conservation using polycarboxylate shrinkage reducing agent system will greatly reduce, so that in most cases the system is in the state of micro-expansion, thus greatly reducing the incidence of engineering accidents, but also makes a better adaptability, self-leveling products. Fully above, we have reason to believe Polycarboxylate cement leveling mortar optimum superplasticizer.
