Detailed Description

sulfonated melamine series resins Description Concrete High-range Water-reducer SM (Sulfonated Melamine-formaldehyde Resin) is a polymer electrolyte, SM is the best one of existing concrete admixture in comprehensive properties. It is able to prepare high-strength concrete and flowing concrete by adding SM into Ordinary Portland Cement. For high-strength concrete the compressive strength will reach or surpass xxxxx concrete is largely used in high-raise building and many important prestressed concrete structure of civil engineering. The flowing concrete is usually used for in-site casting and pump concreting, such as mass foundation and other structure with closs arranging reinforcement . It has a excellent compatibility for Aluminous Cement. It metallurgical industry SM is often used as major admixture for refractory concrete, included castables and field mixes. Principle Technical properties xxxxx dosage within 0.5-1.0% by weight of cement, the water reduction rate will be 20-25% 2.When dosage is appropriate, it is able to increase the compressive strength of concrete and mortar by 40-100% at one day, by 30-60% at 28 days. The later age strength also in crease (about 20%). xxxxx is able to prepare high strength concrete (60-80Mpa, even higher) by using 45.5#-55.5# Ordinary Portland Cement. 4.Adding SM to refractory concrete, from Aluminous Cement, the strength after drying at 110 temperature degree and after burning at high temperature will increases obviously(by 60-170% for compressive). 5. Because of no air-entrainment SM can be used curing of concrete and their products. 6. The SM is usually applied for α-hemi hydrate gypsum and β-hemi hydrate gypsum, When dosage is 0.5-1.0% by weight of gypsum, It is able to increase the strength of gypsum by high water-reducing rate. Properteis Outward appearance: White powder or colorless Transparent liquid Water content (powder)(%): < 3 Solid substance (liquid) (%): 20+/-1 PH value (20degree C., 20% solution): 8-9 SO 4 ion content (%): 3-4 Cl ion content (%): 0.03-0.04 Surface tension (mN/m): 71.5-72.0 Suggested mixing amount:0. 3- 1.0% (of the cement amount) Suitable application range This product can be applied in the high strength concrete, the high fluidity concrete, the high duration concrete, the aluminate cement refractory concrete or the low cement refractory concrete, the grouting materials, the steam curing concrete, the high strength mortar, the gypsum products, The self-flowing ground, the stuffing materials, the grouting materials, and so on. It also can be used as the brightened agent for manufacturing the coloured ground brick and the tunnel liner. The liquid product can be used as the mother liquor to compound the other additional agent. Package Powder: plastic sealed bag. 20kg per bag, solution: in bulk 250kg drum. Storage This powder is easy to absorb the moisture from the air. So it must be kept in the original sealed bag and stored at the dry place. The storage period is one year. Transportation This product is non-toxin and non-flammable. So the transportation requirement is general.
