Anti-Bending Additives for Concrete for Railway/Road/Bridge Floors

Product DescriptionBending agent for concreteRA-KPerformance and use:RA-K bending agent is a new type of concrete admixture developed by our company for concrete with bending and tensile (bending) strength requirements. It is mainly used in concrete structures or components, such as pavement concrete, bridge concrete and precast railway sleeper. Its main characteristics are that it can significantly improve the bending strength of concrete, improve brittleness, save cement, reduce maintenance costs, reduce costs, open traffic in advance, and extend the service life of cement concrete pavement.Scope of application:This product is mainly used in road concrete, bridge concrete and precast railway sleeper requiring flexural tensile (flexural) strength.Main performance:1, in the case of constant slump of concrete, using the recommended amount of this product, the water reduction rate can reach 10 ~ 25%.2, this product uses reactive polymer copolymer as slump retention component, its slump retention ability is strong, workability is good, is conducive to centralized mixing, long distance transportation.3. This product can improve the flexural tensile strength (flexural strength) of cement concrete pavement. Under normal circumstances, the flexural tensile strength (flexural strength) of 28d cement concrete pavement can be increased by 15 ~ 20%.4, this product can significantly improve the early strength bending strength of concrete. 7d flexural strength increased by more than 20%, 28d flexural strength increased by more than 15%, 7d compressive strength increased by more than 25%, 28d compressive strength increased by more than 20%.5. This product can increase the folding ratio of concrete by more than 20%, improve the brittleness of concrete, reduce the generation of broken plates and cracks, and extend the service life of pavement.6. When the product is mixed with the benchmark concrete to maintain the same slump and strength, the cement can be saved by 10-25%.7, this product is non-toxic, odorless, non-burning, no corrosion of steel bars.Usage and precautions:1. Common dosage: The dosage range is 1.0% ~ 4.0% of the amount of cementing material. Use in strict accordance with the recommended dosage.2. Mixing method: When used, it should be directly added to the mixer with cement to extend the mixing time by 30 to 60 seconds.3, in order to ensure the best use results, it is recommended that users use this product, according to the type of cement, label and specific conditions of the project before the use of this product to carry out the necessary concrete test.   Packaging & ShippingPacking specification:1.
