Description:

Repair mortar is a polymer-modified mortar, made of cement, stones, filler, and various high molecular polymers. Therefore, it combines the cohesion of polymer materials and the durability of inorganic materials. It can ensure the early strength of the mortar and other essential properties needed to repair concrete. As a part of the concrete repair system, the repair mortar is suitable for large-area concrete repair, including honeycomb, pockmarked surfaces, damages to the protective layers, reinforcement leakages, and deterioration of concrete structures caused by wear, freeze-thaw damages, corrosion or fire, etc. Repair mortar has excellent waterproof and anti-corrosion capabilities and can also be used for repair and new construction.

Our MelaColl™ MP products and Mikrant™ ET3060 are highly effective additives in repair mortars. They can improve the repair mortar’s water retention capacity, which can avoid decreased strength and crack caused by excessive drying and lack of hydration. They can also thicken the repair mortar to enhance its bonding strength and fluidity, thereby ensuring the repair mortar’s stability and workability. The list below illustrates the general functional properties provided by our products:

  • Improved water retention: MelaColl™ and Mikrant™ substantially reduce the loss of water into absorbing substrates in formulations. The water retention ability of MelaColl also strongly enhances the adhesion strength of repair mortar. This is because the repair mortar have enough time for hydration and at the same time do not lose water.
  • Improved thickening ability: MelaColl™ and Mikrant™ are used very often as a thickener in building applications as it prevents segregation and improves the cohesion of the formulation components. The viscosity of MelaColl depends on the degree of polymerization, concentration, temperature, shear rate, concentration of dissolved salts and modification.
  • Improved workability: Better leveling and reduced stickiness of MelaColl™ and Mikrant™ can be applied easily to repair mortar, which easy to operate and construction, and can significantly improve the construction efficiency.
  • Reduced shrinkage and cracking: Excellent water retention of MelaColl™ and Mikrant™ can extend the open time, reduce the shrinkage and cracking formation of repair mortar.
  • High early strength: MelaColl™ and Mikrant™ combine the cohesion of polymer materials and the durability of inorganic materials. They can ensure the early strength of the mortar and other essential properties needed to repair concrete.
  • Increased adhesion: MelaColl™ and Mikrant™ have good thickening effect, It can enhance the consistency and bond strength of the repair mortar, Suitable addition rate of it makes it has better adhesion feature.
  • Increased hydrophobicity (water repellent properties): After add MelaColl™ and Mikrant™, the hydrophobicity of repair mortar have improved, waterproofing effect is significantly increased.
  • Optimized flexural and compressive strength: MelaColl™ and Mikrant™ can significantly enhance the ability of flexural and compressive strength of the repair mortar.
