01What is Repair mortar?

Repair mortar primarily consists of cement, mineral admixtures, aggregates, fillers, and additives. This cement-based mortar is used for repairing structures and buildings. Its key technical indicators include compressive strength, bond strength, interfacial flexural strength, abrasion resistance, and drying shrinkage. For specialized applications, additional properties such as corrosion resistance, permeability, chloride ion content, water absorption, and setting time must also be considered. flexural strength, bond strength, interfacial flexural strength, abrasion resistance, and dry shrinkage rate. For specialized applications, additional properties like erosion resistance, water resistance, chloride ion content, water absorption, and setting time must also be considered.

Reinforcement mortar primarily consists of cement, fine aggregate, admixtures, and additives. It is a high-strength cementitious mortar used for strengthening concrete structures.

03Additives

Additives significantly enhance mortar adhesion, prevent cracking, improve workability, control coagulation, and increase early strength. By combining polymers (such as polymer emulsions) with chemical admixtures (like water-reducing agents and early strength agents), repair mortars become more durable and easier to apply. This adaptability to diverse substrates and environmental conditions makes them essential for modern high-performance repair materials.
