High durability early strength RC slab surface repair material "Refremolset SP"
Achieves practical strength at an age of 1 to 1.5 days! It has high adhesion and prevents peeling.
"Refremolset SP (for deck slabs)" is a fast-setting polymer cement mortar for repairing the upper surface of RC deck slabs, made from high-performance special powdered resin and special fibers. The repair effectiveness has been verified through wheel load running tests in a water-saturated state, making it suitable for "bridges with less stringent time constraints" and "not requiring skilled techniques specific to ultra-rapid hardening materials," thus providing an easy-to-handle and highly durable cross-section repair material. Additionally, by offering three types of mix variations with mortar and concrete (special aggregate Gmax 5mm and crushed stone No. 6 Gmax 13mm), it accommodates a wide range of repair thicknesses and significantly contributes to reducing maintenance costs. 【Features】 ■ Three types of mixes available to match the repair target ■ Excellent strength development ■ Good adhesion properties with the deck slab ■ Excellent durability ■ Outstanding repair effectiveness ■ Suitable for large-scale construction *For more details, please refer to the PDF document or feel free to contact us.
basic information
【Other Features】 ■ Due to the early-strength polymer cement mortar, practical strength is achieved within 1 to 1.5 days of age. ■ By applying a high-durability epoxy resin adhesive to the bonding interface, it has high adhesion with the base concrete, preventing delamination. ■ Although it has high strength, the elastic modulus is kept at a level similar to ordinary concrete, providing excellent adaptability to temperature changes in the base material. ■ In evaluations of repair effectiveness through wheel load running tests, it has been verified to have approximately twice the performance compared to conventional repair materials (such as non-shrink mortar), even in water-saturated conditions. ■ It is compatible with mixing by mobile vehicles, allowing for large-scale and high-speed placement. *For more details, please refer to the PDF document or feel free to contact us.
