HARDCRETE 310 is a cementitious pre-packed repair mortar specially designed for resurfacing, patching, and repairing large areas of concrete at a minimum thickness of 10mm. It is supplied as a single component powder, which only needs mixing with a specific quantity of water to produce a non-shrink and rapid strength-gain mortar. It is based on a blend of special cement, modifying additives to control the rate of setting and strength gain, and selected hardwearing aggregates.
