GROUT MIX SPECIFICATIONS MEGAPOXY: High strength resin base for epoxy concrete, structurally compatible with Portland cement, concrete and asphalt concrete. Suitable for deck expansion joint nosings and all structural components in which Portland cement concrete or asphalt concrete and epoxy concrete are in combination. Mixing proportions : Equal parts “A” and “B” by weight or volume. Work time : 15 Minutes Set time : 1 Hour Film touch dry time at 25°C : 1½ Hours Specific gravity : 1.1 Colour when mixed : Black Compressive strength : 28 Mpa Tensile strength : 6 MPa Elongation at break at 25°C : 40% Impact strength at 25°C : 22,5 kg cm/cm² SURFACE PREPARATION Asphaltic concrete : Scrub with water containing detergent, hose and allow to dry. NOTE : Megapoxy CT will stick to damp surfaces, but it is advisable to completely dry the surface whenever possible. RAPID SET, HIGH TENSILE CONCRETE: Megapoxy CT mixed with dry, clean sand and aggregate provides high compressive and tensile strength concrete, suitable for deck expansion joint nosings and other applications where impacts and tensile stresses cause early break up of asphalt and Portland cement based concretes. MEGAPOXY CT MORTAR: • 1 Part by volume mixed Megapoxy CT • 2½ Parts volume epoxy quality sand. “PLASTIC” HIGH SLUMP MEGAPOXY CT CONCRETE: • 1 Part by volume mixed Megapoxy CT. • 2½ Parts by volume epoxy quality sand. • 4 Parts by volume 5mm diameter dry crushed stone.
