3. Product Description
BASIC USE
MRT® has scientifically formulated and currently manufactures ArmorFast TM Rapid Hardening Hydraulic Mor-tar/Patching Material for concrete structures or concrete repairs. It is to be extended up to 100% with No. 57 or No. 7 stone and used in producing rapid setting concrete mix for use in repairs and overlays to concrete struc-tures or surfaces which need to be put back into service quickly. ArmorFastTM may be extended with gravel meeting AASHTO T 27, T 103, and T 84 or ASTM C 33 requirements.
COMPOSITION & MATERIALS
ArmorFastTM Rapid Hardening Hydraulic Mortar is a patented blend of ingredients including high quality, specially selected minerals of silica, alumina, calcium, special clays and other proprietary compounds. The cement portion is principally derived from recycled and activated coal fly ash. These ingredients are accurately measured, combined and blended at MRT’s manufacturing facilities using rigid quality control conditions.
PACKAGE SIZES
22.7 Kg (50 Lb) pails.
YIELD
One 22.7 Kg (50 lb) ArmorFastTM container will yield approximately 0.33 cu ft (9,345 cu cm) of rapid hardening mortar. When extended 100% will yield approximately 2/3 cu ft (18,689 cu. cm.) when properly mixed with water, as prescribed in the instructions below.
