803 Construction Grout – SR
803 Construction Grout – SR is a pre-blended Portland cement grout containing non-ferrous admixtures to counteract plastic and drying shrinkage. Complies fully with ASTM C-827 test specifications for non-shrink Grout. 803 Construction Grout – SR is formulated using admixtures recommended for non-shrink grout by U.S. Corps of Engineers and American Concrete Institute publications. There are no corrosive or unstable ingredients in 803 Construction Grout – SR.
803 Construction Grout – SR is ideal for every phase of structural grouting which includes structural members, bridge seats, machinery bases, crane rails, anchorage systems, underpinning and concrete repairs. Ideal for use where a sulfate resistant grout is required.
Structural advantages: The purpose of non-shrink grout is to harden in full and total contact with all confining surfaces, and to remain permanently stable. 803 Construction Grout – SR ensures total void filling for all various grout consistencies, including the very flowable consistency. The hardened material will remain stable in all atmospheres and conditions that are generally conducive to the stability of good quality air-entrained concrete.
Advantages of field use: 803 Construction Grout – SR is very versatile in use and may be pumped, packed, or poured. Ambient temperatures during placing may vary from 39°F (4°C) to over 86°F (30°C). At normal temperatures the working time or “pot life” is one full hour, which allows ample time for mixing, transporting, and placing. Slightly accelerated or retarded working time will apply when working in hot or cool conditions respectively. Moderate vibration and agitation of the fresh grout is permitted. Other than conventional concrete curing requirements, no other special measures are necessary to preserve the stability of 803 Construction Grout – SR.
Complies with the following specifications: ASTM C-827, CRD-C 619 and CRD-C 621.

Internal Pressure Development When Confined
As insurance for maximum bearing contact the fresh 803 Construction Grout – SR mortar will exert a slight pressure against vertical confining surfaces as described by ACI and Corps of Engineers recommendations for foundation grout. Sonic testing for this group type (ACI Journal 78-41) indicates superior coverage and bearing contact when compared to all other grout types.
Volume Change on Cure
Within limits specified ASTM C–827 and CRD-C 621.
Curing of 803 Construction Grout – SR is important, especially in dry or drafty areas. Cure accordance with CSA A-23 for curing of concrete. If a curing compound is required, apply a curing compound after grout has taken initial set.
