1. Rationale
Rational for adding ASTM C 1600 Standard Specification for Rapid Hardening Hydraulic Cement to ASTM C 887 Standard Specification for Packaged, Dry, Combined materials for Surface Bonding Mortar. The advantages of ASTM C 1600 Standard Specification for Rapid Hardening Hydraulic Cement are faster construction time, rapid return to service for repairs, lower shrinkage, better resistance to chemical attack, improved resistance to freezing and thawing than conventional materials. It has been utilized in formulated mixtures for many years. The approval of C 1600 allows legitimate formulation to include it in mixes for use. As well, solid walls for safety barriers may be constructed and placed in service faster and potentially offer higher resistance to impact from unsafe activity. C 1600 cements can offer faster return to service and higher strengths at similar cement contents when compared to normal setting and hardening cements. Currently the C 887 Standard Specification for Packaged, Dry, Combined materials for Surface Bonding Mortar presently does not include ASTM C 1600 Standard Specification for Rapid Hardening Hydraulic Cement although it does include other ASTM Cement Specifications cements. The addition of C 1600 to the other ASTM cement types will allow the designer more legitimate versatility.
