ASTM C942 − 10 Standard Test Method for Compressive Strength of Grouts for Preplaced-Aggregate Concrete in the Laboratory

ASTM C942 − 10 Standard Test Method for Compressive Strength of Grouts for Preplaced-Aggregate Concrete in the Laboratory

Scope
1.1 This test method covers the determination of the compressive strength of hydraulic cement grout for preplaced aggregate (PA) concrete.

1.2 The values stated in SI units are to be regarded as standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

Summary of Test Method
4.1 Compressive strength of hardened grout is determined using top-restrained cubes as defined in Test Method C109/ C109M.

5.1 This test method affords a means for determining the compressive strength of grouts that expand and, in use, harden under conditions of partial to total restraint.

5.2 It is particularly applicable for determining the effect on compressive strength of grout fluidifier to be used with grout for PA concrete (See Specification C937).
