For that reason alone, I don't like C It actually does neither, so to me, the results are somewhat meaningless. But nevertheless, it is accepted and promoted by the industry.
RE: Masonry Grout Testing? The concept of putting 11" slump gout into a non-absorbent mold will yield meaningless results regarding the performance of the structure and the results should be rejected.
All of the current code standards are based on the grout testing method that have be used as documentation of the grout for decades of testing and research because it provides the most realistic measure of properties. Keep in mind that gout is one component in a structural element the wall and is not like a test of delivered concrete in cylinders made from placed concrete that is the main building component.
In masonry, the grout strength is not that important, since its purpose is to transfer the loads from the wall into the reinforcement usually and the grout strength should be approximately the strength of the net unit strength.
Grout should not be used to increase the vertical strength of a wall, but is intended to transfers loads between the masonry units and the reinforcement if needed. Excessive grout strengths in prisms could result in the fibers with the highest stress to be lower than the average prism strength.

Testing Prisms Two days prior to the 28 day time interval or the designated Prism Net Cross-Sectional Area testing time, each prism is removed from the moisture tight To provide accurate an accurate strength calculation, bag.
Prism age is determined from the time of laying units for the laboratory needs to determine the net area of the prisms.

No other capping materials strength of a prism depends on whether the prisms are grouted are permitted, nor are unbonded caps. For ungrouted full-size prisms, the cross-sectional Capping provides level and uniform bearing surfaces for testing, thereby eliminating point loads due to surface irregu- larities.
The result is more uniform and reliable compressive strength values. Patching of caps is not permitted because it is dificult to maintain a planar surface within the tolerances of ASTM C Capping materials must have a compressive strength of at least 3, psi Caps are to be aged for at least 2 hours before test- ing the specimens, regardless of the type of capping material. Capping plates of adequate stiffness and smoothness are critical to achieving accurate results.
Machined steel plates of 1 in. Once determined, the centroidal axis can be marked on the end of the prism.
To test the prism, it is placed in the compression machine with both centroidal axes of the specimen aligned with the ma- chine's center of thrust. The maximum load and type of fracture is recorded. Prism strength is calculated from the maximum load divided by the prism net area.
This prism strength is then corrected as described below. The capping wear compressive strength of the prism by the correction factor plate must be plane within 0.
