Capping materials must have a compressive strength of at least 3,500 psi (24.13 MPa) at an age of 2 hours when cubes of the material are tested in accordance with ASTM C617, Standard Practice for Capping Cylindrical Concrete Specimens (ref. 13). The average thickness of the cap must not exceed ⅛ in. (3.2 mm).

Determine compressive strength by dividing maximum load by net cross-sectional area For alternative methods of forming: Calculate average corrected compressive strength by dividing maximum load by cross-sectional area, and then multiplying the result by the conversion factor Conversion factor for alternative methods specific to
TSD215. TMS 602-13 CONCRETE MASONRY COMPRESSIVE STRENGTHSThere have been several significant c. nges in the 2013 masonry code and specifications. Table 2 values for f’m in previous editions of the masonry specifications were based on prism t. ts that did not use consistent bedding practices. Recent prism testing of concrete masonry units has ...

states, “Determine the compressive strength for each wythe by the unit strength method or by the prism method as specified here.” The MIM recommends using the unit strength method, and TMS 602 Article 1.4 B.2.b. states: Use Table 2 to determine the compressive strength of concrete masonry based on the strength
Jul 17, 2024 · Compressive strength of grouted concrete masonry is an important parameter to design reinforced/grouted concrete masonry walls. The design standards stipulate two methods to determine the compressive strength of masonry (1) using tabulated unit strength and mortar type, and (2) testing representative masonry prisms. The compressive strength prediction of grouted concrete masonry is influenced ...

Once f’m is determined, the last concrete material to define when specifying masonry is grout. Grout compressive strength, f'g must be defined. TMS code requires f'g to be equal to, or exceed f’m, but not less than 2000 psi. When f’m = 2500 psi, f'g must be 2500 psi or greater. Some in the industry suggest using grout strength comparable ...
