Nettet27. feb. 2024 · R-value Units As we said before, the R-value measures the thermal resistance of a material. This can also be expressed as the temperature difference that will cause one unit of heat to pass through one unit of area over a period of time. R-value Equation (Imperial units) R-value Equation (SI units) Nettet26. aug. 2007 · 1) ASTM C 90 units 2) Maximum bed joints of 5/8 inch 3) ASTM C476 grout. 4) Minimum grout strength = 2000 psi. So if you specify a C-90 block, 2000 psi grout, and the type of mortar to be used, the PRISM strength does not have to be specifed, and the compressive strength can be obtained from Table 2 of the masonry code.
