CMU properies

CMU properies

CMU properies

(OP)
Hello,

I am making a RAM model that I need to model in a CMU wall for. I read online it is more accurate to use the "other" option instead of a concrete wall. When going into the other option it asks for the properties of CMU. One of the properties is the modulus of elasticity.

The equation for E for CMU = 900 (f'm).

I can't seem to find a good answer for what a typical value of f'm would be.

Does anyone have any suggestions?

Thank you

RE: CMU properies

CMU strength is usually between 1500 psi to 2000 psi. Considerably higher strengths can be obtained at a premium, but, for 'run of the mill' type construction the compressive strength will be slightly above 1500 psi.

Dik,

I understand, what is f'm typically with the combination of the grout and the block?

RE: CMU properies

No, not grout - f'm is the compressive strength of the combination of the mortar and block in an assembled condition.
