Oct 03, 2019 This cylinder is subjected to compressive stress. Depending on the type of parent rock gives the different crushing value of aggregate as a compressive strength varying from a minimum of about 45 MPa to a maximum of 545 MPa.. It is a fact that parent rock compressive strength does not exactly indicate the strength of aggregate in concrete.
