(crushed quartzite, crushed granite, limestone, and marble). While the high modulus of the crushed quartzite (110 GPa [16,000,000 psi]) did allow the production of concrete with an MOE approaching 50 GPa (7,250,000 psi), this also required the use of a very low w/cm of 0.26. Again, such a mixture can be expected to exhibit brittle behavior and
