Experimental data relating to standard rates of loading are studied on concrete control specimens 28 days after casting. Normal concrete with an oven-dry density in the range 2000-2800 kg/m3 is used for the specimens. The rates of compression are about 0.3 N/mm\*/sec, or a strain rate of about 30 x
