Compressive and Diametral Tensile Strengths<br />
Compressive and diametral tensile are two common measurements of cement strength.<br />
In this test, cylinders of the cement are fabricated, cured (either self-cured or light-cured),<br />
and sectioned to yield either an elongated vertical cylinder or a disc. The elongated cylinders<br />
are compressed to failure along the long axis. The discs are compressed along the<br />
diameter until failure.<br />

The values reported in Figures 17 and 18 show the diametral tensile and compressive<br />
strengths for samples that were light-cured and self-cured. Although slight differences<br />
are noted between the light-cured and self-cured samples, the values were high for both<br />
conditions. Sample size for each group tested is six. Values are reported in MPa. (Note:<br />
to convert these values in MPa to their corresponding values in psi, multiply by 145.0).<br />
