compressive strength of cement mortar in Mexico
CORRELATION BETWEEN COMPRESSIVE STRENGTHS …
3.1. COMPRESSIVE STRENGTH The compressive strength of fly ash cement mortar with different water-binder ratio is shown in Figure 1. The compressive strength of mortar was decreased due to the addition of fly ash, especially the strength at the end of 3 and 7 days, and the strength reduction was greater with the increase of fly ash content.
