Conversion grade of cement gypsum mortar and traditional mortar

The compressive strength of mortar cube is the arithmetic average of the measured values of six specimens as the compressive strength value of this group of specimens, and the average value is accurately calculated to 0. 1MPa. When the difference between the maximum or minimum value of six specimens and the average value exceeds 20%, the average value of the middle four specimens is taken as the compressive strength value of this group of specimens.

The strength of 1: 2 is 23.87MPa.

The strength of 1: 2.5 is 25.87MPa.

Apply 1: 2.5 mortar.
