Quikrete® Mason Sand. Quikrete ® Mason Sand (BOM #108572) is a fine, dried sand used as a component in masonry mortar when mixed with masonry cement type N, M, S, or O. Masonry sand can also be used for many other applications where a fine sand is necessary.

Standard Proctor Test - an overview

All these results have been obtained using the standard Proctor and modified Proctor test methods. It can be seen from Table 6.1 that the MDD of CS obtained from the standard Proctor test and modified Proctor test is 2185 and 2510 kg/m 3, respectively, and correspondingly about 12% and 20% higher than that of the sand.
