In this study, different sandstone aggregates and same cement type and dosage may produce different strengths at the different water/cement ratio (Table 4, Table 6). As seen in Fig. 1, water–cement ratio reduces the strengths of concretes, highest water–cement ratio cause lowest compressive and splitting tensile strength.Web
Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch sieve.Web
However, the most common mortar mix ratio for type N is 1 part cement, 1 part lime, and 5 to 6 parts sand. Type O. Type O is the next most common mortar type that sees use almost exclusively indoors.
