Properly proportioned concrete mixes should be designed to produce (1) quality, (9) workability, and (3) economy. Required quality and adequate workability are mandatory, but to completely evaluate a mix, its cost should be considered. Useful information regarding concrete can be obtained by evaluating concrete mortars. This accomplished by evaluating the mortar from concrete mixes and correlating with concrete tests. New laboratory apparatus used in the study of concrete mortars is discussed. Test results are included in which the following were evaluated: (a) aggregate grading, (b) aggregate particle shape, (c) portland cement, (d) pozzolans, (e) admixtures, and (f) water-cement ratio.
