Investigation of Compressive Strength of Molded Cylinders and Drilled Cores of Concrete.

Abstract

This investigation was conducted to obtain information on methods being used to estimate the 28-day compressive strength of concrete. Its primary purpose was to determine the relation between the 28-day compressive strength of 6- by 12-in. cylinders molded from samples of concrete mixtures from which aggregate larger than 1-1/2 in. had been removed, and that of 6-, 8-, and 10-in.-diameter cores drilled from test structures and containing aggregate graded to 3-in. or 6-in. size. A secondary purpose of the study was to determine the strength relations of 6- by 12-in. concrete cylinders cured in the field and identical cylinders cured in the laboratory under standard conditions.
