Influences of Cement Source and Sample of Cement Source on Compressive Strength Variability of Gravel Aggregate Concrete

The strength of concrete is influenced by each constituent material used in the concrete mixture and the proportions of each ingredient. Water-cementitious ratio, cementitious materials, air content, chemical admixtures, and type of coarse aggregate are important factors that influence strength. Experience shows that variability of concrete strength is inevitable even when these factors are held constant. All constituent materials change with each sample of the material and these changes have influence on concrete strength. This study provides the Mississippi Department of Transportation (MDOT) engineers with compressive strength data on gravel aggregate concrete using seven portland cements and three samples collected approximately one month apart from each source. Crushed limestone was used for control mixtures. Data were collected from eighty-four mixtures to show compressive strength variability of gravel aggregate concrete.
