• Abstract:
  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 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 was collected from ; eighty-four mixtures to show compressive strength variability of gravel aggregate concrete.
