Aci Method Of Concrete Mix Design: A Parametric Study ABSTRACT: Concrete mix design by the ACI method requires various material properties as the input. The effect of variation of these input parameters on mix proportions has been studied here, with reference to strength attainment in few cases. The sensitivity of the mix has been expressed … Read more
Concrete Mix Design Concrete is a construction material composed of : Cement (commonly Portland cement) as well as other cementitious materials such as fly ash and slag cement. Aggregate (generally a coarse aggregate such as gravel, limestone, or granite, plus a fine aggregate such as sand). Water and Chemical admixtures. The word concrete comes from … Read more

British Method of Mix Proportioning Current method of mix design of concrete is that revised by Dept. of environment (UK) in 1988. British Method recognizes the durability requirements of mix selection. The design is applicable to normal weight concrete made with Portland Cement only or Blast furnace slag/fly ash. Refer the ppt attached for step … Read more
Aci Concrete Mix Design ¨The most common method used in North America is established by American Concrete Institute. Economy– The material cost are most important in determining the relative costs of different mixes. Since cement is more expensive than aggregate it is clear that cement should be minimized. Workability A good mix design must be … Read more
