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 »

Concrete in Brief

Concrete in Brief Properties of concrete Easily mixed, handled, transported, placed in position and compacted Segregation Separation of constituent materials of concrete Creates larger voids and reduces the durability and strength. Bleeding Water from concrete comes out of the surface Produces pores in concrete and reduces strength. Strength Compressive strength, tensile strength, flexural strength. Elasticity… Read More »

British Method of Mix Proportioning

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

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 »
