Description Concrete is composed principally of aggregates, aportland or blended cement, and water, and may containother cementitious materials and/or chemical admixtures. Itwill contain some amount of entrapped air and may alsocontain purposely entrained air obtained by use of an ad-mixture or air-entraining cement. Chemical admixtures arefrequently used to accelerate, retard, improve workability,reduce mixing water requirements, […]

Description To predict the strength and serviceability of reinforced andprestressed concrete structures, the structural engineer requiresan appropriate description of the mechanical properties of thematerials, including the prediction of the time-dependantstrains of the hardened concrete. The prediction of shrinkageand creep is important to assess the risk of concrete cracking,and deflections due to stripping-reshoring. As discussed inACI
