Abstract:
Discusses the characteristics of high-strength concrete and what is needed to achieve them. Describes the essential role of high-range water-reducing agents (superplasticizers) in providing the workability required to achieve adequate consolidation at the low water-cement (water-cementitious) ratios needed for producing high-strength concrete. Discusses the use of silica fume, fly ash, and ground granulated blast furnace slag; aggregate characteristics and their influence on concrete strength and workability; and the need for cement- superplasticizer compatibility.
