High Performance Lightweight Concrete--a Review

May 01, 1995  The intrinsic nature of lightweight concrete is to produce a material which, in addition to having high strength, can also have high performance in severe service conditions. The reason for high performance is examined in light of physical, chemical, and mechanical properties of the vesicular aggregate used to produce lightweight concrete.

High Performance Concrete - an overview ScienceDirect Topics

For a continuous bridge, the number of piers can be reduced. In many infrastructure projects, high-performance concrete is chosen for its durability against various types of chemical (e.g., sulfate or chloride) and physical attack (e.g., abrasion). High-performance concrete can also be produced with lightweight aggregates.
