Abstract:
The Alex Fraser Bridge, located near Vancouver, B.C., is the world's longest cable stayed bridge, spanning 465 m. Large quantities of cast-in-place, high-strength concrete were placed, of which 1055 m3 was 55 MPa low-slump, volume batched concrete used in the deck overlay. This article describes the quality-assurance procedures, presents a statistical analysis of the test data, and compares the statistical performance of the volume-batched concrete to weight-batched, ready-mixed concrete of the same strength class.
