Ultra-high-performance-concrete (UHPC) is generally defined as concrete with a compressive strength greater than 150 MPa. UHPC typically is made with high-strength steel fibers, fine sand, cement, fly ash, a large volume of SF, and a low amount of water (a w/cm ratio less than 0.20).High-Strength Concrete (ACI 363R)One of the primary objectives of ACI Committee 363 during the last few years has been to update and republish document 363R, High-Strength Concrete. This synopsis is based on a full report on high-strength concrete to be published by ACI Committee 363 (High-Strength Concrete). Estimated publication time for the new document is early 2006.

High Performance Concrete TopicJul 30, 2020· High-performance concrete (HPC) is concrete that has been designed to be more durable and, if necessary, stronger than conventional concrete.
