Abstract:
BCSA cement is a rapid setting, rapid hardening cement that has been used extensively in pavement repair applications. Concrete made with this cement has also been shown to have excellent structural performance in terms of flexural strength and shear strength. Due to its rapid strength development and low shrinkage, it makes an ideal structural repair material, especially for important infrastructure that cannot be taken out of service for long periods of time. This presentation will detail the mix design development of a self-consolidating concrete (SCC) repair mixture made with BCSA cement. The process of developing this mixture and the properties of the rapid setting SCC will be described. Special considerations required in proportioning SCC with BCSA cement will be explained. Since the desired application of the mixtures is structural repair, descriptions of structural tests of damaged members repaired with BCSA cement SCC will be described and some preliminary results will be shared.
