Mechanical Properties of High-Volume SCM Concretes
Portland cement production is a major source of CO2 emissions worldwide. More sustainable cement-based systems can be developed through the use of supplementary cementitious materials (SCMs) to partially replace cement content. Total cement replaced is often limited due to the slow strength gain that is typically observed in these systems. This research seeks to develop self-consolidating concrete (SCC) containing high volumes of SCM that is applicable for composite construction. Possible composite components that this concrete would be applicable for include concrete filled tubes for structural columns and dual skin composite shear walls to resist gravity and seismic loadings. In these applications, an outside structural steel member is available to take initial loadings as the concrete develops strength. However, the time-dependent behavior of the concrete must be known to predict the performance of the composite system.
