The use of self-consolidating concrete (SCC) can contribute to increased productivity, an improved working environment, and improved concrete mechanical behavior and durability. However, use of SCC is still generally low, mainly due to the high cost associated with the high cement content and admixtures. The effective reduction of cement and cementitious materials contents in SCC mixtures will reduce cost and also minimize environmental impact. Among other benefits of reduced cement content leading to reduced paste content is reduced concrete shrinkage and thereby reduced risk for crack-formation. This section includes presentations on the benefits, design, and performance of SCC with low cementitious materials content.
Learning Objectives:
(1) Define the principals of using lattice effect and packing density of aggregate for mixture design of Eco-SCC and mixture design protocol for SCC with relatively low binder content;
(2) Identify the value of using high volume of supplementary cementitious materials and fillers to enhance performance of SCC;
(3) Summarize the use of recycled concrete aggregate and low binder content on performance of SCC;
(4) Explore avenues to increase robustness of Eco-SCC and Extreme SCC.
