Development and testing of chemically based self consolidating concrete

Abstract

"Self-consolidating concrete (SCC) possesses several characteristics that can benefit the concrete construction industry including accelerated construction, a reduction in labor and equipment, and a reduction in construction noise through eliminating or reducing the need to vibrate the concrete. However, SCC has some potential downsides. These problems can usually be attributed to higher paste content, higher fines content, rounder aggregate, and higher water to cement (w/c) ratios used to increase the flow of the concrete. The goal of this research project was to develop a SCC that had improved material properties through the use of chemical admixtures instead of modifications to the mix proportions. After the SCC was developed, the material properties were compared to a more traditional or normal concrete (NC) mixture.

Both the SCC and NC underwent testing of fresh and hardened properties. The SCC underwent the following tests: slump flow, J-ring, L-box, and segregation column. These tests aided with mixture proportioning and optimization. After the SCC mix design was selected, material properties were tested and compared for both NC and SCC. These tests included: compressive strength, modulus of rupture, shrinkage, and shear strength. These properties were compared between the two types of concrete and also with empirical models and design code provisions"--Abstract, page iii.
