The research concentrated on the corrosion resistance of reinforced self-consolidating concrete (SCC), lightweight SCC (LWSCC), fiber reinforced LWSCC (FRLWSCC), Engineered cementitious composite (ECC) and composite (ECC-SCC/LWSCC) beams. The performance of corroded beams were analyzed based on current measurements, half-cell potential readings, crack pattern/width, rebar mass loss and diameter reduction from accelerated corrosion tests. Corroded and their companion uncorroded beams were tested to failure under four-point loading to evaluate load-deflection response, crack pattern, 1st flexure/diagonal cracking load, failure load and failure modes. Composite beams with higher ECC layer thickness exhibited superior corrosion resistance than their lower thickness counterparts and full depth SCC or LWSCC counterparts as well as performance of beams with ECC wrap was better than those with layer. Overall, ECC beams can be a superior alternative of their conventional counterparts and ECC can be used as layer or wrapping in conventional/LWSCC beams to enhance corrosion resistance and structural performance

“…Due to this, Self-Compacting concrete therefore depends on the material characteristics, their mix proportions and the addition of superplasticizers and/or viscosity modifying agents. One of the most important material differences between Self-Compacting concrete and normal vibrated concrete is the incorporation of high amount of fines, low water binder ratio and superplasticizer usage to achieve its high deformability and stability [3]. It is important to note that the required high amount of fines (powder) has a direct influence on the cost.…”

Self-Compacting concrete is a concrete that is able to flow and consolidate under its own weight, completely fill the formwork even in the presence of dense reinforcement, whilst maintaining homogeneity and without the need for any additional compaction. Self-Compacting concrete is achieved by using high proportions of powder content and super plasticizers. Due to this, pronounced thermal cracking is anticipated. Thermal cracking in concrete structures is of great concern. The objective of this research is to carry out experiments and investigate fresh and hardened properties of SCC developed using a blend of ordinary Portland cement and ground granulated blast furnace slag (GGBFS), to evaluate the applicability of Japan Concrete Institute (JCI) model equations and to find out any similarities and differences between Self-Compacting concrete and normal vibrated concrete-Portland blast furnace slag concrete class B. Thermal stress analysis of the proposed Self-Compacting concrete and normal vibrated concretes were investigated by simulation using 3D FEM analysis. To carry out these objectives, concrete properties such as autogenous shrinkage, adiabatic temperature rise, drying shrinkage, modulus of elasticity, splitting tensile strength and compressive strength were determined through experiments. From experimental results, it was observed that except for the fresh properties, the hardened properties of Self-Compacting exhibit similar characteristics to those of normal vibrated concrete at almost similar water to binder ratios. It was also established that Self-Compacting concrete at W/B of 32% with a 50% replacement of ground granulated blast furnace slag has better thermal cracking resistance than SCC with 30% GGBFS replacement. It is also found that provided the relevant constants are derived from experimental data, JCI model equations can be applied successfully to evaluate hardened properties of Self-Compacting concrete.
