Abstract

This paper presents the results of experimental investigation into the behaviour of concrete mixed with recycled-based materials as partial replacement of natural sand. Various properties: compressive, split tensile and flexural strength were investigated through either single or combination replacement categories in which glass sand, rubber sand, and recycled concrete aggregate were specifically proportioned. Test results indicate that certain replacement types of possibly achieve sufficient strength and physical behaviour to replace normal concrete. Single replacements typically generate higher compressive, tensile and flexural strength than combination types. Concrete with lower content of alternative material exhibited comparable strength relative to the original concrete. The workability of higher angular surface material such as glass sand and rubber sand generated higher workability. Keywords: concrete strength; glass; rubber; particles; replacement

Abstract

The degradation in environmental grade and generating concrete with low level of ordinary Portland cement have emerged intention for researchers to produce concrete with slag-based substitutional material. The utilization of slag as a partial substitution of cementitious material in concrete has encountered the need of more sustainable materials in the concrete technology. In contrast, the application of non-ferrous slag (NFS) as substitution of the ordinary Portland cement is not well focused despite the largely global slag deposit and the application in concrete technology. Worldwidely immense deposit of various non-ferrous slag from mining and manufacturing process can be used in generating high performance concrete. On that account, this paper provides a critical review of recent studies concerning the non-ferrous based slag as the substitution of regular Portland cement. Production techniques, properties and the applications of NFS for high strength concrete are also examined. Cement with nickel and copper slag addition with high silica content has the potential to increase concrete durability with proper curing method due to better hydration process and low porosity. The maximum 15% non-ferrous slag addition in total cement weight at high water cement ratio increases concrete compressive strength by up to 30%. Substitution of non-ferrous slag for the ordinary Poertland cement in concrete has great potential to overcome stock waste issues, to reduce carbon dioxide emission and consequently reduce global energy consumption as an environmentally friendly approach.

Abstract

Vertical cracks and spalling of the concrete cover in reinforced concrete structures are examples of failure modes of concrete columns due to repeated earthquake loads. Strengthening methods have been introduced including external jacketing using costly carbon FRP. This study investigated external strengthening of cylindrical concrete using low-cost thin steel confining sheets subjected to concentric axial loads. The experimental works in this study tested the tensile strength of the confining steel elements, the compressive strength of unconfined and confined cylindrical concrete. The composition of the steel confining elements is positioned in such that it could generate an optimal confinement effect and prevent local buckling. This study also developed the formulation of the confining stress and ultimate axial load based on the test results of the current study and past research data. The results showed that the use of steel clamp elements improves the axial strength and axial deformation of cylindrical concrete columns by over 200% without buckling of the clamp elements. The external confinement method can reduce vertical cracks and strain localization that usually occur in conventional cylindrical concrete. The proposed formulation of the confining stress and the ultimate axial load provided accurate results compared to the experimental results.
