Investigation on concrete with crushed vitrified tiles as coarse aggregates

Abstract

Presently it has become an inevitable option for engineers and builders to adopt alternative construction materials for concrete production. Different types of processed wastes are recommended by IS 383-2016 for use in concrete as aggregate such as slag aggregates, C and D waste and recycled concrete aggregates. At present in India, it is a common scenario that lots are broken vitrified tiles are found unused in the production and application sites and are dumped into the city outskirts, leading to environmental pollution. From the point of view of effective utilization of these potential tile wastes in concrete, this research was undertaken to address several issues of concrete mix proportioning and its characterization. Two grades of concrete namely M25 and M40 are designed as per IS: 10262-2019 and the mix proportions are presented with granite and vitrified tile as coarse aggregates. One complete mix design using conventional granite aggregate, considering trial mixes, is demonstrated using 50% ground granulated blast furnace slag (GGBFS) to explore the complete potential of the code. The effect of vitrified tile aggregates in various proportions namely 20%, 40% and 60% on various properties of concretes are also studied for one trial mix in both M25 and M40 grades. The various tests conducted are slump and compaction factor tests, compressive, split and flexural strength tests, rebound hammer and UPV tests, water absorption and rapid chloride permeability tests and abrasion test. From the test results it can be seen that the proposed method of mix design can be easily extended to vitrified tile aggregates and results obtained are found to be satisfactory. From the test results it is found that the performance of concrete with tile aggregates is comparable and practically acceptable. Finally, it can be concluded that about 20 to 60% of vitrified tiles can be used as an alternative to conventional aggregates ensuring satisfactory performance.
