EXPERIMENTAL INVESTIGATION OF TENSILE AND FLEXURAL STRENGTH OF CERAMIC WASTE CONCRETE

Abstract

Different types of ceramics products are available in the market, which are being
used for a wide variety of applications. Bricks, tiles, sanitary wares, sewer-pipes, pottery etc. are
the common examples of ceramic products. The wastes generated from different products have
constituted a serious adverse environmental impact in the societies. Therefore, use of ceramic
waste as partially replacement material of any of constituents of the concrete, will not only control
the product waste tactfully but will also economize concrete manufacturing cost. Moreover
depleting sources of sand in Pakistan triggered the dire need of replacement of fine aggregate of
the concrete. Experiment research was conducted to investigate the effect on compressive, tensile
and flexural strength of concrete with the use of industrial ceramic waste as a partial replacement
of fine aggregate in the concrete at the age of 28 days. Four types of concrete mixtures were tested
in this research i.e. CC-0, CC-10, CC-15, and CC-20, where CC-0 stands for Reference Concrete
and CC-10, CC-15 & CC-20 stand for concretes having 10%, 15% & 20% ceramic waste as sand
replacement material respectively. Tests for compressive strength, modulus of rupture, split
cylinder and double punch were performed. It revealed that the concrete produced with ceramic
waste has more tensile strength, flexural strength and compressive strength when compared with
reference concrete, which explicitly opened a door to use of industrial ceramic waste in concrete
production.
