STUDY ON USE OF CERAMIC WASTE AS PARTIAL REPLACEMENT OF FINE AGGREGATE IN CONCRETE

Abstract

The main objective of this final year research project about “Study on use of ceramic waste as partial replacement of fine aggregate in concrete” was to study and evaluate the possibility for replacement of fine aggregates by ceramic wastes in concrete.Following the fixed methodology and with set specific objectives, the study identified the current problems related to the use of fine ordinary aggregates, on one side and to the future disposal of ceramic wastes due to manufacturing industries, on the other side. Through testing, it was first established that the properties of ceramic wastes were adequates for replacement of fine aggregates. This research presents strength parameters and behavior of concrete where natural sand has been replaced partially by ceramic waste.This research is done to enhance the strength and durability of concrete. in addition to the strength, the continuous extraction of natural sand is a big challenge to the future of well-being because it will not only make the aggregate expensive but also degrade the environment. In the project, laboratory test was done to check the strength of different concrete components such as sand, ceramic tile waste, coarse aggregate and also resulting cubes to test their compressive strength. The designed concrete with ceramic wastes tested using The specimen for prepared cube were tested for compressive strength at 7,14 and 28 days with different replacement of sand by ceramic wastes for 0,5,10 and 15% of ceramic tile waste showed good results with 5% of replacement. The test result of compressive strength during 28 days of curing for the successful waste replacement of 5% were 22.88MPa compared to 22 MPa for convention concrete. The split tensile test results during 28 days of curing for the successful waste replacement of 5% were 3.18MPa compared to 2.82 MPa for convention concrete. The test result of flexural strength test result during 28 days of curing for the successful waste replacement of 5% were 5.97 MPa compared to 5.67 MPa for convention concrete.Regarding the cost the study showed that as the cost of one block for both concrte differe only at 1.6% the clear benefit would depend on the importance of the relevant construction.The analysis of test results shows that the practical percent where the sand has been replaced partially by ceramic tile waste is 5% which may be recommended for structural concrete works.
