Research of an empirical tests on the use of burned clayey brick refuse as coarse aggregate in the production of concrete are presented throughout this article. The use of native gravel in Basrah, Iraq, in concrete projects as a coarse aggregate has been expanded alarmingly as a result of the faster score of development in structural concrete projects for buildings, houses, and residential complexes. Additionally, as the brick industry has grown, a lot of products have been generated, mostly waste materials that have an adverse effect on the environment, whereas crushed melted brick will be used in concrete as a replacement with gravel for the sustainability purposes. In order to fulfill the objective, many tests of properties (slump, density and compressive strength) were conducted to use melted brick by-product(waste) of clay production as coarse aggregate in concrete performance, also visual examination after concrete were observed to check homogeneity of mix, to enable study the impact of use of crushed melted brick instead of gravel, constant slump 150 mm was maintained for all mixes, reference concrete (normal concrete with natural rushed gravel) compressive strength was constant 48 MPa, the replacement ratios of crushed clayey melted brick was the primary concern. Which were 0, 50 and 100%. The mixing proportions and W/C ratio were constant 0.40 to be able for evaluation and comparison of different mixes. The findings show that, at ages of 7 and 28 days, the mixtures which include molten crushed brick aggregate, exhibit strength losses of roughly (12–17) % and (17–21) %, respectively, when compared to regular concrete. This is dependent on the percentage of brick molten aggregate replacement with gravel numerous 50 up to 100%. Furthermore, the melted crushed brick material is possible utilized as concrete’s coarse aggregate in with considerable medium density about 2100 kg/m3.
