Paper Title
Flexural Behaviorof RC Two Way Slabs Made with Crushed Melted Bricks as Coarse Aggregate

This paper provides the results of an experimental investigation into the use of crushed melted clay brick waste as coarse aggregate in producing concrete. Fast development in the structural concrete constructions has increased; therefore thehigh consumption of gravel as a coarse aggregate in concrete works has increased in alarming rate. Furthermore, the growth of the brick industry has also produced lots of product mainly the waste materials affected on the environment, so that the production of concrete with crushed melted brick as a suitable aggregate will face the countries in the coming few years and affect its sustainability and economy.In order to fulfill the objective, there are tests that were conducted to determine concrete performance, such as compressive strength test, flexural test, and modulus of elasticity test. The data were collected and analyzed to satisfy the study on melted brick waste as an alternative in coarse aggregate as a partial or full replacement in concrete production. To study the effect of using themelted brick on structural behavior of concrete, five reinforced concrete slabs were tested, the variable was, the replacement ratios of crushed melted brick 25, 50, 75, 100 % of total coarse aggregate, the mix proportions and W/C ratio were constant. Behavior of slabs under loading was observed, cracking and ultimate strength and deflections were recorded. The results reveal that the mixes withmelted crushed brick aggregate show theconcrete compressive strength about(3-13)%, flexural strengthabout (11-33)% and modulus of elasticityabout (10-15)% than gravel concrete,at age of 28 days depending on the ratio of crushed melted brick replacement. Slab with replacement ratio 25% exhibit ultimateload95% the ultimate load ofreferenceslab made with gravel. The results also indicate that the ultimate load of full melted brick waste concrete has achieved 80% of ultimate load of reference slab. Keywords- Crushed melted clay brick, Concrete slab, Flexural behavior, Raw materials.
