Effect of Locally Manufactured Mosaico Tiles Waste on Concrete Strength

Abstract

this study investigates the strength of concrete production from the waste of local mosico tiles, where included the use of two types of coarse aggregate, the first one was natural aggregate used for the reference concrete mix, and the other was imported from local tile factory in Zliten. The tile waste was crushed by manual means. The natural aggregate in concrete mix was replaced by the mosico tiles waste with percentages 0%, 50% and 100%. Several laboratory tests were carried out on coarse aggregate, fine aggregate and tile waste such as sieve analysis test, water absorption test, and conducting tests on fresh concrete represented by operational testing, as well as hardened concrete to know its resistance. The results showed that the higher the percentage of adding residues, the higher the operational degree, and the decrease in concrete was recorded 9, 10.5 and 11 cm according to replacement ratios, respectively. While the results of concrete resistance showed that the decrease in pressure resistance the higher the percentage of adding residues at the time of 7 days, and recorded 28, 16.77 and 14.84 Mpa, in the above mentioned ratios, respectively. From a period of 7 to 28 days the concrete resistance increased with an increase in the percentage of adding residues. It was recorded as 32.63, 21.01 and 18.26 Mpa, where the strength of the concrete with adding of mosico tile residues is poor compared the reference sample.
