Testing The Use Of Phosphate Materials And Glass Fines In Concrete Production

Abstract

The research focuses on the testing production of concrete through comparison with control concrete mix for phosphate materials from two sources (Al Shedyah and Abiad mining plants) and glass fines that were used in replacement with fine sand in concrete mix on specific mixing ratios (15%, 30%, 45%, and 60%). The program of concrete testing included fresh concrete properties (slump), and hardened concrete properties (unit weight, compressive, tensile, and flexure strengths). The results were sorted through calculating of averages, standard deviations, and analysis using ANOVA and box plot to test the difference in samples averages. Results showed slump of concrete increases with the increase of phosphate or glass fines ratios. Generally, unit weight is stable using phosphate materials, and decreasing using glass fines materials. The initial analysis of compressive strength showed stability, similar talk can be withdrawn on flexure strength, but tensile strength decreases with increase of material ratio in concrete mix. Similar indication can be withdrawn on unit weight of concrete. But for slump value, it increases with the increase of materials ratios in concrete mix. All properties were tested and reported at 28-day period in current research. Also, a box plot was presented for all properties studied in current research to show the range of properties versus the ratios of phosphates and glass fines materials. Also ANOVA analysis was conducted for the properties of fresh and hardened concrete. ANOVA analysis showed that slump values are significant different and null hypothesis is rejected, but for unit weight null hypothesis is accepted that the unit weight is not significant different. Also, results of ANOVA analysis showed that for compressive, tensile and flexure strengths are significantly different and null hypothesis is rejected accept for 60% mixing ratio of phosphate and glass fines, the results are equal and the null hypothesis is accepted. The results of current research presented a different procedure to document, test, and interpret results to be used in future extend of research.
