ANOVA statistical analysis for determining the optimum contain of waste powders in concrete

Abstract

Reusing and recycling waste are efficient ways to reduce waste production while dealing with associated environmental issues. The applications still have a lot of opportunity for improvement, though. This academic article discusses recycled glass and eggshell waste used in construction. The impact of these wastes on specific mechanical characteristics was examined. These wastes have been used as powder and partially substituted for cement in concrete. From the results, it was found that utilizing 10 % glass powder (G) with 5 % eggshell powder (E) gave the highest compressive strength by about 16,37 %, 9,63 %, and 10,85 % at 7, 28, and 56 days, respectively compared to the control specimen.  For the same mix, UPV increased by about 14,28 %, 6,66 %, and 6,8 % at 7, 28, and 56 days, respectively compared to the control specimens.  The mix contains 10 % G with 15 % E powders impacted negatively on properties of concrete. The tensile strengths increased similarly to the compressive strengths, as they increased at 5 % E and began to gradually decrease when the compensation ratio was increased. Utilizing G and E wastes in concrete has been evaluated using an ANOVA statistical study. Analysis reveals that these wastes had a substantial impact on the strength and other variations of concrete properties, and the optimal E to be used with 10 % G is 5 %
