Optimize mechanical properties of Oman cement using bio waste of sea shell

EasyChair Preprint 2304

Abstract

This study is used to optimize the quality of Omani cement using sea shells as a bio waste to be employed as an active additives surrogate of fine aggregates. The starting of this work is to collect, clean, grind and burn the shells in the oven at a certain temperature 500 ^oC. Then, prepared five samples of cement and add specific proportions of shell powder properties 0%, 3%, 5%, 6.5%, and 10% by weight of cement and mechanical properties were tested for the compressive force, split tensile strength and flexural strength for all the samples. The experimental results showed that 6.5% is the best sample. Employed numerical mathematical model for the estimate the maximum and minimum percentage of shell powder to increase strength of samples. The optimum of numerical model percentages of seashell powder 2.3%, 2.21% and 6.53% were the optimum in the compressive strength, split tensile strength and flexural strength respectively. It is appeared from this novel technique to apply the active interaction effects between experimental, numerical model and optimization make significantly promotes to reach high quality outcomes.
