Also, every year huge quantity of concrete is used for building construction in Oman. In this project work, iron waste was collected from Sohar steel plant and was mixed with concrete. The aim of this study is to determine the mechanical properties of concrete with iron waste to be compared with normal concrete. The percentages of iron waste can be added to concrete as 0%, 10%, 15% and 20% were based on literature review. For experimental work, cubes were casted with iron waste. Also, slump test was conducted to measure the workability of fresh concrete. Furthermore, density of concrete with and without iron waste was determined. Finally, compressive strength test of concrete cubes was done for C30 grade concrete. Test result shows that compressive strength is reducing by increasing iron waste percentage.</span></p> Aravind Namasivayam Maryam Salim Al Jardani ##submission.copyrightStatement## 2018-03-07 2018-03-07 2 1 29 33 Sizing and Economic Analysis of PV-Diesel Hybrid System with HOMER Software <p>Renewable energies are increasingly shown as the most important solution to a rising universal population demanding reasonable access to electricity while reducing the need for fossil fuels. Egypt possesses an abundance of land and sunny weather, making it a prime location for renewable energy sources. Egypt intends to supply 20 percent of generated electricity from renewable sources by 2022.This paper discusses the optimized sizing and the economic analysis for PV –Diesel system at El-Sheikh Zayd city in Egypt, the software used is homer software</p><p>For this study, The load is 200 kW AC work 24 hours every day, this has scaled up the annual peak load to 216 kW peak. The optimization results show that PV-Diesel-battery based power system is economically more practicable with a minimum total NPC of $ 60.160.159 and a minimum COE of $.330/kWh.</p><p> </p> Heba S.
