This research work is related to the use of environment friendly materials like fibers of coir, polypropylene and jute in concrete. An economical reinforced concrete is produced by reducing the diameter of steel bar by using fiber ropes. We have examined the compressive and flexural strength of fiber-reinforced concrete. In this study, concrete mix is prepared by using coir fibers. Although instead of using only conventional steel bars, reinforced concrete behavior was investigated with the combination of polypropylene fiber and jute fiber ropes along with steel bars for a constant water binder ratio. These fiber ropes are wound around steel bar with the help of Zepoxy 300 for proper bonding of fiber ropes and steel bar. The results demonstrate that properties of concrete are enhanced by using fibers. Fiber ropes with steel bar in coir concrete increased the flexural strength and compressive strength by 6 and 7%, respectively. Furthermore, it is observed that the addition of fibers in concrete changes the cracking pattern of reinforced concrete beams.

Pakistan is on verge of facing severe water scarcity issues by 2025. An exponential increase in population increases the water demand as most of the population in the country depends on groundwater. Over extraction of groundwater is causing depletion in the groundwater table at an alarming rate. Water conservation is becoming the need of time. Rainwater Harvesting is one the best methods that can be used to conserve water. This paper aims to determine the total volume of water that can be conserved from Rainfall on the Rooftop at the University of Faisalabad, Amin Campus located in an industrial city Faisalabad, Pakistan. For this purpose, water usage on the campus is estimated. The area of the campus rooftop is measured by conducting a topographic survey. Rainfall data from the year 1981-2021 is collected and average monthly rainfall is calculated. The soil Conservation Service Curve Number method is adopted to calculate the run-off. Results indicated that about 1300 cubic meters of water can be conserved per year which will cover about 20-25 percent of the total water demand of the campus if a Rainwater Harvesting System is installed at the campus.Keyword: Rainwater Harvesting, Water Conservation, Water Scarcity
