Performance of Recycle Aggregate Concrete Two-Way Slabs : LAP Lambert Academic Publishing : 9786206143628 : 6206143627 : 19 Apr 2023 : The importance of the investigation is to encourage the utilization of recycled coarse aggregate concrete for construction works. Presently the construction sector is facing a shortage of sand and M-sand came into the market as an alternative material for natural sand. State and Central governments are encouraged to use it for construction activities. Similarly, over wheeling of natural resources, a shortfall can be expected in feature for coarse aggregate also. Hence, the adoption of recycled aggregate is necessary for concrete works to provide a sustainable environment. The present research aimed to investigate punching shear capacities for slab elements with the incorporation of recycled aggregate in place of natural aggregates and study was extended with addition of different fibers (steel, glass, basalt and polypropylene).
