Setting Time and Sem Analysis For Cement Mortar Containing Partial Replacement Of Fine Aggregate By Green Sand And Bottom Ash
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Cement, Sand and Aggregate are essential need for construction firm. Consumption of cement is high, due to large use of concrete and mortar. Cement, sand and aggregate are basic needs for any construction industry. Sand is a prime material used for preparation of mortar and concrete and which plays a major role in mix design. Now a day’s erosion of rivers and considering environmental issues, there is a scarcity of river sand. The non-availability or shortage of river sand will affect the construction industry, hence there is a need to find the new alternative material to replace the river sand, such that excess river erosion and harm to environment is prevented. Many researchers are finding different materials to replace sand. Using different proportion of green sand and bottom ash along with sand the required concrete mix can be obtained. One of the best method to overcome this consumption is usage of alternative material, instead of sand. The ultrafine bottom ash and green sand was used here, as a replacement of sand. The 30% of sand was replaced by using both bottom ash and green sand. Setting time, cube compression test, split tensile test were studied for the replacement of bottom ash and green sand. Scanning Electron Microscopy (SEM) applied to investigate the micro structural behaviour and chemical element distribution, inside cement- binder matrix. Further, the replacement of bottom ash and green sand with sand will be analysed by testing the initial setting time, final setting time, compressive strength and split tensile strength.
