Partial Replacement of Cement, Fine Aggregates & Coarse Aggregate with fly Ash, Steel Slag & Recycled Aggregates Respectively in Concrete

Abstract

Around the world, a sizable number of people are employed in the construction industry. Today, development is occurring at an alarmingly rapid rate, which has led to an increase in the use of building materials that are already present in nature. The majority of the millions of tonnes of trash produced each year around the world is not recyclable. Additionally, recycling trash uses energy and harms the environment. Furthermore, both the accumulation of trash in the suburbs and the disposal of waste pose serious environmental risks. It is acceptable to accomplish two goals simultaneously by using waste material in the production of concrete, including the addition of advantageous properties. For this undertaking the globe. Today, development is occurring at an alarmingly rapid rate. Experimental findings from a study to determine the compressive strength of concrete with various cement replacements as well as fine and coarse particles were presented. An M-20 grade of concrete (1:1.8:3.16) with a water-cement ratio of 0.5 was developed, per IS-10262-2009. The findings show that cement, fine aggregates, and coarse aggregates can all be replaced with fly ash, steel slag, and recycled aggregates at percentages of 10%, 20%, and 30%, respectively, without compromising the concrete's compressive strength. To ascertain how much the strength will be increased, we are altering the materials one at a time. It stops when it reaches a specific percentage. To find out the mechanical properties of concrete, it will be increased and all of the ingredients will be changed at once.
