ABSTRACT

Due to the fact that many buildings constructed in recent years have intricate architectural designs, compacting concrete with crowded reinforcement is a task that is fraught with difficulty. Self-Compacting Concrete, also known as SCC, is an innovative type of high-performance concrete that has outstanding deformability and segregation resistance. Additionally, it is able to flow through the cracks, corners, and joints of reinforcement without undergoing any vibrations or compaction. 1986 marked the beginning of its development in Japan. In contrast, the use of SCC is extremely limited in our nation compared to that of other nations, such as Japan and many countries in Europe, for example. The construction sector is experiencing a significant amount of difficulty in terms of the availability of natural resources. In order to find a solution to this problem, we will have to look for new materials to replace the traditional aggregate. Recycling of industrial by-products like fly ash and copper slag is becoming more of a focus in recent study because to increased awareness of environmental concerns. For the purposes of this exploratory investigation, the M60 grade of concrete will be utilized. Fly ash and copper slag, in their respective places, are used to partially replace the cement and the fine aggregate. Fly Ash will be substituted for 5%, 10%, 15%, 20%, and 25% of the weight of cement, respectively. Copper slag will be substituted for varying percentages of the weight of fine aggregates, such as 10%, 20%, 30%, 40%, and 50%. These percentages will be determined based on the overall cement weight. An investigation will be conducted to determine the compressive strength, flexural strength, and split tensile strength of hardened concrete with a variety of substitutes. In addition to these, the slump cone, V-funnel, L-box, and J-ring tests will be carried out.
