Abstract - Cement is always a valuable material in the construction industry. Because of the massive development of infrastructure, there is currently a shortage of concrete materials, so we must develop alternatives to concrete. The aim of our current study is to partially replace cement with groundnut shell ash (GSA) and GGBS and also coarse aggregate is partially replaced with E-waste (Waste Printed Circuit Boards). In this experimental study, cement is replaced by 0%, 5%, 10%, 15%, 20%, 25%, 30% percentage with GSA and GGBS by weight. Results show that use of 15% GSA and 15% GGBS gives as optimum result so 30% use of cement can be reduced. Then using optimum mix, four mixes of concrete with replacement of natural coarse aggregate by (0%, 5%,10%,15% and 20%) Waste Printed Circuit Boards (WPCB) are carried out. Tests are conducted for coarse aggregates, workability of fresh concrete (Slump test and compaction factor test), strength of hardened concrete (Compressive strength and Split tensile strength test) and nondestructive testing for hardened concrete for M20 concrete using IS method. Test results indicated that the use of 15% GSA and 15% GGBS partial replacement of cement in concrete with use of 10% replacement of natural coarse aggregates with WPCB resulted in improvement in mechanical strengths and can be effectively used in structural concrete. Later at 15% and 20%, the compressive strength and split tensile strength of the concrete goes on reducing.
Groundnut shell is an important cash crop produced in large quantities in India. The groundnuts production volume amounted to about 10.14 million metric tons in the country during fiscal year 2022, down from 10.25 million metric tons in fiscal year 2021[1]. The utilization of groundnut shell ash will promote waste management at little cost and reduce pollution by these wastes.
1.2 SCOPE OF THE STUDY In our country, there is a shortage of materials due to the increased development of infrastructure [2]. Also, production of one ton of cement emits one ton of carbon dioxide to the environment. Keeping in view, this study is focussed on reducing production of cement and also reducing disposal of waste generated from various fields like agriculture and industries [2]. In this project, we have replaced cement partially with Granulated Ground Blastfurnace Slag (GGBS) and Groundnut Shell Ash (GSA) and coarse aggregate with Waste Printed Circuit Boards (WPCB). Groundnut is the major crop in India. Hence there is a large amount of groundnut shell available as a waste. The replacement of cement with GSA not only reduces pollution caused by cement, but also helps in management of groundnut shell waste.

1. INTRODUCTION
The huge increase in construction activities has resulted in depletion of raw materials. In addition to that production of cement remains the major cause for pollution. Hence many researches have been conducted to find out the materials which can be used as the best substitute for the conventional concrete materials. To address the aforementioned problems faced by the concrete industry, and to make it more sustainable, the use of WPCB as the replacement of coarse aggregate has been adopted with great success over past few years. Use of the waste materials not only helps in getting them utilized in cement, concrete and other construction materials, but also has numerous indirect benefits such as reduction in landfill cost, saving in energy, and protecting environment from possible pollution
Global consumption of concrete is second solely to water. There is massive development of infrastructure in developing countries like India, due to which there is increased demand for raw materials. Also huge quantities of agricultural and electronic wastes are generated every year in India. The predominant component used in concrete is cement. The increase in demand of cement accounts to the increased price for cement. However, the manufacturing of cement poses a threat to the environment. Over the years, many waste materials like fly ash and ashes produced from various agricultural wastes such as palm oil waste, rice husk ash, millet husk ash have been tried as pozzolana or secondary cementations materials.
