Therefore, when According to the Environmental Protection Agency, the population grows quickly, more electronic waste is produced. Electronic waste (E- waste) Management Rules, however, are not being properly implemented in the current environment. It has quite substantial environmental effects. Electronic equipment has a finite life span and eventually emits radiation that is dangerous to anyone nearby. E-waste is used in place of construction materials in the civil industry, and Construction Demolition (C&D) waste is also employed to cut costs.
about 15–25% of electronic trash is recycled, with the remainder ending up in landfills or burning incinerators. Because electronic equipment contain harmful pollutants including lead, mercury, cadmium, and beryllium, etc., handling electronic waste in underdeveloped countries poses major health and pollution issues.
Construction and demolition trash is left over after a building has been demolished. In India, the construction sector produces between 10 and 12 million tonnes of garbage per year. In India, recyclable materials including bricks, wood, metal, and books are recycled. About 50% of all debris, including concrete and masonry waste, is not recycled. This issue is solved by recycling construction and demolition debris and using some of it as a coarse aggregate in concrete.
This research work focuses on utilization of Electronic waste and construction demolition waste as partial replacement of coarse aggregate in Concrete and also determine the compressive strength & split tensile strength. We used Printed Circuit Board plate as ingredient in concrete. Also investigating the Changes in the properties of concrete & replaced the aggregate with 5%, 7.5% and 10% of E-waste by weight and Fixed percentage of C&D waste by weight in concrete Key words: substantial environmental radiation, Printed Circuit Board plate

1.Prasanna et al (2014) investigated substituting coarse aggregate with e-waste by 5%, 10%, 15%, and 20% in one batch, and they also prepared another batch with the same ratio of Ewaste and 10% fly ash. When 15% of the coarse aggregate is substituted with e-waste, the concrete strength is determined to be optimal..From this investigation I used to substituting coarse aggregate with e waste by 5%,7.5%,10%.
1.INTRODUCTION Electronic garbage, sometimes known as e-waste, refers to outdated electrical or electronic equipment’s-waste includes used electronics that are intended for recycling through material recovery, refurbishment, reuse, resale, salvage, or disposable-waste processing done informally in developing nations can have a negative impact on human health and cause environmental contamination. Due to population growth, construction activities, and alterations in lifestyle, there is an increase in the amount of plastic garbage in municipal solid waste. Electronic garbage, often known as E-waste, is made up of obsolete, broken-down electronics including TVs, refrigerators, radios, and computers that have reached the end of their useful lives. An estimated 50 million tonnes of e-waste are created annually around the world. India generates roughly 1, 46,180 tonnes of electronic garbage annually.

2.Amiya Akram et al (2015) investigated shredded eplastic and fly ash as a partial replacement for coarse aggregate in two batches, one with e-plastic alone and one with eplastic + fly ash. They substitute coarse aggregate with eplastic by 5%, 10%, and 15% in one batch. They examine the concrete's compressive and flexural strengths. They discovered that adding E-plastic to concrete increases compressive strength but decreases flexure strength since the specimen breaks without making a sound in the flexure strength test because it became less brittle.From this investigation I
