Electronic waste or e-waste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered as e-waste. Informal processing of electronic waste in

recycled coarse aggregate. Mortar has delaminated from aggregate, and the coarse aggregate doesn't damage. So, the pulsed discharge method can collect the recycled coarse aggregate like the shape of the coarse aggregate. 4.3Table 3 Sample of recycled coarse aggregate Sieve test Sieve test of recycled aggregate were conducted.

The E- waste material is calculated on weight basis as coarse aggregate in the conventional mix: The fineness modulus of coarse aggregate with various E- waste contents is observed as 6.9. The divided particle size is assumed to be between 10mm and 20mm. Then E- waste particles can be considered as partial coarse aggregates.

01-01-2020· In this paper, a detailed study is done on the utilization of E-waste plastic as coarse aggregate in M40 grade concrete with a percentage replacement of 12%, 17% and 22%. The main aim of this experimental work is to utilize the amount of discarded electrical and electronic equipments into beneficial raw materials using environmental friendly technology.

Key Words: Concrete, waste glass powder, coconut shell, partial replacement, fine aggregate, coarse aggregate. 1. INTRODUCTION

2. Separation of the coarse aggregate from demolished waste takes time and labour. 2. LITERATURE REVIEW 1. “Use of demolished concrete waste in partial replacement of coarse aggregate in concrete” SSRG International Journal of Civil Engineering (SSRG-IJCE) – volume 3 In this paper, it is discussed that there is a large amount of

used as one such alternative for coarse aggregate. Owing to scarcity of coarse aggregate for the preparation of concrete, partial addition of E-waste with coarse aggregate was attempted. The work was conducted on M25 grade mix. The addition of coarse aggregate with E-waste in the range of 0%, 32%, 34%, 36%, and 38%. Finally the

In this project Coarse aggregate is partially replaced by e-waste up to 5%, 10%, 15%, 20% and 25%. And so in these mix 10% fly ash is also added by partial replacement of cement and all these mixes are controlled for its compressive strength and flexural strength. II. METHODOLOGY E-waste or electronic waste is collected from local area, this

E-Waste as a coarse aggregate. E –waste (Printed Circuit Boards) was crushed in various sizes and sieved through 4.75mm, 10mm, and 20mm. It was used to replace coarse aggregate (by weight) in concrete at various percentages as listed in Table 1 are taken for the investigation. Concrete Grade of …

2013815ensp0183enspagregate uses ceramic waste as coarse aggregate in the manufacturing of structural grade concrete. Therefore, in the ceramic industry, concrete is named as ceramic waste aggregate concrete. About 30% of the products become waste, and they are not recyclable. At present, ceramic waste is electrical insulator and other wastes

Coarse aggregate: Coarse aggregate having a nominal maximum size of 20mm was used. Water: Fresh tap water was used . Chipped rubber: It is used to replace the coarse aggregate and having the dimension of about 20 mm. The specific gravity of Chipped Rubber is 1.106. following the above same procedure. Fig. 1 Cut piece of waste tyre IV.

As 100% replacement of natural coarse aggregate (NCA) with plastic coarse aggregate (PCA) is not feasible, partial replacement at various percentage were examined [8], [9]. The percentage substitution that gave higher compressive strength was used for determining the other properties such as modulus of elasticity, split tensile strength and flexural strength.
