It is found that use of E- waste aggregates results in the formation of concrete which has lesser weight than that of conventional concrete. This study ensures that reusing of E- waste as coarse aggregate substitutes in concrete gives a good approach to reduce cost of materials and solve solid waste problems posed by E-waste.

Concrete recycling is a well-established industry in many countries, albeit limited to the simple crushing of waste concrete and using only the coarse fraction as aggregate. The fine fractions generally remain undervalued, meaning an obstacle for full re-utilization and commercialisation of waste concrete.
Recent studies have shown that the waste glass can be effectively used in concrete either as aggregate (fine or coarse aggregate) or as cement replacement.
M20 Concrete specimens are also designed and produced without the use of E-waste aggregates for traditional specimens. Conducting hardened concrete durability tests like Compression test, Flexural test, Chloride test, Sulphate test and Chemical test have been carried out. The compression strength of E-waste has been evaluated on 7, …
One of the best management practices of E-waste is its reuse in concrete as E-Waste concrete (EWC) which will also be a partial solution to escalating cost of construction material. The significance of this research is to resourcefully use E-waste in concrete by achieving optimum performance by testing physical, workability & mechanical properties.

Furthermore, as compared to control ...
Thus, the research study recommends the usage of e-waste aggregates as a feasible alternative material to replace coarse aggregates for preparing concrete for nonstructural applications.

Abstract. Objectives: To determine the compressive strength of concrete with e-wastes as additives after a curing period of 28 days. Methods/Analysis: Concrete was produced with 1%, 2% and 3% e-wastes utilizing the Printed Circuit Boards (PCB) made as chips using the Class A mixture with the control. The compressive strength was determined.
These equations estimate the reduction in the compressive strength of concrete mixes with e-plastic waste aggregate at 14 and 28 days.

Polymer obtained from discarded E-waste can be effectively used to enhance pavement durability and performance. The present study highlights overall E-waste management and recycling issues followed by a censorious review of various benefits and methods of using E-waste plastic as construction material.
As waste plastic materials have lower bulk density (HDPE plastic: 930–970 kg/m3, PET: 1270 kg/m3) than natural aggregates (2450-2570 kg/m3), increase in the content of plastic aggregate reduces both fresh and dry density of concrete: the reduction is greater with bigger and flakier particles of plastic aggregate. Mechanical properties.
The e-waste management is continually developing many techniques to include the production and disposal of wastes. Growth in development of infrastructure-waste can be reused in concrete against natural aggregate in small proportions so that the strength-related factors will not be affected.
