An Experimental Study on Use of E-Waste Materials in Concrete for Rigid Pavements

Anupam Kumar Sharma, Nitin Dutt Sharma

Abstract: E-Waste can be defined as discarded computers, office electronic equipment, entertainment electronics device, mobile phones, television sets, and refrigerators contain potentially harmful components such as lead, cadmium, beryllium, or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and communities in developing countries. These E-waste are easily used in concrete of rigid pavement because at this time in India construction of Rigid pavement at a larger Scale. Rigid pavements are generally used in constructing airports and major highways. They commonly serve as heavy-duty industrial floor slabs, port and harbor yard pavements, and heavy-vehicle park or terminal pavements. Offering high quality riding surfaces for safe vehicular travel, they function as structural layers to distribute vehicular wheel loads in such a manner that the induced stresses transmitted to the sub grade soil are of acceptable magnitudes. Portland cementconcrete (PCC) is the most common material used in the construction of rigid pavement slabs. Rigid pavements must be designed to endure frequently repeated traffic loadings. The typical designed service life of a rigid pavement is between 30 and 40 years, lasting about twice as long as a flexible pavement. From last few years, we have been discovered that by adding different E-waste replacing coarse aggregate by E-waste in a specific percentage increase or does not affects the mechanical properties of the PCC. During this experimental work the E-waste is used in 2 %, 4 %, 6 %, 8 % and 10 % by weight replacing the coarse aggregate. Several specimens are tested of M40 grade for the analysis of compressive, flexural and tensile strength and result were compared with the controlled mix of concrete and by doing so we reduce the problem of environmental and human hazardous and solve the solid waste problems. The compressive strength at 0 %, 2 %, 4 %, 6 %, 8 % and 10 % were found to be increase 11.11 %, 10.01 %, 9 %, 2.5 % and decreased 2.75 % and 12.5 %. But we observed that up to 10 % replacement of coarse aggregate with Electronic Waste (PCB) the compressive strength decreases, The flexural strength at 0 %, 2 %, 4 %, 6 %, 8 % and 10 % were found to be increase 3 %, 2.68 %, 0.9 %, and decrease 1.65 %, 3.07 %, and 9.55 and The Split tensile strength at 0 %, 2 %, 4 %, 6 %, 8 % and 10 % were found to be increase 13.375 %, 11.9 %, 7.95 %, 2.55 % and decrease 2.575 % and 11.675 %. the Based on these experiment we concluded that the waste generated by the Electronic waste (PCB) can be used as an alternative for the natural crushed stone used in concrete cubes as the compressive strength, and the flexural strength of the testing blocks does not shown any major difference with its original standard mix concrete
