A Comparative Study on Thermal Insulation Properties of Partial Replacement of Fine Aggregate by E-Waste Material (FR-4) in M₃₀Grade with Conventional Concrete

Abstract:

The purpose of this experiment is to analyze the steady state condition in a concrete slab. Temperature measurements were made for each scenario and were used along with physical dimensions to compute various heat transfer parameters. In this paper, the investigation was made by the partial replacement in the coarse aggregate with E-waste (PCB cutting waste) (FR-4) in the conventional concrete. The durability test such as compressive strength test, split tensile and flexure strength were made and the results analyzed. The investigation is made by casting slab panels of various thickness (1’ x 1’ x 0’-2”, 1’ x 1’ x 0’-4”, 1’ x 1’ x 0’-6”, 1’ x 1’ x 0’-8” & 1’ x 1’ x 0’-10”) with same area and different temperature. These panels were allowed for curing of 28 days and tested in a closed chamber. The heat was transferred from one part of chamber to another chamber through the slab element. Then the heat transformation and U-factor will be calculated and the insulation properties of the e-waste concrete with conventional concrete
