An Investigation of Mechanical Properties of Concrete by Applying Sand Coating on Recycled High-Density Polyethylene (HDPE) and Electronic-Wastes (E-Wastes) Used as a Partial Replacement of Natural Coarse Aggregates

Plastic wastes are a major hazard for the environment and their use in construction industry is increasing day by day. The drawback of plastic concrete an exceptional reduction strength workability. This research work explores effect sand coating on two types recycled aggregates, high-density polyethylene (HDPE) electronic-wastes (E-wastes), as partial replacement natural aggregates. ranged from 0% to 30% along with super plasticizer SP-675 wet lock sealant. Both aggregates crushed, melted, ground convert them into 20 mm size. workability containing uncoated (HDPE electronic wastes), SP-675, sealant has been found be higher than controlled samples Compressive strength, split tensile flexural such type lower due weak bond between Ordinary Portland Cement. After applying improve bonding, reduced compared whereas compressive coated aggregate concrete. There significant increase after addition when added 2% weight cement. positively affects properties It recommended that durability further explored future studies.
