Uncrushed Cockleshell as Coarse Aggregate Filler Replacement in Concrete
This research aims to look at the effects of using uncrushed cockle shells (UCS) as a coarse aggregate in standard weight concrete (NWC). The local fish called it “blood cockle”, is also known as “Kerang” in Malay. Landfill management issues and air pollution resulted from the disposal of large amounts of waste shells into landfills. As more and more mining activities for building aggregate are carried out, it was critical to investigate new possible materials that could turn waste into useable construction material. Hence, the idea of using waste cockle shells as one possible material is developed. In this study, the coarse aggregate was substituted with 10, 20, 30, 40, and 50% Uncrushed Cockle Shell (UCS). A total of 36 concrete cube specimens were produced in six batches with varying percentages of uncrushed cockle shell replacement. Six concrete cube samples per batch were cast and water cured for 7 and 28 days, respectively, before the compressive strength test. The workability and compressive strength between the Ordinary Portland Cement (OPC) and (UCS) concrete are compared in this study article. A slump cone test was performed on the (OPC) and (UCS) concrete mixtures to observe and record the slump value. Both OPC and (UCS) concrete cube specimens' compressive strength were evaluated. In addition, the best % replacement of cockle shells as coarse aggregate in terms of maximal compressive strength was found. Repurposing aquaculture by-products to replace natural aggregates would be a brilliant concept. However, putting this theory into practice is difficult since more supporting data are needed.
