Abstract

This research investigated the utilization of label waste by using limestone powder-cement as binder. Physical and chemical characteristics were determined such as particle size distribution of aggregate, leachability, compressive strength, density and water absorption. The appropriate aggregate replacement with label waste was at 3.0% by weight of binder, water-binder ratio was at 0.5 by weight and a curing time of 28 days. The proper concrete paving block; had a compressive strength of 55.7 MPa which yielded the physical properties acceptable by the standard of interlocking concrete paving block promulgated by the Ministry of Industry. The cost estimation of the aforementioned concrete paving block was at 4.36 baht per 4.24 kilograms of product.
