Interlocking blocks products from granite dust mixed with waste vinyl signs

Abstract

The objective of this research is to study the possibility of using waste vinyl as an ingredient to produce interlocking block products by using the ratio of Portland cement type I to granite dust at the ratio of 1: 3. In addition, we increased more the amount of waste vinyl in a mixing ratio of 0, 1.0, 1.5, 2.0 and 2.5 by weight of composites respectively. The research found that the amount of waste vinyl at the ratio of 1.0, 1.5, 2.0 and 2.5 by weight of the composites with the average compressive strength 66.51, 52.19, 47.22 and 38.03 kilograms / square at ages of 28 days, respectively that passed the community product standard (602/2547) of Ministry of Industry and these interlocking blocks were classified as non-load bearing type. Increasing amount of waste vinyl in the components lead to reduce a compressive strength, density and increase water absorption, but it is useful to insulation. This is another way to reduce the wastes and residues in the environment.
