Development of Light-weight Interlocking Block Productfrom EVA Plastic Wastes

Abstract

This research has objective to taking EVA Plastic Wastes from slipper factory as total mass replaced coarse aggregates in produce interlocking block, ratio of cement : stone dust: water supply equal as 1 : 6: 1.5 by weight. Moreover, specify replaced stone dust as EVA plastic waste via sieve no. 4 as follows; stone dust: EVA plastic waste equal as 5.960 : 0.040, 5.955 : 0.045, 5.950 : 0.050, 5.945 : 0.055 and 5.940 : 0.060, respectively. Mixed and casted interlocking block using compressors hand as interlocking block sample, a block size of 12.5 cmx 25 cm x 10 cm, testing according to various standards of TCPS. 602-2547, testingthermal conductivity standard of ASTM C177. Result oftest found that weight per pack, water absorption, drying shrinkage, compressive strength and thermal conductivity has downward trend when mixed EVA plastic waste increasing amounts, respectively. All ratios, with all the criteria set so can taking EVA plastic waste is total mass for mixing replaced stone dust in interlocking block products. It also offers advantages in terms of heat insulation properties than general interlocking block.
