Interlocking Block Product for Community Enterprises from Anhydrite Rock Fragments

Abstract

The objective of this research was to use waste rock of mining anhydrite for developing interlocking block product. Waste rock of mining anhydrite is waste from grind rock process for construction which is coarse aggregates replaced all normal aggregate. Specify ratio mixer is cement per anhydrite waste equal as 1: 6: 0.56, 1: 8: 0.72 and 1: 9: 0.80 by weight, respectively. Mixed and casted interlocking block using compressors hand as interlocking block sample, a block size of 10 cm x 10 cm x 20 cm, testing according to various standards of TCPS.602-2547, testing thermal conductivity standard of ASTM C518. Testing result found when increasing mixed anhydrite volume the dry weight per pack and compressive strength are reduced. While ratio of water absorb is increase and thermal conductivity value is similar in all mixer ratio. Then the conclusion showed that anhydrite waste could be the total mass for produce interlocking block. Their properties reached to all ratio standards and it has insulation properties like interlocking block.
