Development of Construction Materials from Waste Rock of Mining Andesite for Technology Transfer to Local Communities

Abstract

This research aims to develop the production, ratios, physical properties, mechanical properties, and thermal insulation of construction material products that are used andesite rock fragments as aggregates. The 4 research of construction materials include concrete, concrete block, interlocking block, and paving block which compare to general construction materials. The results found that andesite rocks fragments construction materials have production and ratios as same as general construction materials. The physical and mechanical properties of andesite rock fragments construction materials that density, strength, and thermal insulation are lower than the general construction materials. While the water absorption of andesite rock fragments construction materials are higher than general construction materials. However, all the andesite rock fragments construction materials can pass the standard and use as same as the general construction materials. The results are transferred and applied to local communities.
