Due to the problems of disposal of waste by-products and depletion of natural construction materials, this research intends to show a promising solution to solve these problems by utilizing waste by-products as viable construction materials. Three different kinds of materials, dihydrate phosphogypsum, by-product aggregate, and incinerator residue, were investigated. The core studies are to evaluate the basic engineering characteristics including durability of these three materials for potential uses in highway and building constructions. To realize the feasibility of utilization of dihydrate phosphogypsum (DPG) as precast building products, the strength properties of DPG-based mixtures subjected to static compaction by various pressures were investigated. In addition, the abrasion resistance of DPG-based mixtures consolidated by impact compaction was also evaluated to show the advantage of DPG used in highway construction. Moreover, the engineering properties of pervious concrete and of high-strength concrete containing by-product aggregate were studied, respectively. The strength properties of concrete using coarse incinerator residue consolidated by vibration and of brick composed of fine incinerator residue compacted by static compaction were also respectively investigated. The encouraging test results obtained in this research indicates that these three waste by-products have great potential for use as construction materials.
