properties of lightweight concrete manufactured with fly Ash Furnace bottom Ash and lytag
Proceedings of the International Workshop on Sustainable Development and Concrete TechnologyAmerican Concrete Institute International Northwestern Uni, 2004Co-Authors: R Ibrahim, Muhammed BasheerAbstract:The study used fly Ash (FA), Furnace bottom Ash (FBA) and Lytag (LG) to replace ordinary portland cement, natural sand and coarse aggregate to manufacture lightweight concrete. Two control mixes containing no replacement materials were used as control mixes. The study investigated the density, compressive strength, pull-off surface tensile strength, air permeability, sorptivity and porosity of the concretes. The results indicated that it was possible to manufacture lighweight concrete with various waste materials, but the introduction of FBA into concrete would cause detrimental effects on the permeation properties of concrete.

Durability of autoclaved construction materials of sewage sludge–cement–fly Ash–Furnace slag
Construction and Building Materials, 2013Co-Authors: Jiakuan Yang, Yafei Shi, Yalin Li, Mei Liang, Xiao Yang, Ye Li, Nan YeAbstract:Abstract In the present work, we demonstrate an alternative for the final disposal of sewage sludge by using it as an additive in a mixture with cement, fly Ash and Furnace slag, which can potentially be used to develop newly promising construction materials by autoclave curing. The dewatered sewage sludge is obtained with fly Ash and lime. These physical conditioners contribute to both dewatering process and solidifying/stabilizing of sludge. Various mechanical properties such as flexural strength, compressive strength and the toxicity characteristic leaching procedure (TCLP) were evaluated. To evaluate long-term performance, different types of accelerated attacks, i.e. freezing–thawing cycles, accelerated carbonation, wet–dry cycles, and heat–cool cycles were also determined. The obtained test results were indicated that the autoclaved samples exhibit good long-term performance after evaluations of different durability tests. XRD patterns show that the hydration products of autoclaved samples are katoite and C–S–H phases, which mainly contribute to strength of autoclaved products. Morphologies of autoclaved samples also demonstrate the existence of the gel-like and honeycomb-like hydrated products. The results show that this new construction material could be applied as many construction and building materials, i.e. landfill liners and building blocks.

Effective Utilization of Coal AshES in Road Construction
Studies in Environmental Science, 2008Co-Authors: Kemn’ichi Torii, M KawamuraAbstract:Summary The effective utilization of coal Ashes, which are industrial waste products from coal-burning power stations, as a material in road construction has been assessed. The results have been obtained from a laboratory study of compacted fly Ash-Furnace bottom Ash mixtures stabilized with and without chemical additives. From the results, it was found that the compacted fly Ash-Furnace bottom Ash mixtures stabilized with small amounts of hydrated lime or cement fulfilled the requirements of the strength and the resistance against the immersion in water as base course and structural fill materials in road.
