AbstractAbrasion resistance is one of the most important durability properties of concrete. Especially, highway, airport and industrial floor pavements should be resistant to abrasion. Recently, many research studies have been carried out on the utilization of industrial by-products in concrete. Granulated blast-furnace slag (GBFS) and bottom ash (BA) are two of these by-products. BA is not generally utilized in concrete and has a limited usage. It is mostly dumped, leading to additional costs and environmental problems. On the other hand, both GBFS and BA have potential for concrete production to provide sustainability. They can substitute fine aggregate thanks to their positive effects on concrete durability. Therefore, the aim of this study was to investigate the abrasion resistance of concretes produced with GBFS and BA substituting fine aggregate. Three different concrete series were produced by replacing fine aggregate with GBFS, BA and both of them by mixing them at equal ratios. The replacement ratios of by-products were 10%, 20%, 30%, 40% and 50% by volume. Compressive strength and Bohme abrasion tests were conducted on series. Results were compared to each other. It can be said that abrasion resistance can be improved by these by-products.

This work aims to investigate the effect of additional flue gas desulfurization gypsum (FGDG) on the properties of calcium sulfoaluminate cement (CSAC) blended with ground granulated blast furnace slag (GGBFS). The hydration rate, setting time, mechanical strength, pore structure and hydration products of the CSAC-GGBFS mixture containing FGDG were investigated systematically. The results show that the addition of FGDG promotes the hydration of the CSAC-GGBFS mixture and improves its mechanical strength; however, the FGDG content should not exceed 6%.

AbstractIn developing countries like Pakistan, Due to rapid growth and population, an increase in the production of industrial waste is rising significantly day by day. Stabilization of soil using those industrial wastes not only gives proper usage of waste materials but also increases the cost-benefit ratio as a whole. In this research work, an attempt was made to use Ground granulated blast furnace slag (GGBFS) in the stabilization of District Khairpur Mirs’ soil. Generally, while dealing with building construction industry such as foundations for buildings, highways such as subgrades as a foundation and in earthen dams as landfills sometimes there exist naturally occurring unsuitable soils. District Khairpur Mirs’ soil is accounted for the different laboratory tests and the concerned District Khairpur Mirs’ soil found to be relatively unsuitable; therefore, various percentages of ground granulated blast furnace slag were added to make it suitable. To improve the concerned soil different percentages of slag are used, and samples thus formed so for were tested in the laboratory for this research work. Various laboratorial tests like particle size distribution, Atterberg limits, Modified Proctor test, AASHTO soil classification, and CBR test were performed on controlled and stabilized soil samples. The aim of this research study was to examine the influence of ground granulated blast-furnace slag (GGBFS) on the index, Compaction and mechanical strength parameters of natural Khairpur Mirs’ soil. Finally, based on laboratorial tests, it was observed that stabilization of soil by GGBFS made favourable changes on the index, compaction and strength parameters of District Khairpur Mirs’ soil.

This paper comprises of the experimental study of double skinned (DSCFT) Composite hollow columns using Geopolymer concrete. The diameter-thickness (D/t) ratio and the hollowness ratio were consideredas main parameters in designing the specimens. The Geopolymer Concrete used in this project is the most promising technique. It is composed of fly-ash, fine aggregate, coarse aggregate and alkaline solution. By using large volume of ordinary Portland cement (OPC) concrete, the production of cement increases 3% annually. The production of one ton of cement directly liberates about 1 ton of CO2 and indirectly liberates 0.4 ton of CO2 to atmosphere. Among the greenhouse gases, CO2 contributes about 67% of global warming. In this respect fly ash based geopolymer mortar is highly considerable. But most of the previous works on fly ash-based geopolymers concrete reveals that hardening is due to heat curing, which is considered as a limitation for cast in situ applications at low ambient temperatures. In order to overcome this situation, replacing the Ground blast furnace slag with fly ash for various proportions to achieve geopolymer concrete suitable for curing without elevated heat. The Scope of this project is to find optimization level of Ground Granulated blast furnace slag in geopolymer concrete for curing in ambient condition and to analyze the compressive Strength of optimized GGBS based Geopolymer Concrete filled double skinned steel tube by varying the size of the steel tubes.
