Abstract Recycle aggregate is one of the good options to use in concrete as coarse aggregate which results environmental benefits as well as sustainable development. However, recycle aggregate cause reduction in concrete performance. One the other hand, the removal of industrial waste would be considerably decreased if it could be incorporated in cement concrete production. One of these possibilities is the substitution of the cement by slag, which enhance concrete poor properties of recycle aggregate concrete as well as provides to the decrease of cement consumption, reducing carbon dioxide productions, while resolving a waste management challenge. Furthermore, steel fiber was also added to hance the tensile capacity of recycle aggregate concrete. The main goal of this study is to investigate the characteristics of concrete using Ground granulated blast-furnace slag (GGBS) as binding material on recycle aggregate fibers reinforce concrete (RAFRC). Mechanical performance was assessed through compressive strength and split tensile strength, while durability aspects was study through water absorption, acid resistance and dry shrinkage. The results detected from the different experiments depict that replacement of Ground granulated blast-furnace slag (GGBS) enhance mechanical performance as well as durability aspects of the recycle aggregate fibers reinforce concrete (RAFRC).

To improve the application of low-quality aggregates in structural concrete, this study investigated the effect of multi-purpose mineral admixtures, such as fly ash and ground granulated blast-furnace slag, on the performance of concrete. Accordingly, the primary performance of low-quality recycled aggregate concrete could be improved by varying the replacement ratio of the recycled aggregate and using appropriate mineral admixtures such as fly ash and ground granulated blast-furnace slag. The results show the potential for the use of low-quality aggregate in structural concrete.

Abstract Ground granulated blast furnace slag (GGBFS) is one of green construction materials that held benefits in producing sustainable and high-quality concrete. GGBFS is commonly used as supplementary cementitious materials in blended cement to reduce the need for Portland cement in mortar or concrete production. An overview of the utilization of GGBFS as partial cement replacement with regards to mortar and concrete properties is presented in this paper. The fresh properties of GGBFS mixes addressed include workability and setting time. While compressive strength, porosity, shrinkage, and resistance to sulfate attack are the reviewed hardened properties. Overall, various studies showed that incorporating GGBFS in mortar/concrete mixes significantly improves mortar/concrete properties depending on the GGBFS replacement ratios. It is anticipated that this review will provide valuable information for a better understanding of the fresh and hardened properties of GGBFS-blended mortar and concrete. Moreover, as there is a growing interest in optimal utilization of GGBFS in Indonesia’s cement and construction industry, this review paper intended to raising awareness of GGBBFS utility regarding its benefit for sustainable construction.

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.
