“…Also the weak bond between the new ITZ and the old ITZ as shown in SEM images presented in Figs. 4 and 5 might be responsible for the reductions in compressive strength, as it directly depends on the nature of RCA and this mutual bonding influences the mechanical properties [11,26,[53][54][55][56][57][58][59][60]. The achieved pattern of compressive strength proves that lower percentage replacement (CF-RCA25) of NA with RCA does not impart harmful effect and a satisfactory performance in case of intermediate (CF-RCA50) mix has also been observed.…”

“…The unique characteristic of SCC is a rapid rate of concrete placement. Compaction of this concrete is accomplished in all the parts of the form, including the hardly accessible parts, with no additional external force, except the gravity that is a result of the concrete self-weight [2,3]. Such properties can be achieved by the addition of chemical additives to the concrete, such as superplastificators, most frequently combined with the new type of additives for modification of viscosity, and/or through the application of a certain amount of fine mineral additive powder [4].…”

This paper addresses durability and shrinkage performance of the self-compacting concretes (SCCs) in which natural coarse aggregate (NCA) and/or natural fine aggregate (NFA) were replaced by recycled coarse aggregate (RCA) and/or recycled fine aggregate (RFA), respectively. A total of 16 SCCs were produced and classified into four series, each of which included four mixes designed with two water to binder (w/b) ratios of 0.3 and 0.43 and two silica fume replacement levels of 0 and 10%. Durability properties of SCCs were tested for rapid chloride penetration, water sorptivity, gas permeability, and water permeability at 56 days. Also, drying shrinkage accompanied by the water loss and restrained shrinkage of SCCs were monitored over 56 days of drying period. Test results revealed that incorporating recycled coarse and/or fine aggregates aggravated the durability properties of SCCs tested in this study. The drying shrinkage and restrained shrinkage cracking of recycled aggregate (RA) concretes had significantly poorer performance than natural aggregate (NA) concretes. The time of cracking greatly prolonged as the RAs were used along with the increase in water/binder ratio.

“…Some of potential waste materials either from construction industry or from by product industry and there are commonly available in every country in all over the world. Those waste materials are abundant and causes environmental pollution such as roof tile [22], recycle aggregate [24,33,36], waste marble [11,17,36,42], RHA [25,35,38,41] and recycled plastic particle [40]. The performances of utilizing those materials are subjective to the purposed of the study and should be explored and established from time to time for the benefit of all parties.…”

Abstract. Self-compacting concrete (SCC) was first developed in late 80's in Japan. SCC is well known for its self-consolidation and able to occupy spaces in the formwork without vibration and become new interesting topic in Construction and Building Materials Research. The aim of this review is to summaries the previous research work related to utilization of waste minimization in SCC from 2009 to 2015 through available literature. It is important to expose new researchers on concept and fundamental theory developed by previous researchers as a reference and guidance in their research. There were a lot of opportunity to be explored in developing SCC especially in utilizing waste material as replacement materials or additives used and mix design method for rheological improvement in SCC. However, these review only focusing on waste materials that have significant to be taken care to reduce environmental impact such as waste product from construction industry and by product industry. As conclusion, this paper will provide significant idea and useful information to those new to SCC and fellow researchers for future studies in utilizing waste materials in SCC mix design.
