Properties of recycled concrete aggregate and their influence in new concrete production
TL;DR: In this paper, the authors present a review of the potential and challenge of using recycled concrete aggregate (RCA) as the substitute for natural aggregate (NA) in concrete mixtures.
Journal ArticleDOI
Green concrete: Prospects and challenges
TL;DR: The increasing demand for green concrete has been spurred by demand for high quality concrete products, desire of nations to reduce green-house gas emission, need for conservation of natural resources and limited landfill spaces as mentioned in this paper.
Journal ArticleDOI
Effect of incorporation of high volume of recycled concrete aggregates and fly ash on the strength and global warming potential of concrete
TL;DR: In this article, the effects of using supplementary cementing materials and recycled concrete aggregates (RCA) in concrete, with emphasis on the ability of using high volumes of fly ash (FA) and RCA to reduce the environmental impacts of the concrete's production process without jeopardizing most of its long-term durability characteristics.
Journal ArticleDOI
Water absorption and electrical resistivity of concrete with recycled concrete aggregates and fly ash
TL;DR: A literature review and experimental results on the effect of high incorporation levels of fly ash (FA) and recycled concrete aggregates (RCA), individually and jointly, on the pore system of concrete that remarkably influences its durability are presented in this article.

Self-Compacting Concrete
Hajime Okamura,Masahiro Ouchi +1 more
TL;DR: Ozawa and Maekawa as mentioned in this paper developed a self-compacting concrete, which can be compacted into every corner of a formwork, purely by means of its own weight and with out the need for vibrating compaction.

Influence of nano-SiO2 addition on properties of hardened cement paste as compared with silica fume
TL;DR: In this paper, the influence of nano-SiO 2 (NS) addition on properties of hardened cement paste (hcp) as compared with silica fume (SF) has been studied through measurement of compressive and bond strengths of hcp, and by XRD and SEM analysis.
Journal ArticleDOI
Characteristics of cement mortar with nano-SiO2 particles
TL;DR: In this paper, the properties of cement mortars with nano-SiO 2 were experimentally studied, and the results showed that the compressive strength of mortars containing nano SiO 2 particles was significantly higher than those of those containing silica fume at 7 and 28 days.
