Pozzolan (poz) effects on self-compacting concrete fresh properties

Abstract

The issue of concrete durability has become a matter of global significance, as the presence of inadequate quality and strength has led to structural failures in various countries, including Algeria. Academic researchers are currently engaged in efforts to enhance the overall quality of conventional concrete and develop alternative concrete products. Self-compacting concrete (SCC), an innovative development in the construction sector, was first introduced by Japanese researchers during the 1980s. The self-compacting concrete (SCC) possesses distinctive characteristics, including its capacity to surmount hindrances and compact itself, which can solely be attained by means of methodical optimization of its composition and components. This research examines the attributes of selfconsolidating concrete (SCC) through the incorporation of pozzolan as a means to enhance the fines content, reduce cement consumption, and enhance workability. The findings indicate that self-compacting concrete (SCC) demonstrates favorable performance under ambient conditions, taking into account the impact of pozzolan (poz).

The Utilization of Recycled Concrete Aggregates in Fiber-Reinforced SelfCompacting Concrete

“…Because it ignores the crucial components of admixtures and additions, the Dreux-Gorisse method is deemed inappropriate and impracticable for selfcompacting concrete (SCC) [13][14][15][16][17][18][19]. The majority of self-consolidating concrete (SCC) formulas are currently developed primarily through empirical methods [20][21][22][23][24].…”

Influence of recycled concrete gravel and sand in self-compacting concrete (SCC)

“…By rigorously following established guidelines and incorporating recommendations from specialized literature, we successfully achieved self-compactability in our concrete mix designs. To determine the proportions of components needed for 1 cubic meter of concrete, it is necessary to have comparable data for the parameters mentioned in references [21], [22], [23], [24].…”

The role of fibers and mineral admixtures in self-compacting concrete

“…By incorporating superplasticizers, it is possible to enhance the fluidity of the paste by inducing a minor reduction in its viscosity. It is conceivable to identify the optimal combination of water-to-powder ratio (W/P) and superplasticizers for concrete with a fixed aggregate content, enabling it to achieve self-mixing properties [22].…”
