✦ Synopsis

The aim of this paper is to investigate the influence of paste composition and paste volume on the fresh and hardened properties of Self-Compacting Concrete. Nineteen SCC mixtures were investigated for different paste composition and paste volume. Fresh concrete tests such as slump flow, J ring, and V funnel test were performed; hardened concrete tests were limited to compressive strength. The results revealed that slump flow and J ring flow increased with increase in paste volume. A simple empirical equation was proposed for the determination of the paste volume for the required slump flow of SCC. Compressive strength of the different SCC mixtures ranged between 20 MPa and 70 MPa.

In this work, the effect of fine additives (limestone, silica fume, fly ash, pozzolan, nano-silica fume) on the plastic viscosity of cement paste is being investigated. Towards this direction, twenty-four samples were designed and produced. Those pastes consisted mainly of cement (type CEM I 42.5) a

Numerous investigations have been conducted on self-compacting concrete (SCC) and lightweight aggregate concrete (LWAC), but there are relatively very few studies on self-compacting lightweight concrete (SCLC). This paper deals mainly with the mix proportion design for SCLC and its workability. By c
