Relation between the Workability and Strength of Self-compacting Concrete

This paper presents the results of an experimental research on the workability and compressive strength of self-compacting concrete. The work focused on concrete mixes having water/binder ratios of 0.35 and 0.45, which contained constant total binder contents of 500 kg/m and 400 kg/m, respectively. The concrete mixes contained four different dosages of a superplasticizer based on carboxylic wit...

Properties of Self-compacting Concrete – an Overview

Self-compacting concrete can be defined as the concrete which requires no vibrations and can flow around obstructions, encloses the reinforcement and fills up the formwork completely under its self weight. Over the last ten years, significant amount of work has been carried out on self-compacting concrete all over the world. In countries like Japan, Sweden, Thailand, UK etc., the knowledge of S...

Ultra High Performance Self Compacting Concrete

Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...
