NANO MODIFIED HIGH VOLUME FLYASH SELF COMPACTING CONCRETE

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...

Properties of Self-Compacting Concrete with Machine-Made Sand and High-Volume Mineral Admixtures

Based on appropriate assessment methods and indexes of self-compacting concrete proposed, properties of concrete made with river-sand and machine-made sand was firstly compared in different mix proportions. The techniques such as basic parameters optimization of mix proportion, admixture composition, large-volume mineral admixtures addition for preparing machine-made sand self-compacting concre...

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...
