PROPERTIES OF MICROSTRUCTURE AND MASS TRANSPORT IN SELF-COMPACTING CONCRETE CONTAINING CELLULOSIC VISCOSITY AGENT

Rheological and Mechanical Properties of Light Weight Self-Compacting Concrete Containing Sirjan Iron Mine Waste

Recycling is a logical option for materials that are not suitable for composting. One of these materials is iron mines waste that, according to their compounds, can be used as a substitute part of cement in concrete. For this aim, rheological and mechanical properties and durability of light weight self-compacting concrete (LWSCC) containing Sirjan iron mine waste (SIMW) as partial substitute o...

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...

Self-compacting Concrete (scc)

Stability of Self-Consolidating Concrete Containing Different Viscosity Modifiers

The main objective of this paper is to assess the effect of different viscosity-enhancing admixture (VEA) types and concentrations on deformability and stability of self-consolidating concrete (SCC). Two polysaccharide-based VEAs, one cellulose-based VEA, and a modified-startch VEA are used in this investigation. Regardless of polymer type, results showed that the incorporation of VEA leads to ...

A Comparison of the Microstructure of self compacting concretes containing nano and microsilica

Abstract Self compacting concrete (SCC) is a new construction material in the world. The aim of this research is to construct self compacting concrete with high compressive strength using combination of nano silica and micro silica. For this purpose, nano silica, micro silica, Portland cement type 2, superplasticizer (SP), and gravel and sand have been used. Three different groups of samples wi...
