EFFECT OF ADMIXTURES ON SHRINKAGE PROPERTIES IN SELF COMPACTING CONCRETE

Effect of Mineral Admixture on Properties of Self Compacting Concrete

In this study, the benefits of limestone powder (LP) and marble powder (MP) as partial replacement of Portland cement are established. Furthermore, LP and MP are used directly without attempting any additional processing in the production of selfcompacting concrete (SCC). The water to binder ratio is maintained at 0.33 for all mixtures. The examined properties include workability, compressive s...

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...

Self-compacting Concrete (scc)

An Effect on Oyster Shell Powder’s Mechanical Properties in Self Compacting Concrete

Self – compacting concrete (SCC) is a high – performance concrete that can flow under its own weight to completely fill the form work and self-consolidate without any mechanical vibration. Such concrete an accelerate the placement, reduce the labor requirements needed for consolidation, finishing and eliminate environmental pollution. Oyster shell were collected from river and sea & it produced...
