Basic Properties of Self-compacting Concrete Using Seawater and Sea Sand

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...

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...

Estimation of mechanical and durability properties of self-compacting concrete with fibers using ultrasonic pulse velocity

In this research, the performance of ultrasonic pulse velocity (UPV) in concrete is examined as a nondestructive experiment in order to estimate mechanical (compressive and tensile strength) and durability (water absorption) properties of fiber-reinforced self-compacted concrete For this purpose 11 mixture designs containing 3 types of fibers (steel: 0.1, 0.2, 0.3 and 0.4 percent by volume, Pol...

Self-compacting Concrete (scc)

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...
