Abstract

The study has conducted to determine the workability and compressive strength of the self –compacting concrete. The sand has replaced with quarry dust with the proportion of 10, 20, 30 and 40% and super plasticizer was added 0.9%. The experiments were carried out at the Infrastructure University Kuala Lumpur (IUKL) concrete laboratory. Slump flow, J- Ring tests were carried out to determine the workability of self-compacting concrete and compressive strength test was conducted on 7 days and 28th days of curing period. A finding of the study shows that workability and compressive strength has increased by addition of quarry dust. It is concluded that addition of quarry dust up to 30% improve the workability of the self-compacting concrete and further addition of quarry dust decrease the workability. Additionally, compressive strength of the quarry dust modified self-compacting concrete shows the trend of higher compressive strength up to 30% addition of quarry dust with sand replacement and further addition decrease the compressive strength.

Highlights

  • Concrete/cement based product is the most significant composite material in all mankind history

  • Fine aggregate is replaced with quarry dust with the proportion of 10, 20, 30 and 40%.Slump test, J-Ring test and compressive strength experimental tests followed British (BS) and Malaysian JKR (Public Works Department) standards were conducted at Infrastructure University Kuala Lumpur Malaysia (IUKL) to achieve the objective of the study

  • This study concluded that replacement of sand/fine aggregate with quarry dust proportion ratio of 10, 20, 30 and 40% slightly improve the compressive strength and workability of the self-compacting concrete (SCC)

Summary

Introduction

Concrete/cement based product is the most significant composite material in all mankind history. Concrete most commonly use in the building infrastructure from decades and expected to continuously use in the future due to the significance such as abundantly availability across the globe, reasonable cost, easy transportation, placement, compaction, high sustainability, durability, high compressive strength and has ability to use in all kind of environment [1,2]. The concrete durability and compaction related problem was addressed by Okamura in 1986 [3] and [4] in the Tokyo University by developing self-compacting concrete (SCC) called Self-consolidating concrete. SCC has increased more extensive application such as saves labour and compaction noise produced by vibration [6]. The main aim of self-compacting concrete development is to produce compaction free concrete more durable and sustainable concrete that can mold in any shape. The consolidation of ordinary concrete is not easy in the complex structure so it was necessary to develop concrete withstand
