Abstract

Self-Compacting Concrete (SCC) is a unique kind of concrete that tends to consolidate in terms of its weight. In this study, the prime target is to investigate the durability properties of SCC developed using eco-friendly economical waste binding materials as partial replacement to costly cement. This circular economy concept will not only help in the development of green concrete but will also help to improve the climatic condition by reducing the use and production of cement. An economical design methodology has been applied to produce environmentally friendly construction material. This research focuses on the application of Alum Sludge (AS) and Brick Dust (BD) in Self-Compacting Concrete (SCC). Both materials are waste materials containing binding properties. Performance of SCC developed using these two materials was tested considering mechanical properties of concrete using the destructive testing technique. Results showed that BD and AS can be utilized for up to 12% and 9% of replacement of cement, respectively, to achieve equal or higher compressive, tensile, and flexural strength. The application of BD and AS has demonstrated a subsequent improvement of SCC’s mechanical properties, i.e., compressive, tensile, and flexural strength. This study will help the production of composite green materials with the help of eco-friendly and economical waste materials for sustainable infrastructure development.

Highlights

Self-Compacting Concrete (SCC) has a different behavior to that of normal concrete used around the globe in the construction industry
The reason is that both materials induced the binding properties of self-compacted concrete, which leads to improved strength properties
In the current research conducted upon the Alum Sludge and Brick Dust that were incorporated in SCC by an effective partial replacement of the ordinary Portland cement, we came can develop the following comprehensive conclusions based on the results obtained after deep evaluation by testing

Summary

Introduction

Self-Compacting Concrete (SCC) has a different behavior to that of normal concrete used around the globe in the construction industry. Bricks are the major and most important type of utilized building material used around the globe and are a main part of this construction industry With such large-scale production, there becomes a generated waste outcome in the form of brick dust or surkhi. The raw constituents are made after manufacturers are supplied with the appropriate raw ingredients and residual by-products of different sources (i.e., GGBFS, FA, and SF) to replace conventional cement (OPC) and reduce waste dumping. This is addressed by construction techniques and the building’s service life. The structure should be renovated and maintained as necessary to enhance its lifespan
