SOME LETTER DAYS STRUCTURAL PROPERTIES OF CONCRETE CONTAINING PALM OIL EMPTY BUNCH ASH(POEBA) AS PARTIAL REPLACEMENT OF CEMENT IN CONCRETE

Abstract:

This study investigates the structural properties of concrete incorporating Palm Oil Empty Bunch Ash (POEBA) as a partial replacement for cement. As sustainability becomes a critical consideration in construction materials, agricultural waste by-products are explored for their potential contribution to concrete production. POEBA, a residue from the palm oil industry, is examined for its influence on the compressive strength, flexural strength, and durability characteristics of concrete. The research involves laboratory testing and analysis to assess the mechanical and durability properties of concrete mixes containing varying percentages of POEBA. The results provide valuable insights into the feasibility and effectiveness of utilizing POEBA as a sustainable alternative in concrete, contributing to both environmental conservation and the construction industry’s pursuit of eco-friendly practices.

Chapter One: Introduction

1.1 Background of the Study

Concrete, a fundamental construction material, is undergoing a paradigm shift towards sustainability and eco-friendly practices. The demand for environmentally responsible construction methods has led to an exploration of alternative materials that can reduce the ecological footprint of concrete production. One such potential alternative is Palm Oil Empty Bunch Ash (POEBA), a by-product of the palm oil industry. As a residue from the processing of palm oil empty fruit bunches, POEBA holds promise as a supplementary cementitious material for use in concrete. This research aims to investigate the structural properties of concrete containing POEBA as a partial replacement for cement, contributing to the understanding of sustainable construction practices.

1.2 Statement of the Problem

The conventional production of concrete involves the consumption of large amounts of Portland cement, contributing to environmental concerns such as high carbon emissions and energy consumption. The disposal of agricultural waste, including palm oil empty fruit bunches, further compounds environmental challenges. Addressing these issues requires exploring alternative materials like POEBA to reduce the environmental impact of concrete production while maintaining or improving its structural properties. Understanding the effects of POEBA on concrete performance is essential for its successful integration into construction practices.

1.3 Objectives of the Study

The primary objectives of this research are:

To investigate the influence of Palm Oil Empty Bunch Ash (POEBA) on the compressive strength of concrete.

To assess the flexural strength of concrete when POEBA is used as a partial replacement for cement.

To evaluate the durability characteristics, including resistance to chloride ion penetration and sulfate attack, of concrete incorporating POEBA.

To provide insights into the feasibility and effectiveness of POEBA as a sustainable alternative in concrete production.

1.4 Research Questions

To guide the study, the following research questions are formulated:

How does the inclusion of Palm Oil Empty Bunch Ash (POEBA) affect the compressive strength of concrete?

What is the impact of POEBA on the flexural strength of concrete?

How does the presence of POEBA influence the durability characteristics of concrete, specifically in terms of chloride ion penetration and sulfate attack?

What are the feasibility and effectiveness of utilizing POEBA as a partial replacement for cement in concrete?

1.5 Significance of the Study

This research holds significance in several aspects:

Sustainable Construction: Investigating the use of POEBA contributes to sustainable construction practices by repurposing agricultural waste as a valuable construction material.

Reduced Environmental Impact: Understanding the influence of POEBA on concrete properties provides insights into the potential reduction in the environmental impact of concrete production.

Economic Viability: Exploring the feasibility of POEBA as a cement replacement offers the construction industry an eco-friendly alternative that could also be economically viable.

Technological Advancements: The study contributes to advancements in concrete technology by expanding the knowledge base on the use of alternative materials.

1.6 Scope and Limitations

This study focuses on the structural properties of concrete containing Palm Oil Empty Bunch Ash (POEBA) as a partial replacement for cement. The research includes laboratory experiments to assess compressive strength, flexural strength, and durability characteristics. However, the findings may be influenced by factors such as material characteristics, mix proportions, and curing conditions. The geographical applicability of the results may vary based on regional variations in raw materials.

1.7 Organization of the Thesis

The thesis is organized into several chapters to provide a systematic presentation of the research. Chapter Two will review existing literature on the use of alternative materials in concrete production, with a specific focus on palm oil waste by-products. Chapter Three will detail the methodology employed in this research. Subsequent chapters will present the findings, discuss implications, and conclude the study.
