The Effect of Using Leaf Ash (0% - 17.5%) as a Partial Substitution Material for Concrete Compressive Strength

Introduction

Concrete, a fundamental construction material, has a significant environmental impact due to the large amount of carbon dioxide (CO2) released during the production process of Portland cement, one of its main components. This has led to a search for environmentally friendly alternatives to reduce the carbon footprint of the construction industry. One potential solution is to utilize organic waste as a substitute for some Portland cement, creating an environmentally friendly concrete concept. Lemongrass leaf ash, a byproduct of lemongrass leaves, has been identified as a promising organic waste material that can increase concrete strength.

Utilizing Organic Waste: Lemongrass Leaf Ash for Environmentally Friendly Concrete

Concrete production is a significant contributor to greenhouse gas emissions, with the cement production process accounting for approximately 8% of global CO2 emissions. The search for sustainable alternatives has led to the exploration of using organic waste as a substitute for Portland cement. Lemongrass leaf ash, a byproduct of lemongrass leaves, has been identified as a potential substitute material due to its high mineral content. Research has been conducted to examine the effect of using lemongrass ash with a variation of 0% to 17.5% as a partial substitution of cement on concrete compressive strength.

The Effect of Lemongrass Ash on Concrete Compressive Strength

The results of the research showed that the addition of lemongrass ash as a concrete composition had a significant effect on its compressive strength. At low levels (0% to 5%), lemongrass ash can increase the compressive strength of concrete. This is caused by the minerals in lemongrass ash, which play a role in increasing the density and cohesiveness of the concrete matrix. However, at higher levels (above 5%), the compressive strength of concrete actually decreased. This is attributed to several factors, including:

Changes in Chemical Properties: Lemongrass leaf ash can change the chemical properties of concrete, causing a decrease in bond strength between particles. Increased Porosity: The addition of lemongrass ash in large amounts can increase the porosity of concrete, thereby reducing its strength. Disagreement of Distribution: The uneven distribution of lemongrass ash in concrete can create a weak point, thereby reducing the overall strength of concrete.

Optimizing Lemongrass Ash Content

The use of lemongrass ash as a partial cement substitution can be an environmentally friendly solution for the construction industry. However, it is necessary to adjust and optimize the lemongrass ash content used so as not to reduce the compressive strength of concrete. Further research on the characteristics and influence of lemongrass ash on concrete mechanical properties is needed to determine the best and optimal application in sustainable construction development.
