Experiments for Making Lightweight Concrete with the Addition of Ash Sinabung and Silica Fume to Concrete Foam for Structural Purposes

Introduction

In recent years, lightweight concrete has gained significant attention in the construction industry due to its numerous benefits, including reduced weight, improved thermal insulation, and enhanced durability. One type of lightweight concrete that has gained popularity is foam concrete, also known as cellular concrete or porous concrete. Foam concrete is a type of concrete that contains air bubbles or pores, which reduce its density and weight compared to traditional concrete. In this study, we aim to investigate the effects of adding ash from Mount Sinabung and silica fume to foam concrete on its compressive strength and weight.

The Importance of Lightweight Concrete

Lightweight concrete is a type of concrete that has a lower density than traditional concrete. This is achieved by incorporating air bubbles or pores into the concrete mixture, which reduces its weight and improves its thermal insulation properties. Lightweight concrete is particularly useful in construction projects where weight is a concern, such as in high-rise buildings, bridges, and other infrastructure projects. In addition, lightweight concrete can also reduce the structural load received by the building, which can lead to cost savings and improved safety.

The Role of Ash from Mount Sinabung and Silica Fume

Ash from Mount Sinabung is a type of volcanic ash that is rich in silica and alumina. Silica fume, on the other hand, is a by-product of the production of silicon metal and ferrosilicon alloys. Both of these materials have been shown to have beneficial effects on the properties of concrete, including improved compressive strength, durability, and resistance to chemical attacks. In this study, we aim to investigate the effects of adding ash from Mount Sinabung and silica fume to foam concrete on its compressive strength and weight.

Experimental Methodology

In this study, we prepared foam concrete mixtures with varying levels of foam content (10% and 20%) and added ash from Mount Sinabung and silica fume to the mixtures. The mixtures were then tested for their compressive strength and weight. The results showed that the addition of ash from Mount Sinabung and silica fume to foam concrete increased its compressive strength and reduced its weight.

Results and Discussion

The results of this study showed that the addition of ash from Mount Sinabung and silica fume to foam concrete increased its compressive strength and reduced its weight. At 10% foam content, the addition of ash from Mount Sinabung increased the compressive strength of the concrete by 12%, while the addition of silica fume increased the compressive strength by 7.1%. At 20% foam content, the addition of ash from Mount Sinabung increased the compressive strength of the concrete by 15.8%, while the addition of silica fume increased the compressive strength by 15.4%. In addition, the results showed that the addition of ash from Mount Sinabung and silica fume to foam concrete reduced its weight by 1.9% and 0.4%, respectively, at 10% foam content, and by 0.9% and 0.45%, respectively, at 20% foam content.

Benefits and Implications of Research

This study provides an important insight into the use of alternative materials in making lightweight concrete. By utilizing ash from Mount Sinabung, which usually becomes waste, we can reduce the negative impact on the environment. In addition, silica fume as added material can improve concrete performance without significantly adding weight. The use of foam concrete also has practical implications in the world of construction, including reduced weight, improved thermal insulation, and enhanced durability. This is particularly useful in construction projects where weight is a concern, such as in high-rise buildings, bridges, and other infrastructure projects.

Conclusion

In conclusion, this study demonstrates the potential of using ash from Mount Sinabung and silica fume to improve the properties of foam concrete. The results of this study show that the addition of ash from Mount Sinabung and silica fume to foam concrete increased its compressive strength and reduced its weight. This study provides an important insight into the use of alternative materials in making lightweight concrete and has practical implications in the world of construction. Further research is needed to investigate the effects of varying levels of foam content and the proportion of mixture on the properties of foam concrete.
