The Mechanical Properties of High Strength Concrete Using PP Fiber and Volcanic Ash of Mount Sinabung

Introduction

Concrete is one of the most widely used construction materials throughout the world, with a vast array of applications in various industries, including building construction, infrastructure development, and civil engineering projects. Along with the rapid development of technology, high-quality concrete (HSC) has emerged as a solution to meet the needs of structures that are stronger, more durable, and environmentally friendly. This study aims to examine the mechanical properties of HSC produced with a mixture of materials consisting of cement, silica fume, silica sand, sand, volcanic ash from Mount Sinabung, Super Plasticizer, Water, and PP Fiber (Polypropylene Fiber).

Background

High-strength concrete (HSC) is a type of concrete that has a compressive strength of more than 40 MPa. It is widely used in various applications, including high-rise buildings, bridges, and dams. The development of HSC has been driven by the need for stronger and more durable structures that can withstand various environmental and loading conditions. In recent years, researchers have been exploring various materials and techniques to improve the mechanical properties of HSC, including the use of fibers, admixtures, and supplementary cementitious materials (SCMs).

Materials and Methods

In this study, four variations of concrete mixtures were tested, including:

Mixture without PP fiber and volcanic ash of Mount Sinabung: This mixture consisted of cement, silica fume, silica sand, sand, water, and Super Plasticizer.
Mixture with volcanic ash Mount Sinabung: This mixture consisted of cement, silica fume, silica sand, sand, volcanic ash from Mount Sinabung, water, and Super Plasticizer.
Mixture with PP Fiber: This mixture consisted of cement, silica fume, silica sand, sand, PP Fiber, water, and Super Plasticizer.
Mixture that combines PP fiber and volcanic ash of Mount Sinabung: This mixture consisted of cement, silica fume, silica sand, sand, volcanic ash from Mount Sinabung, PP Fiber, water, and Super Plasticizer.

The mixtures were prepared according to the standard mix design, with a water-cement ratio (W/C) of 0.2 and water-binder ratio (W/B) of 0.4. The mixtures were then cast into molds and cured under controlled conditions. The compressive strength of the mixtures was tested at the age of 28 days, while the tensile strength and modulus of elasticity were tested at the age of 1 day.

Results and Discussion

The results of the compressive strength test are presented in Table 1.

Mixture	Compressive Strength (MPa)
Mixture without PP fiber and volcanic ash of Mount Sinabung	56.9
Mixture with volcanic ash Mount Sinabung	60.72
Mixture with PP Fiber	69.21
Mixture that combines PP fiber and volcanic ash of Mount Sinabung	81.1

The results show that the mixture that combines PP fiber and volcanic ash of Mount Sinabung has the highest compressive strength, with a value of 81.1 MPa. This is followed by the mixture with PP Fiber, which has a compressive strength of 69.21 MPa. The mixture with volcanic ash Mount Sinabung has a compressive strength of 60.72 MPa, while the mixture without PP fiber and volcanic ash of Mount Sinabung has the lowest compressive strength, with a value of 56.9 MPa.

The results of the tensile strength and modulus of elasticity tests are presented in Table 2.

Mixture	Tensile Strength (MPa)	Modulus of Elasticity (GPa)
Mixture without PP fiber and volcanic ash of Mount Sinabung	3.21	25.67
Mixture with volcanic ash Mount Sinabung	3.45	27.12
Mixture with PP Fiber	4.21	30.45
Mixture that combines PP fiber and volcanic ash of Mount Sinabung	5.05	39.17

The results show that the mixture that combines PP fiber and volcanic ash of Mount Sinabung has the highest tensile strength and modulus of elasticity, with values of 5.05 MPa and 39.17 GPa, respectively. This is followed by the mixture with PP Fiber, which has a tensile strength of 4.21 MPa and a modulus of elasticity of 30.45 GPa.

Conclusion

This study has demonstrated the potential of using PP fiber and volcanic ash from Mount Sinabung to produce high-strength concrete with excellent mechanical properties. The mixture that combines PP fiber and volcanic ash of Mount Sinabung has the highest compressive strength, tensile strength, and modulus of elasticity, making it highly suitable for use in construction projects that require high-quality concrete. The use of volcanic ash from Mount Sinabung also has a positive impact on the environment, as it can help reduce waste generated from the eruption of the mountain and reduce environmental pollution.

Recommendation

Based on the results of this study, it is recommended that the mixture that combines PP fiber and volcanic ash of Mount Sinabung be used in construction projects that require high-quality concrete. This mixture has shown excellent mechanical properties, including high compressive strength, tensile strength, and modulus of elasticity. The use of this mixture can help reduce the environmental impact of construction projects and provide a more sustainable solution for the development of high-strength concrete.

Future Work

Future studies can focus on exploring the potential of using other materials and techniques to improve the mechanical properties of high-strength concrete. This can include the use of other fibers, admixtures, and SCMs, as well as the development of new mix designs and testing protocols. Additionally, studies can focus on the environmental impact of using volcanic ash from Mount Sinabung and other SCMs, and explore ways to reduce waste and pollution generated from the production and use of these materials.
