Manufacture and Test of the Characteristics of a Small Concrete Material (Concrete Foam) Which is Strengthened

Introduction

The construction industry has been facing numerous challenges in recent years, including the need for sustainable and cost-effective building materials. One of the most significant challenges is the disposal of waste materials, which can have a negative impact on the environment. In this context, the use of waste materials as building materials has gained significant attention in recent years. One such material is the Oil Palm Empty Bunches (TKKS), which has been used as a fertilizer but has now been found to have potential as a lightweight concrete reinforcement.

The Potential of TKKS as a Lightweight Concrete Reinforcement

Indonesia, as one of the world's largest oil palm producers, has a significant amount of TKKS waste that can be utilized as building materials. Recent research has shown that TKKS can be used as a lightweight concrete reinforcement, creating environmentally friendly and cost-effective building materials. This study aims to find optimal methods of making lightweight concrete using TKKS and to identify the composition of materials that produce high-quality lightweight concrete.

Objectives of the Study

The main objectives of this study are to:

  • Find optimal methods of making lightweight concrete using TKKS
  • Identify the composition of materials that produce high-quality lightweight concrete
  • Study the characteristics of the strength of lightweight concrete strengthened by TKKS fiber due to static loads

Methodology

To achieve the objectives of this study, a series of testing of the test specimens that have been made was conducted. One of the tests conducted was the tensile test, which aims to determine the strength of mild concrete tensiles. The test specimens were made using a mixture of cement, sand, water, blowing agent, and TKKS fiber.

Results

The results of the study showed that the ideal ratio between the height of the mold and the volume of lightweight concrete mixture material was 1:0.75. The composition of the lightweight concrete material obtained in this study was 32.5% cement, 32.5% sand, 15.1% water, 17.6% blowing agent, and TKKS fiber 2.3%. This composition produces mild concrete with good tensile strength. The tensile voltage value obtained from the test was 0.18 MPa with a strain of 0.0015415.

Advantages of Lightweight Concrete

The use of TKKS as a concrete amplifier has several advantages, including:

*** Environmentally Friendly: **The use of TKKS as a concrete amplifier reduces waste and supports environmental sustainability. *** Cost-Effective: **TKKS is an easy material and relatively cheap, so that it can reduce the cost of mild concrete production. Strength and Resistance: **Research shows that mild concrete with the addition of TKKS fiber has good strength and resistance, so that it can withstand static loads.

Conclusion

This research opens great opportunities in utilizing TKKS waste to create building materials that are more environmentally friendly and cost-effective. The lightweight concrete has great potential to be applied in various building construction, such as the construction of residences, office buildings, and other infrastructure. The use of TKKS as a concrete amplifier is an important step in realizing a more sustainable construction industry. By utilizing the potential of waste and optimizing natural resources, we can build a better future.

Recommendations

Based on the results of this study, the following recommendations are made:

  • Further research is needed to optimize the composition of lightweight concrete materials.
  • The use of TKKS as a concrete amplifier should be promoted in the construction industry.
  • The government should provide incentives for the use of TKKS as a building material.

Future Research Directions

Future research directions include:

  • Investigating the potential of TKKS as a building material in other applications.
  • Developing new technologies to optimize the production of lightweight concrete.
  • Conducting further research on the properties of lightweight concrete.

Limitations of the Study

The study has several limitations, including:

  • The study was conducted on a small scale, and further research is needed to confirm the results.
  • The study only investigated the tensile strength of lightweight concrete, and further research is needed to investigate other properties.

Conclusion

In conclusion, this study has shown that TKKS can be used as a lightweight concrete reinforcement, creating environmentally friendly and cost-effective building materials. The study has also identified the composition of materials that produce high-quality lightweight concrete and studied the characteristics of the strength of lightweight concrete strengthened by TKKS fiber due to static loads. The results of this study have great potential to be applied in various building construction, and the use of TKKS as a concrete amplifier is an important step in realizing a more sustainable construction industry.
