Batako Physical Characterization With The Use Of Rice Straw Ash
Batako Physical Characterization with the Use of Rice Straw Ash
Introduction
The increasing demand for sustainable and environmentally friendly building materials has led to the exploration of alternative materials and waste utilization methods. One such method is the use of rice straw ash as a mixture in the manufacture of bricks. Rice straw ash is a by-product of rice straw combustion, which is typically discarded as waste. However, it has been found to have pozzolanic properties, making it a potential additive in cement-based materials. This study aims to investigate the physical characteristics of bricks made with rice straw ash as a mixture in sand with varying compositions.
Background
The use of waste materials in construction has gained significant attention in recent years due to its potential to reduce waste disposal costs and promote sustainable development. Rice straw ash, in particular, has been found to have pozzolanic properties, which can react with cement to form strong silicate compounds. This reaction can improve the mechanical properties of cement-based materials, such as compressive strength and durability. However, the use of rice straw ash as a mixture in brick manufacture has not been extensively studied, and its effects on the physical characteristics of bricks are not well understood.
Methodology
This study was conducted by mixing rice straw ash with sand in varying proportions (0%, 10%, 20%, 30%, 40%, and 50%) to produce bricks. The bricks were then formed using a pressure of 150 kgf and allowed to harden for 28 days. The physical characteristics of the bricks were tested, including compressive strength, impact strength, hardness, water absorption, and density.
Results
The results of this study showed that the best composition was the mixing of rice straw ash at 10% of the mass of sand. In this composition, the brick had optimal characteristics, including:
*** Compressive Strength: 9.06 MPa *** Impact Strength: 1.47 x 10^4 J/m^2 *** Hardness: 88 Hb *** Water Absorption: 13.32% *** Density: 1.75 g/cm^3
The addition of rice straw ash to the 10% composition was found to increase the compressive strength, impact strength, and hardness of the brick. This is attributed to the pozzolanic properties of rice straw ash, which can react with cement to form strong silicate compounds. Additionally, the use of rice straw ash was found to reduce water absorption and increase brick density.
Discussion
The results of this study demonstrate the potential of rice straw ash as a mixture in the manufacture of bricks. The addition of rice straw ash to the 10% composition was found to improve the physical characteristics of the brick, including compressive strength, impact strength, and hardness. This is attributed to the pozzolanic properties of rice straw ash, which can react with cement to form strong silicate compounds.
The use of rice straw ash as a mixture in brick manufacture also has the potential to reduce waste disposal costs and promote sustainable development. Rice straw ash is a by-product of rice straw combustion, which is typically discarded as waste. By utilizing rice straw ash as a mixture in brick manufacture, the amount of waste generated can be reduced, and the quality of bricks can be improved.
Conclusion
This study demonstrates the potential of rice straw ash as a mixture in the manufacture of bricks. The addition of rice straw ash to the 10% composition was found to improve the physical characteristics of the brick, including compressive strength, impact strength, and hardness. The use of rice straw ash as a mixture in brick manufacture also has the potential to reduce waste disposal costs and promote sustainable development.
Recommendations
Based on the results of this study, the following recommendations are made:
- Further studies should be conducted to investigate the effects of rice straw ash on the mechanical properties of bricks.
- The use of rice straw ash as a mixture in brick manufacture should be explored in more detail, including its effects on the durability and sustainability of bricks.

Limitations
This study has several limitations, including:
- The study was conducted using a limited number of samples, which may not be representative of the population.
- The study only investigated the physical characteristics of bricks made with rice straw ash as a mixture in sand, and did not investigate the effects of rice straw ash on the chemical properties of bricks.
Conclusion
In conclusion, this study demonstrates the potential of rice straw ash as a mixture in the manufacture of bricks. The addition of rice straw ash to the 10% composition was found to improve the physical characteristics of the brick, including compressive strength, impact strength, and hardness. The use of rice straw ash as a mixture in brick manufacture also has the potential to reduce waste disposal costs and promote sustainable development.
