Abstract:
This research aims to investigate the “Potential of Rice Husk Ash as Cement Alternative in Constructing Bricks: Utilization for ‘Gulayan sa Paaralan’ Program”. The success of this study provides cheaper option of construction materials. The pandemic experience of the Philippines, economic deterioration became a challenge. Prices of prime commodities continuously increases, including the construction industry. Nowadays, there are various cement alternative being utilized inside and outside of the country. Some part here in the Philippines use fly ash as a cement alternative. But fly ash is not readily available in Laguna. That is why the researchers look for an alternative that is readily available, inexpensive and do not harm the environment. In this study, the researchers examine the potential of rice husk ash and they constructed bricks in which they plan to use for the beautification of school’s garden.
In accordance with the governing specification of American Standard of State Highway and Transportation Officials (AASHTO) and American Society for Testing and Materials (ASTM), the researchers conducted a standardized laboratory test.
After series of test, researchers concluded that rice husk ash is not a significant alternative to cement as it reduce the strength and durability of the brick made out of it. However, since the chemical composition, fineness test, and water absorption test of rice husk ash and rice husk ash bricks passed the requirements of American Society for Testing and Materials, the researchers inferred that rice husk ash could still be used as additive in creating a decorative bricks.
