ABSTRACT
Madula, Claissa May et al. Grelina Osmeña Christian College, April 2024. “TALISAY FIBER,
WASTE GLASS AND FLORAL FOAM AS AN AGGREGATES IN CEMENTITIOUS
MATRIX: AN EXPERIMENTAL ANALYSIS ON CONCRETE HOLLOW BLOCK”,
Adviser: Mr. Elpedio T. Vesera Jr.
The experimental study explored how different combinations of talisay fiber, waste glass,
and floral foam impact the properties of concrete hollow blocks (CHBs). The main aim was to
assess how these materials, when used as aggregates in the cement matrix, could offer valuable
insights for local communities and the environment. Commercial CHBs often lack durability and
tend to break easily, highlighting the need for more robust and eco-friendly alternatives. By
incorporating floral foam for water-absorption, waste glass as a sand substitute, and talisay fiber
for strength enhancement, the study aimed to address these shortcomings.
The experiment consisted of three phases, each involving variations in the length and
weight of talisay fiber, as well as the amount of waste glass and floral foam in the CHB mixture.
Control groups with standard Portland cement, sand, and water were compared with experimental
groups featuring different combinations of the three materials. The results of drop tests and water
absorbency measurements identified treatment 4 as a standout performer. This treatment,
comprising specific proportions of about 36% waste glass, 0.2% talisay fiber, and 0.8% floral foam,
demonstrated superior resistance to water penetration while maintaining water absorbency within
the desired limit of 5% for lightweight CHBs.
