Thesis (B.S.) -- Cagayan State University, 2025.
This study investigates the potential of utilizing moss in the surface application on concrete hollow blocks (CHBs), with a focus on its effects on mechanical properties, particularly water absorption, moisture content and compressive strength. In response to the increasing demand for environmentally sustainable construction materials, the research examines the performance of CHBs treated with two types of moss-Sheet Moss and Sphagnum Moss. The moss was not incorporated into the concrete mixture but was surface applied to CHBS to assess its influence under tropical environmental conditions, particularly in Tuguegarao City.
Three sets of samples were prepared: untreated CHBS (control), CHBS with surface- applied Sheet Moss, and CHBS with surface-applied Sphagnum Moss. Testing procedures were conducted to evaluate water absorption and compressive strength. The findings revealed that the surface application of moss significantly affected the mechanical performance of CHBS. Notably, Sheet Moss demonstrated superior performance, recording the highest compressive strength and the lowest moisture content and water absorption among the three groups. This can be attributed to its relatively compact and less absorbent structure, which contributed to enhanced strength and reduced permeability. In contrast, CHBS treated with Sphagnum Moss showed the lowest compressive strength and the highest values for moisture content and water absorption, likely due to the moss's spongy and highly porous nature.
These results suggest that while Sphagnum Moss may provide benefits in terms of moisture retention for environmental regulation, Sheet Moss is more suitable for load-bearing applications where structural integrity is critical. The study concludes that surface-applied Sheet Moss holds strong promise for integrating sustainability into masonry construction, especially in hot and humid climates. With further development, including strategies to manage biological growth and moisture behavior, Sheet Moss could become a valuable component in eco-friendly, load bearing CHB applications.
