| This study aimed to determine the comparison on the perceived effectiveness and
performance of using hollow blocks from rice husk ash as a building material for house
construction as a substitute to commercially-produced hollow blocks. It is to assess whether there
are significant differences in its functionality in terms of compressive strength, thermal and
moisture resistivity, and durability. At the same time, it also aimed to produce modifications for the
hollow blocks from rice husk ash to further improve its usability. Moreover, the study employed
descriptive-experimental method and used a survey questionnaire as the main data gathering
instrument. In line with this, the study has seventy (70) respondents, twenty (20) are civil
engineers and fifty (50) are house owners living in the Batangas City. For the distribution of the
instrument, stratified random sampling was applied. The researchers were able to analyze and
interpret the data through the use of statistical tools including frequency distribution, ranking,
weighted mean, composite mean, and T-test. Based on the data gathered, the results revealed
that hollow blocks from rice husk ash are sufficient enough to be used as an alternative for
commercial hollow blocks as it is equal to or greater than its counterpart in terms of compressive
strength, thermal and moisture, and durability. Thereby, the findings signified that the null
hypothesis is rejected, and statistically proving that there are significant differences on its
effectiveness on the same criteria listed above. The foregoing results of the study were then used
as the foundation for devising modifications for the hollow blocks from rice husk ash. |
