FOR OBJECTIVES OF THE STUDY:
General objectives:
The general objective of the research is to comprehensively examine the
impact of coconut husk fiber and corn-cob ash on the mechanical
properties of concrete. This involves conducting an experiment to gather
and analyze data. The aim is to provide a thorough understanding of how
incorporating coconut husk fiber and corn-cob ash into concrete hollow
blocks affects its mechanical properties, such as compressive strength,
flexural strength, and workability.
The general objective of the research is to examine the impact of concrete hollow
blocks reinforced with coconut husk fibers and mixed with corn ash on compressive

Specific objectives:
To determine the effects of incorporating coconut husk fiber and corn-cob ash
on the compressive strength, tensile strength, and flexural strength of
concrete hollow blocks.
To identify the optimal size of coconut husk fiber that can be used as an
additive in concrete mixtures to improve mechanical properties.
To establish the optimal percentage of coconut husk fiber to be used as an
additive for aggregates in concrete mixtures to achieve enhanced strength
characteristics.
To determine the optimal percentage of corn-cob ash to be used as a partial
replacement in concrete mixtures to maximize compressive strength and
durability.
To evaluate the most effective method of incorporating coconut husk fiber
and corn-cob ash into concrete mixtures for improving both mechanical and
durability properties.
To assess the consistency of material performance and quality in concrete
mixtures when coconut husk fiber and corn-cob ash are used as additives or
partial replacements at varying proportions.
The research focuses on achieving the objectives by investigating the effects of
reinforcing CHF with CA ash to concrete hollow blocks by analyzing its mechanical
properties such as compressive strength, tensile strength, and flexural strength. The
purpose of this study is to determine the ideal percentage of CHF with CA ash that
improves the concrete hollow blocks performance through extensive trials. This
study will determine if reinforcing concrete hollow block with CHF with CA ash is
more effective than reinforcing concrete hollow block with CHF.
