Abstract
The durability of cementitious materials is
significantly influenced by their water absorption properties, which affect
their longevity and resistance to environmental degradation. This study
investigates the potential of using highly active metakaolin and recycled glass
waste as supplementary cementitious materials to reduce water absorption in
concrete mixtures. The primary objective is to enhance the impermeability and
durability of cement-based composites by incorporating these pozzolanic
additives. Experimental methods involved preparing various concrete samples
with different proportions of metakaolin and glass waste, followed by
standardized water absorption tests, compressive strength measurements, and
microstructural analysis using scanning electron microscopy (SEM). Results
demonstrated that incorporating highly active metakaolin significantly
decreased water absorption rates by refining the pore structure and enhancing
the cement matrix’s density. Additionally, glass waste contributed to improved
particle packing and acted as a partial cement replacement, further reducing
permeability. The combined use of metakaolin and glass waste led to an optimal
reduction in water absorption without compromising mechanical performance.
These findings suggest that utilizing sustainable and industrial by-products in
cementitious materials can improve durability while promoting environmental
benefits through waste recycling. This research supports the development of
more resilient and eco-friendly construction materials.
