In today’s “Golden Age of Infrastructure,” there is a growing global demand for natural
resources in the construction industry, posing significant challenges such as environmental
damage and land resource depletion. This study addresses these concerns by focusing on
characterizing the physical and mechanical properties of modular blocks using recycled
concrete as partial aggregate replacement. The primary aim is to contribute to the optimization
of raw materials use, energy conservation, and reduction of construction and demolition waste,
which significantly impacts environmental sustainability. Recycled concrete aggregate (RCA)
was utilized in four concrete mix designs with varying replacement percentages of 0%, 15%,
30%, and 50% to produce a concrete modular block with 400 mm by 250 mm by 150 mm
dimension. Specimens were subjected to physical and mechanical tests, including compressive
strength, on the 7th and 28th days of age. Based on the results of the study, the use of RCA as
a replacement material resulted in decreased density and moisture content, while it also
demonstrated high water absorption. In terms of mechanical properties, the 30% replacement
with RCA exhibited the highest compressive strength among all the mix designs. The
compressive strength is measured at 4.75 MPa and 5.82 MPa at 7 days and 28 days,
respectively. Among the proposed mix designs, the specimens with 30% volume replacement
of RCA achieve the highest quality.
