About hollow dense 7.3N
The 215mm Hollow Dense 7.3N concrete blocks are robust and heavy-duty
building materials designed for structural and load-bearing walls. These hollow blocks are made with
dense aggregate for high strength and durability, with a compressive strength of 7.3 Newtons per
square millimeter. They are suitable for a variety of construction applications that require both
resilience and efficiency in installation due to their hollow centers.
