The ceramic industry often produces calcined clays that result from burning
illite-group clays, which are commonly used in the production of red-clay
A portion of these products (which amounts up to 2%
depending on producer and country) is discarded as scrap, and thus constitutes
The residues of ceramic bricks and floor and roof tiles ground
to a suitable fineness can become active pozzolans.
So, they have the potential to
be used in mortar and concrete.
In this paper, mechanical properties and heat and
water transport parameters of high performance concrete containing fine-ground
ceramics as a partial replacement of Portland cement are studied and compared
with reference high performance concrete.
The experimental results show that
the replacement of Portland cement in the amount of 20% by mass is the most
In comparison with reference high performance concrete the
mechanical properties of concrete where up to 20% of cement is replaced by
fine-ground ceramics are similar or slightly worse, and water transport properties
are still acceptable from the durability point of view.

Many industrial byproducts possessing pozzolanic properties are produced in
large amounts worldwide, and despite the current trends of environmental
protection and sustainable construction, their production volume still greatly
