EXPERIMENTAL COMPRESSIVE STRENGTH AND MODULUS OF ELASTICITY OF MASONRY
Abstract: Compressive strength
and Modulus of elasticity of masonry are significant parameters when
considering structural masonry
design. This paper presents
those masonry properties which
were determined experimentally. Three
types specimens made of clay
brick masonry and concrete block masonry were built. They were tested in compression
until failure and
conducted in accordance
with the BS
EN 1052-1:1999. Properties
of structural units
and the mortar
were also determined.
Results show that the mean compressive strength of the mortar, clay
brick units and concrete block
units are 4.2
N/mm2, 63.0 N/mm2
and 12.8 N/mm2 respectively. The characteristic compressive strength of
masonry made of clay brick is 11.2 N/mm2 and that made
of concrete block
is 7.2 N/mm2.
The failure of
the masonry tested
in compression was due
to development of
tensile cracks parallel
to the axis
of the loading. Modulus
of elasticity of
masonry was close
to 1000 fk
which is a
formula given in Eurocode 6.
