The main purpose of the research was to partially replace the
reused substrates with natural preservatives. Five mixtures were
formed with different percentages of the recycled granules (0-
100%) and for constant W/C, and the study of the possibility of
disposal of the ruins of the destroyed buildings through their reuse
in the work of the concrete and the positive effect on the
environment.
The objective of this research is to study the effect of wood ash in
rheological properties of Self – compacting mortar (SCM). By
implemented some mixtures with different percentage from wood
ash with two kinds of cement and three kinds of super plasticizer
and study the effect in slump flow and yield stress to this
mixtures.
Featuring a self-compacting concrete (SCC) high capacity to fill the mold and
passing ability through barriers under the influence of self-weight without vibration,
thereby reducing the required labour and reduces the noise associated with vibratio
n.
Modern applications focused on improving the specifications of high performance,
resistance and speed of construction. The research presents an experimental study for an
(SCC) mix produced from local materials, including the necessary tests on the proposed
concrete mix, which approved in the global codes. These experiments determine the basic
characteristics of (SCC) in fresh case were also identified pressure resistance of (SCC) and
determine the value of the modulus of elasticity (E) and the behavior curvatures. All mixes
have been achieved global standards and conditions, and the required experiments were
done in the laboratory of civil engineering faculty at Tishreen University.
