Study of the Effect of Plastic Waste Fibers Incorporation on the Behavior of Self Compacting Concrete
In this context, the self-compacting composites by adding a variable percentage of plastic fibers at 0.5, 1, 1.5% is formulated. Hence, the effect of plastic fibers waste on the rheological and mechanical properties of SCC is assessed. The obtained results in the present study let us to conclude the beneficial effect of such inclusion of plastic fibers on this new confected SCC fiber composition with acceptable rheological, physical and mechanical properties compared to those of a normal SCC concrete.

The Influence of the Nature of Different Sands on the Rheological and Mechanical Behavior of SelfCompacting Concrètes
Abstract
Self-Compacting concrete (SCC) represents a new step forward for concrete construction as it offers many advantages from
an economic, technical and social point of view. They are very fluid concretes, which are placed without vibration, under the
simple effect of gravity. Thanks to their formulation, they offer exceptional flowability and filling characteristics of the
formwork while being perfectly resistant to segregation. Homogeneous and stable, they have resistances and durability similar
to those of traditional concretes, of which they differ in their fresh properties. The use of SCC leads to a reduction of noise in
some civil engineering applications works.
This research work is a part of a policy of contributing to the improvement of the properties of self-compacting concretes
prepared from local materials of the M'sila region (200 km East of Algeria). The aim of this study is to obtain a formulation of
the most suitable concrete based on for the different local materials at appropriate proportioning.
Our study focuses on the effect of the following parameters on the physical-mechanical properties of the composite, such as
dynamic segregation, workability and mechanical resistances (compressive and tensile strength). It is therefore necessary to
determine the criteria to be imposed on these parameters, in order to achieve the construction of the SCC characterized by
an acceptable resistance.
The obtained results of mechanical response show significant advantageous behaviors for SCC mixtures compared to reference
concrete. They allowed to distinguish a gain of resistance between 15 and around 50 MPa, this gain is explained by a rehydration
of the cementitious matrix due to the migration of water through the pores SCC mixtures but also to better binding properties
of hydrates formed for the new cement matrix composite.

The effect of the kind of sands and additions on the mechanical behaviour of S.C.C
Aggregates are very important components of ordinary and self-compacted concretes (figure 1). It’s well known that they affect both fresh and hardened concrete properties. Concrete flowability depends on the properties of cement paste, the amount and gradation of aggregates. The lowest the surface area and voids
