Fresh and hardened properties of self consolidating concrete
Overall, we might conclude that the fresh self-compacting properties of the concrete have little effect on the in-situ strengths.2.Tensile strength Tensile strength was assessed indirectly by the splitting test on cylinders.Hence, the research efforts are focussed to use this waste advantageously by understanding the performance and durability characteristics of rubberized concrete.The present study is carried out an experimental investigation on fresh and hardened properties of Self Compacting Concrete (SCC) containing waste tyre rubber.The total volume of rubber chips are replaced in coarse aggregate i.e. To obtain fresh properties in SCRC the slump, T500, J-Ring, V-Funnel, L-Box and U-Box tests are conducted whereas for hardened properties the Compressive, Flexural and Split Tensile tests are conducted.The grade of concrete used in the present study is M30, whereas for SCC, the mix design is carried out in trial basis.In its simplest form, concrete is a mixture of paste and aggregates (sand & rock).
Bond strength The strength of the bond between concrete and reinforcement was assessed by pullout tests, using deformed reinforcing steel of two different diameters, embedded in concrete prisms.
It can be also categorized as high performance concrete as the ingredients are the same, but in this type of concrete workability is increased.
It is also called self consolidated concrete or flowing concrete.
The key to achieving a strong, durable concrete rests on the careful proportioning and mixing of the ingredients.
A concrete mixture that does not have enough paste to fill all the voids between the aggregates will be difficult to place and will produce rough, honeycombed surfaces and porous concrete.
