EFFECT OF FLY ASH AND BRICK DUST AS A PARTIAL REPLACEMENT OF FINE AGGREGATES IN SELF COMPACTING CONCRETE

Self-compacting concrete (SCC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. Complex shape of concrete structures and densely arranged bars make it more difficult to use a vibrator. Vibratory compaction is noisy and deleterious to the health of construction workers, as well as an annoyance to people in the neighbourhood. In remote areas it is difficult to find skilled workers to carry out the compacting work at construction sites. This paper presents the progress of the research on different harden properties of Self Compacting Concrete using the Ordinary Portland Cement “Ultratek” made and low-calcium fly ash from Birala Glass, Kosamba, Gujarat, as binder materials in making the concrete mixes along with other ingredients locally available in Gujarat. the hardened properties like compressive strength, split tensile strength, flexural strength and impact strength are found in experimental work and are compared with M25 grade of concrete. In the present context the Self Compacting Concrete can be proved as boon to construction industry.
