Abstract
Self-compacting concrete is identified as “highly flow able” and stable concrete that can spread readily into place and fill the formwork without any vibration and without undergoing any significant segregation. The design of concrete mix is not a simple task on account of widely varying properties of the constituent materials and many factors affect its target value. The mix design problem is a multi-characteristic optimization problem. However, in the present work, the problem is considered to the single characteristic optimization problem and the characteristic to be optimized strength of concrete. In the present paper, Okamora technique has been applied to obtain optimum of SCC mix design to get the mechanical and structural strength of concrete and cement is replaced by GGBS and fine aggregate is replaced by Robo sand and the experimentation work includes the fresh properties tests on SCC to know the characteristic behaviour and the hardened properties of SCC is determined to know the compression strength, split tensile strength,
flexural strength of beams and durability properties.

5. CONCLUSION
The subsequent conclusions be able to drawn from the experimental investigations
carried out on the behaviour of concretes with GGBS and ROBO sand like partial
replacements for cement and sand.
It is decided that there's an develop within the compressive strength used for
different concrete mixes completed with GGBS and ROBO sand substitute
mixes. The increase is when you consider that of excessive reactivity of
GGBS.
Compressive strength increases with increase of percent of Robo sand and
GGBS upto certain limit.
In order to increase the strength cement is replaced by combination of
GGBS.
According to mix the combine gradation of 45% RS and 55% NS meets the
grading limits of IS: 383, But it has been found that on adding more percent
of Robo Sand i.e 50% RS and 50% NS also for the mix RS 75% and NS 25%
in concrete gives maximum compressive strength.
Good compressive strength is obtained when 40% GGBS is replaced with
cement and natural sand is replaced by 50% and 75% Robo sand.
The maximum 56 days split tensile strength was obtained with 40% GGBS
replaced with cement.
The maximum 56 days flexural strength was obtained at mix (50% RS and
50% NS) and mix (75% RS and 25% NS) along with cement replacement
with GGBS 40%.
Durability test implemented in the investigation by way of acid attack test
with 10% sulphuric acid revealed that 40%GGBS replaced with cement,
Robo sand replaced with50% and 75% of natural sand in concrete is more
durable in terms of durability factors than control mix.
It is observed that mixture of GGBS with Robo Sand concrete will be durable
as compared to control concrete. The other forms of fillers, viz., fly ash, stone powder, and floor glass (as
advocated by way of EFNARC) could also be tried in extraordinary mixtures
and the property of the mixes could also be investigated 6. REFERENCES [1] H.Okamora And M.Ouchi Self-compacting concrete progress, present use and future.
