A. Ready Mixed Concrete Industry in India The Ready mix concrete business in India is in its infancy but it is having a steady growth in the last 2 decades. For example, 70% of cement produced in a developed country like Japan is used by Ready Mix concrete business there. In Europe and USA it is about 60% [1]. Here in India Ready Mix concrete
M40 grade of concrete is used in the study and mix design was carried out according to guidelines 10262 (2009). Approx. 3-5 % of Silica Fume was used as on cement replacement for all the mix and Effect of GGBS was studied by replacing cement by 5 to 20%.

earlier title 'Recommendedguidelines for concrete mix design'. b) The applicability ofthe standard has been specified for ordinary and standard concrete grades only. c) Various requirements have been modified in line with the requirements of IS 456 : 2000 'Plain and reinforced concrete - Code ofpractice (fourth revision)'.
GGBS has also been used before to replace cement to develop a new mix design methodology of self-compacting concrete. The results indicated that GGBS up to a replacement of 20% to 80% can only be used and concretes up to strength of 30 to 100 MPa can only be developed.
In the present study, a simple and rational mix design methodology has been proposed for developing the fly ash and GGBS based geopolymer concrete. The uniqueness of the proposed methodology lies in considering mainly the specific gravity of raw materials, in addition to following the ACI strength versus water to cement ratio concept.

A new procedure for designing self-compacting concrete (SCC) mixes with high levels of ground granulated blast furnace slag (ggbs) as a cement replacement material is proposed. The research to produce and validate this procedure comprises three main parts. In the first part, an existing micromechanical model for the plastic behaviour of fluids with inclusions is adapted to compute the …

For producing durable, sustainable and economic concrete, it is necessary to use low w/b ratio in concrete mix and also use secondary cementitious materials as part replacement to cement. Of the various SCMs, replacement of cement by GGBS is permitted to a maximum of 70%. Thus, it helps in producing sustainable concrete.
