3. Evaluation of efficiency. This paper attempts to assess the cementitious efficiency of GGBS in concrete at the various replacement percentages through the efficiency concept by establishing the variation of the strength to watertocementitious materials ratio relations of the GGBS concretes from the normal concretes at 28 days.
The main objective of this research was to develop ultrahigh performance concrete (UHPC) as a reliable, economic, low carbon foot print and durable concrete overlay material that can offer shorter traffic closures due to faster construction.

desired concrete characteristics. Highperformance concrete (HPC) does not necessarily require high strength but the mix proportioning should be such that permeability is as low as possible for the particular use. Mix design of high performance concrete is different from that of usual concrete because waterbinder ratio is very low and it may
BENEFITS OF USING GGBS The major benefits of using GGBS are: better workability, making placing and compaction easier lower earlyage temperature rise, reducing the risk of thermal cracking in large pours high resistance to chloride ingress, reducing the risk of reinforcement corrosion 9 10.
Ground granulated blast furnace slag (GGBFS) has become an important constituent material for the design of normal strength and highperformance concrete. Existing literature does not provide the detailed investigation of the residual mechanical properties at high temperatures of concrete .

space constraints, the fast track construction schedule and the densely populated area. High performance concrete and temperature control concrete is made available through inhouse plants and other grades (M40, Lean concrete) are sourced from outside. Design mix keeps on changing during construction due to the variability in raw materials.
HIGH PERFORMANCE CONCRETE WITH GGBS AND ROBO SAND. ROBO sand: ROBO sand or crusher dust obtained from local granite crushers was used in concrete to cast the cubes and cylinders. The bulk density of ROBO sand or crusher dust is 1768 kg/m3. The specific gravity and fineness modulus of ROBO sand are and respectively.

•This presentation investigates the use of tripleblend cementitious mixtures with silica fume, now widely used in the production of high performance concrete. •These high performance tripleblend mixtures are often comprised of Portland cement + fly ash + silica fume, or Portland cement + GGBS + silica fume.
Ultrahigh performance concrete (UHPC) usually contains a very high proportion of ordinary Portland cement which . requires a high amount of energy for its production. The present investigations aimed at systematically developing UHPC produced with supplementary cementitious materials to achieving strengths above 150 MPa at an age of 28 days under

Comprehensive performance data are available for aircooled blast furnace slag and work is continuing to obtain performance data and appropriate specifications for manufactured sand. In other construction applications such as pavement, roadbase and subbase, there is limited information on the performance of
