. Portland Cement with 53 grade is considered for the concrete mix. This study represents the effect of presence of mineral admixture micro fine GGBSGGBS partially replaced added in cement concrete for evaluating the workability and strength of concrete along with flexural split tensile strength. All abbreviations and acronyms in the mix design sheets are those used in BREs 1992 method.

For cement in concrete 1. 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. It is off white in colour and has fineness in the range of 400 to 600m³kg.

For eg a concrete mix of proportions 124 means that cement fine and coarse aggregate are in the ratio 124 or the mix contains one part of cement two parts of fine aggregate and four parts of coarse aggregate. Of Civil structural engineering SVR college of Engineering Technology AyyaluruV Nandyal Kurnool Dist Andhra Pradesh. Paste volumes in the range 30 - 33 were found not to influence the compressive strength but did influence the consistency of the mixes.

J The consideration of air content in. Therefore Mix Ratio of M35 Grade concrete by weight is Cement. Ordinary Portland cement has been replaced by 47 Ground granulated blast furnace slag GGBS and 59 Micro-silica in order produce sustainable concrete with high durability and better mechanical properties.

Of ingredients of a concrete mix is in the terms of parts or ratios of cement fine and coarse aggregates. To study the mechanical behavior of concrete with GGBS tests on. The geopolymer concrete dry density varied from 2400 to 2500 kgm 3 for 100 GGBS0 fly ash binder proportion and for remaining proportions it varied from 2300 to 2400 kgm 3 which is likely to be conventional concrete.

Anatha Venkatesh2 1PG Student Dept. The coarse and fine combined ag-gregates may be selected to match the standard grading curves used in the design of Portland cement concrete mix-tures. 53 Effect of Variation of GGBS on Flexural Strength The flexural strength of.

Generally. Also with an addition of admixtures great improvement in the pore structures also compactability was found to be affected by the characteristics of the materials and the mix proportions hence it is necessary to arrive the proper mix design procedure. To find the design mix ratio divide the calculated value of all materials by the weight of cement.

For instance the coarse aggregates 70 may comprise 776 kgm3 60 of 20 mm aggregates 518 kgm3 40 of 10.
