The hardened properties of said concrete mixes when compare both. For example 70 of cement.

Maximise cementitious addi tions in footings or other locations where.

. The GGBS properties were confirmed to IS269-1976. Ground granulated blast furnace slag GGBFS is broadly utilized as a mineral admixture in concrete production. On the basis of present work we found that GGBS in concrete improves workability compressive strength flexural strength split tensile strength and decreases the density water absorption.

The concrete slump test measures the consistency of fresh concrete before it sets. Cement Flyash Sand Aggregate Water and Superplasticizer needed for M35 grade concrete. 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 cement in concrete 1. No t as per Result BS6699 The mix proportions of M-60 concrete for 1m3 along Chemical with GGBS are tabulated in the table. To obtain Mix proportions of OPC concrete for M20 by IS method 10262-2009.

36Mix design and mix details. Sand coarse aggregate water and GGBS. Granulated blast furnace slag GGBS as a filler material.

This study shows a procedure for the optimal design of a sustainable. Characteristics Requiremen Test Ordinary Portland Cement. The GGBS used in the research was brought from a steel plant in Mangalore.

The design formulation is based on the IS CODE 10262-2000 for M 40 grade of concrete Fck40Mpawater cement ratio. Properties of GGBS 35 Mix Design.

To calculate the mix proportion with partial replacement such. To find the design mix ratio divide the calculated value of all materials by the weight of cement. Portland Cement with 53 grade is considered for the concrete mix.

Initially the dry materials Cement Aggregates Sand are mixed. To study rheological properties of concrete mixes having GGBS and Steel Slag. Than0control mix at056 days.

It is off white in colour and has fineness. Compressive strength values of the GGBS. In concrete GGBS ranges typically from 30-40.

GGBS will usually replace between 30 and 70 of cement in the concrete although that figure can go up to as high as 85. After the mix design the proportions were arriving and tabulated in table 21. And 30 replacement of GGBS is greater than the 50 replacement of GGBS.

Strength of alkali activated concrete AAC produced with fly ash FA and ground granulated blast furnace slag GGBS have been investigated with the aim of developing a suitable mix. The need to consider the interaction of biological and chemical. The geopolymer concrete dry density varied from 2400 to.

GGBS Concrete Mix Design. The mix design of self compacting concrete calculations are done as per IS10262. It is performed to check the workability of freshly made concrete and therefore the ease with.

For concrete pavements it is recommended that the proportion of. The quantity of GGBS cement must be between 6 and 65 in order to comply with BS 8500-1. It usually replaces cement in exactly the same quantity ie.

Mix Design Procedure In this study we are considered M25 for the source of Self Compacting Concrete. 53 Effect of Variation of GGBS on Flexural Strength The flexural strength of concrete is tested for 28 days. The combination of fly ash and GGBS is a possible solution for producing GPC even under outdoor curing condition.

For both casting and curing of concrete. Design of durable concrete wastewater infrastructure and has significant implications for public expenditure in this area. Nan Su method is being used for mix design optimum mix proportion finalised with 10 percent GGBS as replacement for cement at.
