Replacement Of Cement By Ggbs In Concrete

Chapter 5 of the book is dedicated to the sustainability of cement concrete and cement replacement materials in.

Replacement of cement by ggbs in concrete.

The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. In this research paper we have kept percentage of fly ash for every trial constant except for conventional trial and ggbs was used to replace cement partially from 40 up to 70 while keeping fly ash 25 as constant throughout. From structural point of view ggbs replacement enhances lower heat of hydration higher durability and higher resistance to sulphate and chloride attack when compared with normal ordinary concrete. Each human being consumes one tonne of concrete per year which makes it the substance with the second highest consumption only water is higher concrete centre 2003.

With the addition of 40 of ggbs as a replacement of cement for an m25 grade of concrete there is an increase in the strength compared to the normal concrete. How ggbs cement is used. Ggbs cement can be added to concrete in the concrete manufacturer s batching plant along with portland cement aggregates and water. On the other hand it also contributes to environmental protection because it minimizes the use of cement during the production of concrete.

Similarly low cement content concrete kerb backing etc the reduction will be magnified. Concrete is consumed in large quantities in construction. The effect of ggbs and fly ash as partial cement replacement was examined on concrete cubes cylinder and beams. An experimental investigation on properties of concrete by partial replacement of cement with ggbs and fine aggregate with quarry dust dr.

As ggbs is partially replaced with the cement the consumption of the cement is reduced and also the cost of construction is reduced. Mallikarjuna in the present study an investigation is made on properties of concrete by partial replacement of cement with ground granulated blast furnace slag ggbs and fine.
