Replacement Of Cement By Ggbs In Concrete

Ggbs cement can be added to concrete in the concrete manufacturer s batching plant along with portland cement aggregates and water.

Replacement of cement by ggbs in concrete.

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. Concrete is consumed in large quantities in construction. 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. On the other hand it also contributes to environmental protection because it minimizes the use of cement during the production of concrete.

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. Similarly low cement content concrete kerb backing etc the reduction will be magnified. The reduction in early strength will be more noticeable at high ggbs levels and low temperatures.

Chapter 5 of the book is dedicated to the sustainability of cement concrete and cement replacement materials in. The effect of ggbs and fly ash as partial cement replacement was examined on concrete cubes cylinder and beams. 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. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged.

How ggbs cement is used. Ggbs is used as a direct replacement for portland cement on a one to one basis by weight.
