Concrete is the most versatile, indispensable and widely used building material, of which cement is an integral constituent. From the time immemorial Portland cement has been used as binder in concrete construction. However, the production of the cement is not ecofriendly and consumes enormous amount of energy which ultimately leads to the depletion of the fossil fuel reserve.
Aug 16, 2007· Slag cement is a wonderful material to work with, from 4,000 psi concrete to 15,000 psi concrete. I''ve used 50% in 13,000 psi concrete and it works beautifully. Don''t be afraid to use 30% or 40%, you won''t be sorry.
The present paper focuses on investigating characteristics of M20 and M40 grade concrete with partial replacement of cement with ground granulated blast furnace slag (GGBS) by replacing cement via ...
This PhD thesis focuses on the use of blastfurnace slag (BFS) as cement replacing material. Blastfurnace slag, a byproduct of the steel production, obtains latenthydraulic properties after rapid cooling and can thus replace clinker in cement.

The use of pozzolanic materials in cement concrete paved a solution for the properties of the concrete the concrete production cost the scarcity of cement economic and advantageous disposal of industrial wastes. STRENGTH DEVELOPMENT IN CONCRETE BY INCORPORATING METAKAOLIN
Compared to PC, the slower strength development in PCSlag cement resulted in smaller autogenous shrinkage reduction. Drying shrinkage reduction was observed at an early age in both PC and PCSlag unrestrained cement paste containing the MgOs at watertobonder (w/b) ratio of, although the longterm shrinkage was higher than the control.

An interesting paper by Bakharev et al. (2000) tried to rationalize the study of workability of concrete that incorporated alkaliactivated slag as the only binder. The activators were liquid sodium silicates (4 ± 7% Na, mass of slag) and a multicompound activator (NaOH + Na 2 CO 3) (8% Na, mass of slag).To ameliorate the workability, measured by the slump loss test, different additives have ...
Self Compacting Concrete. Selfcompacting concrete (SCC) is a special type of concrete which can be placed and consolidated under its own weight without any vibration effort due to its excellent deformability, and which at the same time is cohesive enough to .

Slag cement is a recovered byproduct of the iron manufacturing process and can be used to replace a portion of portland cement in concrete mix design. The use of slag cement has demonstrated longterm performance enhancements allowing designers to reduce the environmental footprint of concrete while ensuring improved performance and increased ...

Cement for their generosity and supply of all concrete constituent materials used for this study. I would like to thank the PhD examination committee members, Professor K. Riding, Professor D. Panesar, Professor K. Peterson, and Professor F. Azhari for their comments.
Concrete is probably the most widely used construction material in the world. In the Arabian Gulf region, deterioration of concrete due to the aggressive environment is recognized to be the main factor affecting their structural integrity. The durability of concrete structures can be preserved by various protection methods; however, using cement replacement materials is one of the most ...

SCIC #11, Slag Cement and Fly Ash, compares the two materials, explaining that while chemical similarities exist between them, they exert different influences in concrete applications. Slag cement is a hydraulic cement while fly ash is a pozzolan. This information sheet lists the properties slag cement can bring to concrete in both plastic and ...
The environmental concerns related to the production of cement in terms of the energy consumption and the emission of CO2 lead to the search for more environmentally viable alternatives to cement. One of those alternative materials is alkaliactivated slag (AAS) where ground granulated blast furnace slag is used not as a partial replacement to cement but as the sole binder in the production of ...
