Efficiency of GGBS in concrete - ScienceDirect
The present paper is an effort to quantify the 28-day cementitious efficiency of ground granulated blast furnace slag (GGBS) in concrete at the various replacement levels. It was observed that this overall strength efficiency of GGBS concretes can also be defined through a procedure adopted earlier for other cementitious materials like fly ash ...

principles of concrete mix design.ppt - ACC Help
Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened states. In general, concrete mixes are designed in order to achieve a defined workability, strength and durability . The selection and proportioning of materials depend on: 34

Strength of Concrete vs Grades of Cement
Cements of different grades viz. 43 OPC (IS–8112) 1, 53 OPC (IS-12269) 2 and Portland Pozzolana cement (fly ash based), IS-1489 Part I 3 etc. with different brand names are available in the market. However, when tested in the laboratory these cements do not give the strength corresponding to their grades in case of OPCs and markings such as 43 MPa 53 MPa on their bags in case of Portland ...

What is GGBS? Its Advantages and Disadvantages ...
What is Ground Granulated Blast Furnace Slag (GGBS)? The ground granulated blast furnace slag (GGBS) is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength, and durability.. This material is obtained by the heating of the iron ore, limestone, and coke at a temperature of about 1500 o C. The process is carried out in a blast …
