Table 4 shows mixture proportions of concrete for freeze and thaw testing. Ordinary Portland cement (Density: /cm3, Blaine fineness: 3,300cm2/g) and ground granulated blast furnace slag (Density: /cm3, Blaine fineness: 4,150cm2/g) are used as a
The concrete contained a normal total cementitious content of 390kg/m and had different levels of ground granulated blast furnace slag in the range 0, 30, 50 and 70% by weight as replacement material for portland cement. Some of the concretes were prepared using gravel and others with crushed limestone as aggregate.
DURABILITY OF PORTLAND BLASTFURNACE SLAG CEMENT CONCRETE. This paper summarizes the results of studies carried out at the Building Research Establishment in the UK, on the performance and longterm durability of concrete where ground glassy blastfurnace slag (granulated and pelletized) has been used as a cementitious material.
#0183;#32;The concrete cubes were photographed, and their sulfate attack ratings and compressive strengths measured at 1, 2, and 5 years. The results showed that concretes made with ground granulated or pelletized blast furnace slag and portland cement generally had good sulfateresisting properties when the slag content was 70 percent and above.

#0183;#32;Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties. In this article we []
Figure4: Blast Furnace Slag Particles. Permeability of concrete incorporating slag. It is claimed that, concrete incorporating slag perform better in terms of permeability compare with controlled concrete because blast furnace slag in cement paste decreases the size of pores and consequently the permeability of slag concrete is declined.

When substituted for portland cement in quantities between 25% and 65%, slag cement plays a vital role in reducing permeability in concrete. SCIC #6, Reducing Permeability, explains how lowpermeability concrete has a reduced potential for corrosion of reinforcing steel, and provides a brief discussion of how standard test method ASTM C1202 measures permeability.
Geoffrey Osborne, OBE, formerly Head of Concrete Durability Section at the Building Research Establishment, UK where he worked for over 40 years. Main research interests include: studies on properties of Portland and high alumina cements, their use with blastfurnace slag and pozzolans and longterm durability of concrete.
