Theslagcontent of the binder varied from 0 % to 100 % of the weight of thecement. Thecement-aggregate ratio in the experiments was 1:15 and the water-cement+slagratio was 5.9. The compressive strength of themining-fill-concrete was determined at the age of 28, 91 and 182 days. The specimens were cured at both +8 OC and a t +20 oC.Get Price
Slag cement (also called ground granulated blast furnace slag) is a hydraulic cement produced during the reduction of iron ore to iron in a blast furnace. Molten slag is tapped from a blast furnace, rapidly quenched with water ("granulated"), dried and ground to a fine powder. The rapid quenching "freezes" the molten slag in a glassy state, which gives the product its cementitious properties.Get Price

Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed.Get Price
TheCement-Bentonite slurry typically consists of a mixture of blast furnaceslag, Portlandcement, bentonite clay and water and is sometimes referred to as simply acement-bentonite wall.
