  • Concrete Set Time Slag Cement

    How Does Slag Cement Affect Time of Set? At temperatures less than 85 degrees Fahrenheit, concrete containing slag cement can have longer times of set, when compared with 100 percent portland cement concrete. The lower the ambient and/or concrete temperatures, the slower the set times will be (Figure 1).

    If the slag cement particles are finer than the Portland cement particles, the rate of bleeding will decrease, and in contrast, if the slag cement particles are coarser than the Portland cement particles, bleeding will increase when substituted on an equal-mass basis. The setting time of concrete containing slag cement is commonly retarded.

  • Slag Cement Questions

    Slag cement will tend to increase time of initial set, which is often a benefit in warm weather. In cooler weather, accelerators, heated materials or lowering the percentage of slag cement in a mixture (as a portion of cementitious material) can be employed to decrease times of set (see SCIC #3).

    03/09/2020· Slag cement has actually been used in concrete projects in the United States for over a century. Its earliest use was documented in 1774, when it was combined with slaked lime and used as a mortar.This cement was first used commercially in Germany in the 1860s, and it was such a success that engineers in 1889 decided to build the Paris underground metro using slag-lime cement.

    22/09/2016· Gypsum is called the retarding agent of cement which is mainly used for regulating the setting time of cement and is an indispensable component. Without gypsum, cement clinker can condense immediately by mixing with water and release heat. The major reason is that C3A in the clinker can dissolve in water quickly to generate a kind of calcium aluminate hydrate, a clotting agent, which
