Mechanical Properties of Concretes Containing Super-Fine Mineral Admixtures
The mechanical properties of concretes containing super fine mineral admixtures such as limestone powder, titanium slag, lithium slag and silica ash have been investigated by compression tests. It was found that 10% limestone powder used in cocncrete is beneficial to compressive strength, it reaches 111Mpa after 28 days curing. The optimum mixing amounts of titanium slag, lithium slag and silica ash are 20%, 10% and 10%, respectively. All their 28d compressive strengths exceed 100MPa, reach super-early and super-high strength concrete level. By introducing mineral admixures into concrete, the cement consumption in concrete can be greatly reduced.
