Effect of Partial Replacement of Cement by Silica Fume on Hardened Concrete

The use of Silica Fume (SF) in short period of time had one of the most dramatic impacts on the industry’s ability to routinely and commercially produce SF modified concrete of flowable in nature but yet remain cohesive, which in turn would develop both high early and high later-age strengths including resistant to aggressive environments. This paper features an experimental study on the nature...

Replacement of Cement in Concrete

Cement is a binding material, a substance that sets and hardens independently, and can bind other materials together. In ancient civilization the binding materials were of traditional type such as jaggery, lead, jute, rice husk etc, now in modern civilization cement is main binding materials. The use of concrete containing high volume fly-ash has recently gained popularity as a resource efficie...

Light-hardened luting cement for orthodontic bands and appliances.

Use of Vitremer Core Buildup/Restorative Cement (3M Dental Products Division) as a luting cement for orthodontic bands and space maintainers was described in 1994. For use as a luting agent, the restorative cement is mixed with a slightly lower powder liquid ratio so the blend is more fluid than one used for a dental restoration. A chief advantage of using Vitremer Restorative Cement for luting...
