The Rise of Portland Cements [PDF]
This chapter tells the story of Portland cement, from its invention in the 19th century until its present-day hegemony as the number one manufactured mineral product. The success story of Portland cement is rooted in the unique combination of the abundance of its raw materials, the reactivity of the high-temperature clinker product toward water, and ...

Structural Performance of Laterite soil Stabilised with Cement and Blue Gum (Eucalyptus Globulus) Wood Ash for Use as a Road base Material [PDF]
This study examines the effect of partially replacing cement with blue gumwood ash (BGWA) in stabilizing laterite soil to be used as a potential road base material. Initially, Ordinary Portland Cement was introduced to the soil at varying contents from 0 to 12% in steps of 3% by weight of the soil sample.
