Treval Clifford Powers
Treval Clifford Powers (1900-1977) was a 20th-century materials scientist considered "the father of the modern science of cement-based materials." He made contributions to the understanding of the structure of fresh and hardened cement paste and achieved fundamental results on concrete rheology, workability, consistency, durability, shrinkage and swelling, creep, and resistance of concrete to frost, sulfates and abrasion. He was the father of systems theory pioneer William T. Powers. Born on February 8, 1900, in Palouse, Washington, Powers studied chemistry at Willamette University in Salem, Oregon, a small private college founded in 1846. From 1930 until his retirement in 1965 he conducted research at the famouPCA (Portland Cement Association)Laboratories (located initially in Chicago and later in Skokie, Illinois Skokie (; formerly Niles Center) is a village in Cook County, Illinois, United States, neighboring the City of Chicago's northern border.

Cement Paste
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime or calcium silicate based, which can be characterized as hydraulic or the less common non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble and so are quite durable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skokie, Illinois
Skokie (; formerly Niles Center) is a village in Cook County, Illinois, United States, neighboring the City of Chicago's northern border. Its population, according to the 2020 census, was 67,824. Skokie lies approximately north of Chicago's downtown Loop. Its name comes from a Potawatomi word for "marsh." For many years, Skokie promoted itself as "The World's Largest Village." Skokie's streets, like that of many suburbs, are largely a continuation of the Chicago street grid, and the village is served by the Chicago Transit Authority, further cementing its connection to the city. Skokie was originally a German-Luxembourger farming community, but was later settled by a sizeable Jewish population, especially after World War II. At its peak in the mid-1960s, 58% of the population was Jewish, the largest proportion of any Chicago suburb. Skokie still has many Jewish residents (now about 30% of the population) and over a dozen synagogues. It is home to the Illinois Holocaust Muse ...
