    en.wikipedia.org/wiki/William_Aspdin

    William had discovered that a significantly different product, with much wider applications, could be made by modifying his father's cement formulation. By increasing the limestone content in the mixture, and burning it much hotter, a slow-setting, high-strength product suitable for use in concrete could be obtained. This product was ...

    The Chinese followed the state rules for thousands of years so many of the ancient, surviving buildings were built with the methods and materials still used in the 11th century. Chinese temples are typically wooden timber frames on an earth and stone base. The oldest wooden building is the Nanchan Temple (Wutai) dating from 782 AD. However ...

    Romans mixed powdered limestone, volcanic ash found from Mount Vesuvius, and water to make a cement paste. [5] A volcanic peninsula with stone aggregates and conglomerates containing crystalline material will produce material, which weathers differently from soft, sedimentary rock and silt. With the discovery of cement paste, structures could ...

Fire is an essential tool for human survival and the use of fire was important in early human cultural history since the Lower Paleolithic .

  9. John Smeaton - Wikipedia

    en.wikipedia.org/wiki/John_Smeaton

    Smeaton is important in the history, rediscovery of, and development of modern cement, identifying the compositional requirements needed to obtain "hydraulicity" in lime; work which led ultimately to the invention of Portland cement. Portland cement led to the re-emergence of concrete as a modern building material, largely due to Smeaton's ...
