What is the manufacturing process of Portland Cement?
The name Portland cement is recorded in a directory published in 1823 being associated with a William Lockwood and possibly others. In his 1824 cement patent, Joseph Aspdin called his invention “Portland cement” because of its resemblance to Portland stone. However, Aspdin’s cement was nothing like modern Portland cement, but was a first ...
