ResumoA CENTURY ago, Joseph Aspdin, an obscure mason of Leeds,1 England, was granted a patent by King George IV on an artificial stone which he called cement, because of its resemblance to the well-known building stone quarried on the Isle of Portland,-tbe stone of which Westminster Abbey was constructed. According to the fragmentary history of Joseph Aspdin, his patent followed years of experimenting, so that the present cement industry, which has developed from Aspdin's factory of 1825, was founded upon research. His plan of combining two powdered raw materials in certain proportions, burning them and then pulverizing the resulting clinker produced a cement much superior to the older hydraulic cements which were made from a single material that was lightly burned and then ground. The industry's surprising growth since Aspdin's time has been based largely on that same factor; today scientific research into the constitution and manufacture of Portland cement and its use in making concrete is going forward on a still more extensive scale.
