A Comparison of the Chemical and Physical Properties of Vitrified Bricks

Excerpt from A Comparison of the Chemical and Physical Properties of Vitrified Bricks: A Thesis The striking increase in the use of vitrified bricks for paving purposes, has caused the industry to become one of utmost importance. Paving brick are rapidily replacing asphalt and even granite on streets where heavy teaming occurs. Although the use of paving brick is very extensive, it began at a comparatively recent date, and the standardizing and developing of the various tests is, even yet, in an unsatisfactory condition, so that the quality of the brick is not always determined by the tests put upon it. The chemical analysis of brick has, heretofore, had little to do to control the quality of the pro - duct obtained, manufacturers simply using the raw material as it was mined. The aim of this thesis is to attempt to establish some relation between the chemical and physical properties of vitrified brick; to try to show what effects different amounts of any substance, as shown by the chemical analysis, have upon the quality of the brick as determined by the standard physical tests. While we were unable to compare, in this manner, as many different kinds of brick as we wished, still we feel that the conclusions we have drawn at the end of this paper are general enough to in - About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
