Excerpt from Comparison of the Compressive Strength of Concrete Made With Limestone Screenings and With Torpedo Sand: A Thesis
Most of the railroads of Chicago are now engaged in elevating their tracks. Of course retaining walls are needed to keep the tracks of the companies within their respective rights of way, and these walls have been made of different materials. 'they were first built of rubble masonry and the abutments at right angles to the tracks, being placed on each side of street subways, of ashlar. The work on such walls was necessarily slow and expensive, as they had to be in perfect alignment and of course skilled masons were employed to build them.

Paperback. Condizione: New. Print on Demand. This book explores the comparative strength and structural integrity of concrete made with limestone screenings versus torpedo sand as a matrix. The results of extensive testing are presented, and the author concludes that concrete made with limestone screenings exhibits greater compressive strength than concrete made with torpedo sand, particularly as the concrete ages. The author theorizes that this is due to a natural cementatory property in the screenings and their ability to pack more closely together, reducing voids and creating a more uniform concrete matrix. The book also examines the historical use of screenings in concrete structures and presents the opinions of engineers regarding their efficacy. Ultimately, the book's insights demonstrate the potential of limestone screenings as a valuable and cost-effective alternative to sand in concrete production.
