General Information
A Professional’s Handbook to Grouting and Concrete Repair
Originally published by FIVE STAR PRODUCTS, INC. in 1981, this edition is an aid to owners, engineers, architects, specifiers and contractors involved in the selection, specification and use of nonshrink grouts and concrete repair materials. This latest version, which is 122 pages, was released in 2012.

Secret to Roman Concrete Revealed : Durability + Design News
The mortars used to bind the structures of ancient Rome consisted of a mixture of 85 percent (by volume) volcanic ash, fresh water and lime, which is calcined at a much lower temperature than modern cement. The mineralogical changes that took place in the curing of the mortar over a period of 180 days were compared to 1,900-year-old samples and it was found that a “crystalline binding hydrate” prevented microcracks from propagating. The mortar resists microcracking through in-situ crystallization of platy strätlingite, a durable calcium-alumino-silicate mineral that reinforces interfacial zones and the cementitious matrix. Most modern concretes are bound by limestone-based Portland cement. Manufacturing Portland cement requires heating a mix of limestone and clay to 1,450 degrees Celsius (2,642 degrees Fahrenheit). The process releases enough carbon—given the 19 billion tons of Portland cement used annually—to account for about seven percent of the total carbon emitted into the atmosphere each year.
Unlocking the secrets of Al-tobermorite in Roman seawater concrete
This highly technical Mineralogical Society of America article from 2013 is about ancient Roman concrete, which is an extraordinarily durable, high-performance composite constructed from lime and pyroclastic rocks. Study of this material has provided insight into ways to make modern concrete more durable.
