Book Description
Studies were made of the effects of varying concrete production methods upon potentially durable concrete. Variations in the surface porosity, strength and air void system produced by differing finishing techniques were evaluated for typical air-entrained concretes. Large and small scale specimens were cast and effects of period and time of finishing, environmental conditions, and additions of water during finishing were evaluated using surface scaling tests, surface tensile strength tests and microscopical determination of surface air void parameters. If a concrete is to remain durable when deicing agents are used, it must have proper air entrainment and curing.

Book Description
This book forms the proceedings of the international workshop to be held in Essen, Germany. This workshop summarises the conclusion of the technical committee's investigations into the resistance of concrete to freeze-thaw attack, specific in this to resistance with or without de-icing chemicals. It presents the RILEM recommendations on testing the freeze-thaw and de-icing salt resistance of concrete.

Book Description
Deicing agents for removal of ice and snow from highways and streets are essential to wintertime road maintenance in most areas of the U.S. Due to the ever-increasing use of highway deicing materials, there has been growing concern as to environmental effects resulting from these practices. The state-of-the-art report critically reviews the available information on methods, equipment and materials used for snow and ice removal; chlorides found in rainfall and municipal sewage during the winter; salt runoff from streets and highways; deicing compounds found in surface streams, public water supplies, groundwater, farm ponds and lakes; special additives incorporated into deicing agents; vehicular corrosion and deterioration of highway structures and pavements; and effects on roadside soils, vegetation and trees. Highway deicing can cause injury and damage across a wide environmental spectrum. Recommendations describe future research, development and demonstration efforts necessary to assess and reduce the adverse impact of highway deicing.

Book Description
Investigation was conducted to develop a simple and fast test that could be used to identify aggregates that cause poor concrete performance when frozen. A one-cycle slow- freeze test was developed and evaluated by correlating results with the durability factor obtained from astm method c290 (the standard freezing and thawing test in water). The test method and testing procedures are presented in detail.
