Sulfate attack is one of several mechanisms of concrete deterioration. An excess of sulfate leads to detrimental chemical and physical changes in the concrete, resulting in increased porosity and permeability and decreased mechanical properties of the concrete. This book provides a comprehensive reference to this important subject, covering: a short history of concrete deterioration due to sulfate attack; the origin of sulfates in concrete; the importance of appropriate concrete processing; forms and physical-chemical mechanisms of concrete deterioration due to sulfates; preventative...

This volume contains reviews on five different aspects of bioclimatology: (1) The establishment, maintenance and use of data from automatic weather station networks for agricultural purposes; (2) Techniques for estimating global and ultraviolet irradiance at the earth's surface, and the net radiation balance from operational satellite observations; (3) Mathematical models of the effects of climate on energy and mass balance in crop production; (4) Paleoecological and experimental studies of the response of stomatal density to changes in the atmospheric CO2 concentrations; and (5) The sensory...
