This study evaluated the effects of temperature on the strength and permeability of concretes containing pozzolans (fly ash and silica fume) and slag. Two test programs were conducted. In the first, one control and five experimental mixtures containing silica fume, fly ash, or slag were evaluated. In the second, one control and three experimental mixtures containing fly ash or slag at a higher water-cementitious material ratio (W/CM) than used in the first program were evaluated. Concretes cured at higher temperatures had higher strengths up to 28 days but lower strengths at 1 year. Permeability decreased with time. Increasing early curing temperatures enabled the achievement of lower long-term permeability for 6 months and beyond at 28 days. Concretes containing a pozzolan or slag had a lower long-term permeability than the control. Adding a pozzolan was more effective in reducing permeability than reducing the W/CM. At cold temperatures, if the specified properties are not achieved, the contractor should change the mix design and/or provide insulating blankets and/or external heat to ensure the desired product.

Concrete made using mineral cements, the raw materials which on earth are practically endless, is known as one of the oldest building materials and during the last decades of the twentieth century has become a dominant building material for general use. At the same time, the requirements of the quality of concrete and its performance properties, in particular compressive strength, durability, economical efficiency, and low negative impact of its manufacture on the environment have not yet been completely met. Bearing these requirements in mind, researchers and engineers worldwide are working on how to satisfy these requirements. This book has been written by researchers and experts in the field and provides the state of the art on recent progress achieved on the properties of concrete, including concrete in which industrial by-products are utilized. The book is dedicated to graduate students, researchers, and practicing engineers in related fields.
