ACI SP-62:1979 PDF Download

ACI SP-62:1979 is a collection of 20 papers that provide comprehensive information on the use and applications of superplasticizers in concrete. The papers were presented at an international symposium and cover a wide range of topics related to superplasticizers.

The standard begins by discussing the concept of superplasticized concrete and its significance to the concrete industry. It then goes on to explore the experiences and case histories of superplasticizer usage in different countries including Germany, Japan, Canada, England, and Australia. These case histories provide insights into the benefits and limitations of superplasticizers and highlight their real-world applications.

The standard also includes papers that delve into the technical aspects of superplasticizers, such as their influence on water reduction, slump loss, and air-void systems in concrete. There are laboratory studies and evaluations that examine the effects of superplasticizers on the engineering properties of plain and fly ash concrete. The standard also explores the performance of superplasticized concrete in terms of strength, time-dependent properties, and accelerated curing.

In addition, the standard addresses specific applications of superplasticizers, such as their use in glass fiber reinforced microconcrete and in steam-cured cement-fly ash concretes. The factors influencing slump loss in flowing concrete are also discussed.
