Title: Strength Losses in Heat Curing- Causes and Countermeasures
Author(s): Johan Alexanderson
Publication: Special Publication
Appears on pages(s): 91-108
Keywords: concretes; cracking (fracturing); curing; high temperature; porosity; strength; tensile strength; thermal expansion; voids
Abstract:An investigation is discussed which had as its aim the clarification of the causes of strength loss in heat cured concrete as compared with normally cured concrete. It is concluded that the dominant causes are of a physical nature, i.e., increased porosity and cracking, which can be the result of the pressure which occurs in the air pores upon heating. Criteria for the occurance of cracking have been formulated and with the aid of these the minimum tensile strength necessary to avoid cracking can be determined.
