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.

A study was conducted on the influence of low temperature on the properties of hardened air-entrained concrete which was subjected to four different curing conditions. One of the curing conditions was related to the prevalent winter curing practice in Whitehorse, Yukon Territory, Canada. The tests consisted of compression, splitting tension, impact and elastic strains. In total, over four hundred specimens were tested.

This paper discusses winter curing of concrete in the light of the New Canadian Standard. The effect of freezing fresh concrete at various ages is dealt with in some detail and tests results are given to illustrate the absolute minimum protection period and minimum protection methods.
