| 摘要： | This report describes the use of tables developed to help determine problems that may result from early thermal effects in concrete. The thermal behavior of concrete can be estimated from a knowledge of concrete temperature, air temperature, type of cement, and content of cement in the mixture. The thermal effects tables can be used to predict whether too high a temperature will be reached in the pavement; whether early thermal cracking will result from larger differences between the temperature of the concrete slab and the temperature of either the air or the base; or whether there is a risk of early cracking of the concrete. Examples of the use of the table are given along with guidelines for avoiding undesirable thermal effects. |
