1.3.1 The Variation of Temperature of Mass Concrete with Time Because of the large size, the variation of temperature in a mass concrete structure is shown in Figure 1.3; the placing temperature Tp is the concrete temperature just after pouring. If the concrete cannot be completely cooled, it...
In order to reduce the risk of slab cracking, the concrete surface should be paved when the base temperature is low; within 48 h after concrete pouring, the maximum principal stress growth rate caused by the high base temperature is much greater than the tensile strength. During this period,...
The utilization of cooling pipes is another approach as pipes are pre-installed into the pouring area and allow for complete control over the concrete elements’ temperature. Keeping the temperature gradient minimal in a mass element is key to achieving a durable concrete structure. How to ...

The results show that it Can effectively prevents the slab foundation structure cracking and achieves good results through controlling Concrete materials and concrete temperature Parameter such as the lifting machine temperature and the pouring temperature and the expansion joint or the whole pouring length...
The temperature response of pavement is not only crucial for assessing the internal stresses within pavement structures but is also an essential parameter in pavement design. Investigating the temperature response of rubberized concrete pavements (RCP) can support the construction of large-scale rubber co...
Therefore, the concrete specimen in this experiment was equivalent to the core part of a thin-walled concrete slab, with just 2% consumption of concrete, as shown in Figure 1. The material components and corresponding proportions of the concrete specimen are detailed in Table 1. Figure 1. ...
