The engineering application results also show it is financially viable that adopting the normal Portland cement to manufacture the heat-resistant concrete with limit heat-resistant temperature of 500℃.
Engineering application Based on the experiment results of the mix proportion, the best mixture ratio of the heat-resistant concrete is No.1 specimen which was listed in Table 6.
Engineering application of heat-resistant concrete shows that the heat-resistant concrete which was produced by using normal Portland cement meets the requirement.

It is significant for freezing process and freezing units, optimum design of practical engineering.
Introduction Soil freezing is a common natural phenomenon, it is disserve for industrial and civil buildings of permafrost areas.
Using the finite difference prediction of soil freezing time may be right permafrost zone-based engineering and construction to withstand freeze-thaw cycles endurance and longevity study to predict, and thus the basis for the design of high-rise building theory.

Secondly, how to calculate claim value by contract status analysis was studied and finally it was proved by an engineering practice.
It can provide references for the further engineering practices.
It is indicated by some statistical data that claim can bring about more than a billion dollars for civil engineering per year.
· “Contract status” defines a completed and systematical engineering plan.
However, the work was suspended for 2d because the Engineer failed to apply variation plan to the Contractor.
