Classification of Waterproofing Grade of Concrete Roof Engineering
Waterproofing grade is widely used to characterize the performance,importance,construction and material performance in waterproof engineering,which is beneficial to the use of engineer,but its definition,attribute and grading basis have been controversial.Based on the key index system of waterproof engineering,it can be seen that the waterproofing grade has objective and result attributes.The waterproof failure probability calculation program is used to carry out combined calculation and analysis on different types of waterproofing materials,constructions and environments.It shows that the waterproofing grade can be classified based on the waterproofing failure probability.
