Here mainly consider five key elements such as materials, machinery, human resources, method of operation and construction environment.
Moreover, in the construction process, we use a variety of construction materials.
Another is to do the testing and inspection of the sample standard, which can regulate the quality of construction materials, and also improve approach material standards and technical requirements.
Receiving clerk's duty is to check the materials, so the supervision engineer must complete all these aspects of routine inspections.
As a result, the operators will be able to grasp the engineering characteristics, the purpose of the design and key parts of the quality standards.

Firstly, based on result of core testing under normal temperature, I determined the best mix-proportion for three materials, and tested their shear, tensile strength, deformation performance under different temperature and humidity.
