To ensure quality consistency and quality assurance, Apache Quality Control team has identified 13 sampling points in the whole process control, from limestone quarry to cement outlet. Apache laboratory is equipped with high-tech lab equipment such as XRL X-Ray machine, and performs all related quality control tests by well-trained Quality Control staff. Apache is working to achieve ISO 9001-2008 for its quality assurance.As standard raw materials are crucial in producing the quality products, Apache also gives consideration on the quality of raw materials. Apache sets the norm and standard deviation for each raw material and the assay test is performed before being for the production. For the limestone and other raw materials, the assay test for the chemical compositions and moisture content are performed in each step of the production process to meet with the predefined standard.
