China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

Following the successful implementation of the MLD project in South Africa, the MLD® technology independently developed by the National Center for Quality Inspection and Testing of Cement under CTC has successfully landed at two cement enterprises in Dondo and Nacala, Mozambique!

Overseas factories of Chinese cement enterprises generally face common challenges such as weak basic laboratory conditions, a shortage of professional testing personnel, difficulties in procuring chemical reagents, low efficiency of wet analysis, and pressure from waste liquid disposal, which constrain production quality control levels.
In response to the actual needs of the two cement enterprises in Dondo and Nacala, Mozambique, the National Center for Quality Inspection and Testing of Cement provided them with a complete MLD® testing solution. The project team also provided full-process localized technical services, carrying out systematic training on fusion bead sample preparation, software operation, equipment operation and maintenance, and daily quality control. After short-term training, local staff can independently complete the entire testing process of sample preparation, instrument testing, and data interpretation.
The solution effectively resolved the enterprises' pain points of insufficient laboratory personnel, unstable testing accuracy, and slow analysis speed, reduced dependence on chemical reagents, and avoided reagent procurement and storage difficulties. Frontline laboratory and management personnel commented that the solution is easy to operate, highly efficient in testing, and stable and reliable in data, providing solid support for the enterprises' routine quality monitoring and closed-loop production control.

MLD® technology is a new fusion-based X-ray fluorescence analysis method that can achieve rapid and accurate chemical composition analysis of various samples such as cement, raw meal, clinker, gypsum, iron raw materials, siliceous raw materials, industrial waste slag, and solid waste, and can simultaneously detect 14 key components (silicon, aluminum, iron, titanium, calcium, magnesium, sulfur, potassium, sodium, manganese, phosphorus, chromium, zinc, and chlorine). The application of this technology requires no complex sample pretreatment, and laboratory personnel can take up their posts after short-term training. The daily sample testing efficiency is 20 times higher than that of traditional wet methods, and no strong acids or alkalis are used throughout the process, providing an integrated solution for enterprises to improve quality control levels, reduce comprehensive testing costs, and achieve green and safe production.
The technology has successively won the Building Materials Science and Technology Award of the China Building Materials Federation and the Chinese Ceramic Society, and the Science and Technology Award of China National Building Materials Group. It was successfully included in the “Catalogue of Technologies and Products Encouraged for Promotion and Application in the Building Materials Industry (2025 Edition).” It has now been applied in multiple cement group enterprises such as Huaxin, China Resources, Tianshan Materials, BBMG Jidong, Shanshui, Gezhouba, Yufeng, Tapai, Hongshi, and Gaozheng, laying a solid foundation for overseas promotion.
From the first stop in South Africa to the dual-line commissioning in Dondo and Nacala, Mozambique, the application of MLD® technology in Africa continues to expand, helping enterprises simultaneously improve testing quality and testing efficiency. In the future, the team will continue to refine the technology and improve the overseas standardized delivery and training system, provide efficient and green testing solutions for more overseas cement enterprises, and promote China's independent testing technology to the world.
