Dong Lam brand cement products have a firm position in the market.

Focus on quality

In business, in addition to customer care policy, product quality is the foundation for building long-term reputation and trust in the brand. With the desire to bring products of good and stable quality, Dong Lam has implemented strict control to ensure the quality of products from the preparation of raw materials, input fuels to finished products.

Mr. Ton That Tung Thanh, Director of Quality and Head of Laboratory - Product Quality Control and Technical Services (Laboratory - Quality Control and Technical Services) Dong Lam said that producing high quality cement, in addition to modern production technology and equipment, good raw materials and additives, also requires strict implementation of control work to ensure product quality.

To meet that requirement, at Dong Lam Cement Factory, a synchronous quality management system was built in accordance with ISO 9001 standards, unifying the management of all processes related to production and quality management activities, including processes from preparing raw materials and fuels to production and consumption of products, and after-sales technical services. Technical standards for raw materials, fuels, semi-finished products and finished products are all built and issued as basic standards (TCCS).

In particular, the quality standards of Dong Lam cement products are built to exceed the standards and technical regulations of the country and international regulations, the quality level is guaranteed to be superior to best meet the needs of customers. Currently, Dong Lam cement with many product lines has quality certified to comply with technical standards according to TCVN 2682:2020, TCVN 6260:2020, TCVN 6067:2018, TCVN7711:2013, ASTM C150 Type I and II, BS EN 197-1.

With a team of laboratory staff from the Laboratory of Testing, Quality Assurance and Technical Services recognized by the National Accreditation Office as having the capacity to meet the requirements of ISO/IEC 17025, quality is strictly controlled from the stage of preparing raw materials, fuels, intermediate products in the production process to the final products for consumption. The results of inspection and testing are reviewed and evaluated for conformity with the technical requirements set forth by the company. Accordingly, the products of each production stage must meet the technical requirements specified in the TCCS, non-conforming products must be processed before being transferred to the next stage.

Raw material mines are also surveyed and explored to determine the quality of each raw material area, from which a mining plan is established and the raw materials will be mixed appropriately to ensure requirements and save resources. Similarly, the source of raw materials and fuel purchased from outside also ensures that only batches that meet quality requirements are allowed to be imported, and defective batches will be processed or returned to the supplier.

Marked in many major projects

Mr. Ton That Tung Thanh shared that the outstanding point in the quality control work at Dong Lam Cement Factory is the modern analytical equipment and technology application used. In order to promptly serve the quality control and assurance work, in addition to the standard analytical methods performed by a team of skilled laboratory workers, the Laboratory of Testing - Quality Assurance and Testing Services is also equipped with advanced testing equipment. Thermo Fisher Scientific's X-ray analyzer uses X-ray fluorescence (XRF) and X-ray diffraction (XRD) methods, which can accurately analyze chemical composition in less than 2 minutes, helping to control quality quickly and promptly.

In particular, Dong Lam is the first and only cement factory in Vietnam equipped with 2 Geoscan-C systems from Scantech (Australia) using the method of gamma-ray neutron instantaneous activation analysis (PGNAA - Prompt Gamma Neutron Activation Analysis), the results of online analysis (analysis of chemical composition of raw materials while being transported on the conveyor belt) of raw limestone imported into the warehouse and the mixture of raw materials for powder production will be transmitted to the computer located at the functional units every 30 seconds, including instantaneous values ​​and accumulated statistical data.

To ensure the accuracy of testing results and objectivity in product quality assessment, the Department of Testing - Quality Assurance & Testing periodically participates in proficiency testing programs, inter-laboratory comparisons with competent laboratories nationwide and periodically sends product samples to analysis centers such as the Center for Technical Standards and Quality Measurement 2 (Quatest 2), SGS Vietnam, Institute of Construction Materials, Quacert, etc.

In addition to manufacturing products that meet the requirements of technical standards and regulations with outstanding quality, Dong Lam also cares and tries to best satisfy the needs of users regarding the application properties of the products. At the factory, concrete mixtures and concrete are continuously tested by the product quality control team during the production process. Through application experiments, timely adjustments to technical indicators are made. Therefore, Dong Lam cement products are highly appreciated by users for their strength, plasticity, workability, cohesion and color preferences.

Dong Lam products have made their mark in many large projects and key works in the Central and Central Highlands regions such as Cu Mong Pass Tunnel, Hai Van 2 Tunnel, Deo Ca Tunnel, Da Nang International Airport Terminal, Alin Hydropower Plant, Thuy Yen Reservoir, Lien Chieu Seaport, My Thuy Seaport, Khe Sanh Wind Power Project, Da Nang Coastal Dike, VinCom Hue, Aeon Mall Hue, etc.
