On May 23, 2024, the Vietnam Institute of Building Materials (VIBM) held a meeting to review and accept several basic-level research tasks. The meeting was chaired by the Vice Presidents: Mr. Nguyen Van Huynh, Mrs. Luu Thi Hong, and Mr. Vu Van Dung. The attendees included Mr. Cao Tien Phu, Head of the Planning & Technical Department; Mrs. Trinh Thi Cham, Deputy Head of the Planning & Technical Department; and Directors and Deputy Directors of various specialized centers.
At the meeting, MSc. Nguyen Van Minh (Center for Ceramics and Glass) presented an overview of the task titled "Survey and Evaluation of Factors Affecting Flush Volume, Load Bearing Capacity, and Plastic Lid Durability of Toilet Bowls Using Specialized Equipment at the Institute of Building Materials," Project Code V01-23.
Following this, Dr. Kieu Le Hai (Center for Ceramics and Glass) reported on the task "Research to Determine the Solar Heat Gain Coefficient (SHGC) of High-Performance Building Glass Types and Assessing the Sustainability of Glass Use in Vietnam," Project Code V02-23. The objective of this task was to determine the SHGC of high-performance building glass types (energy-efficient glass) available in the domestic market and to propose solutions for sustainable glass use in construction in Vietnam.
Also during the meeting, MSc. Truong Duc Tiep (Center for Refractory and Fireproof Materials) represented the research team to report on the task "Research to Improve the Thermal Shock Resistance of Refractory Concrete Using Sintered Bauxite Aggregate," Project Code V03-23. The goal of this research was to improve the thermal shock resistance of refractory concrete by partially replacing sintered bauxite aggregate with silicon carbide (SiC). The results showed that replacing bauxite with SiC reduced the thermal expansion coefficient of the refractory concrete and significantly increased its thermal shock resistance. However, the amount of added SiC affects the bulk density and mechanical properties of the product. Under test conditions, a maximum of 15% SiC should be used to meet the product’s technical requirements.
On behalf of the research team, Eng. Le Tuan Anh (Center for Equipment, Environment, and Labour Safety) reported on the task "Research and Evaluation of Various Measurement Methods and Techniques Commonly Used to Determine Thermal Conductivity Coefficient of Building Materials," Project Code V04-23. The goal of this task was to review and test several types of thermal insulation materials in the laboratory, propose suitable materials for different devices and testing standards, and contribute to the training and development of VIBM’s staff to improve their skills and equipment utilization.
Eng. Ngo Tuan Dung (Center for Organic Materials and Construction Chemicals) presented on the task "Research to Enhance the Flame Retardancy of PVC (Polyvinyl Chloride) Materials According to the Difficult-to-Ignite (BC) Test of QCVN 06:2022/BXD," Project Code V05-23. The aim of this task was to select suitable flame retardants for PVC and improve the material’s flame retardancy to achieve BC2 level as per QCVN 06:2022/BXD.
Eng. Phan Văn Quỳnh (Center for Cement and Concrete) reported on the task "Research on the Effects of Dispersed Fiber Reinforcement (PP Fiber) on Rheological Properties, Mechanical Properties, Early Age Shrinkage, and Crack Resistance of Self-Consolidating Concrete," Project Code V06-23. The objective was to evaluate the effects of dispersed fibers on the rheological properties of the mixture and the mechanical properties of self-consolidating concrete, with the goal of mastering high-quality self-consolidating concrete technology for both civil and industrial construction projects.
After the presentations by the project leaders, the VIBM Scientific and Technological Council discussed, provided feedback, and agreed on the acceptance of the tasks, requesting the project teams to continue refining their reports based on the Council's comments.
