In the golden autumn and August, the outdoor sun is like a fire; under the Yuelu Mountain, indoor heroes gather together!

 

On August 27-28, 2020, the Hunan Provincial Building Materials Standardization Technical Committee and the Hunan Institute of Ceramics jointly held the "Hunan Provincial Cement Concrete New Standard Promotion and the First Admixtures and Aggregate Application Technology Exchange Conference", It is the first technical exchange meeting in many years that integrates the industrial chain of cement, concrete, aggregate and admixtures. The conference highlighted the problem orientation, closely combined with the actual situation of the industry, and aimed at the hotspots, difficulties and focal issues of the industry development, as well as publicizing and implementing the recently released new standards for general cement, concrete, admixtures and sand and gravel aggregates. Luminescence, Liu Chen, Zhang Xiaofu were invited , Huang Zhengyu, Liu Juanhong, Li Chen and many other well-known experts respectively made 13 special technical reports. A special salon event was held on the afternoon of the 28th, with nearly 100 expert representatives participating, and the atmosphere for questions and discussions was enthusiastic. The conference materials are compiled and interpreted with a total of 1.3 million words, and the conference is rich in content. It provides a high-level technical communication platform for departments and personnel engaged in the research, production, and application of cement, concrete, admixtures and other industries. There are more than 300 representatives participating in the conference. Technological progress will play a positive role.

In recent years, concrete technology and production and operation formats have undergone great changes, such as changes in the quality of cement varieties, large-scale use of machine-made sand and gravel, substantial increase in raw material costs, a large number of related standards revisions, and the improvement of concrete performance requirements and quality disputes. Technical and managerial personnel in the industry are faced with many puzzles and challenges in terms of the integration and development of the concrete industry, the adaptability of raw materials and admixtures, and the quality of machine-made sandstones. The conference was held in the above context to summarize and exchange technical experience, and to explore solutions and measures.

 

The special technical reports of the conference include: Interpretation of T/CECS10087-2020 "Mixed Portland Cement" and proprietary technical solutions for the legal and compliant production of mixed cement (Chief Engineer, Building Materials Research Institute, China Academy of Building Research, Secretary of National Concrete Standardization Technical Committee Chang Leng Luguang researcher), publicizing new standards such as GB175 "General Portland Cement" (Deputy Secretary-General of National Cement Standardization Technical Committee, Deputy Director of Cement Standards Research Institute of China Building Materials Research Institute Liu Chen Gaogong), concrete water reduction The development history and trend of cement technology (Dr. Zhang Xiaofu, Vice President of Redwall New Material R&D), several issues in the application of admixtures in concrete (Professor Huang Zhengyu, School of Civil Engineering, Hunan University), and the promotion of the industrial chain level to promote the high-quality development of the cement industry (China Dr. Li Chen, Deputy Secretary-General of the Cement Association), Innovative technology of sand and gravel aggregates and thinking on concrete (Professor Liu Juanhong, University of Science and Technology Beijing)), Chemical admixtures for improving the durability of concrete and their technological progress (Bian Rongbing, Director of R&D, Redwall New Materials) , Concrete and its raw material industry policies and prospects (Ding Meirong, vice chairman of the Hunan Ceramic Society), standardization policies and corporate standardization practices (Liu Hong, deputy director of the Standardization Division of Hunan Market Supervision Administration), Hunan Ready-Mixed Mortar Development status and policy orientation (Chen Xiangquan, deputy director of the Provincial Bulk Cement Office and Wall Material Reform Office), current concrete and sandstone quality problems and countermeasures (Song Xiao, secretary general of the Provincial Building Material Standards Committee), interpretation of ``Premixed Concrete in Hunan Province Quality Management Implementation Rules and standards such as GB50164, GB/T14902, GB50204 (Deputy Chairman of the Provincial Building Materials Standards Committee Si Bingyan), interpretation of green building materials evaluation related documents and GB/T25181-2019 ``Ready-mixed Mortar'' and other new standards ( Huang Zhongwei, deputy chairman of the Provincial Building Material Standards Committee, Zhang Yanzhi, deputy director of Hunan Building Material Quality Supervision and Inspection Station).
