GB/T 8075—2005 This standard revises the naming and definition of concrete admixtures (87—1A7). Compared with B/T5-187, it makes two changes: naming and defining new varieties of admixtures and mineral admixtures; adding the terminology of admixtures, and dividing it into two parts: basic terminology and performance specification; adding the naming of admixtures and the Chinese version of the reference. This standard is published by the China Building Materials Industry Association. This standard is issued by the National Water Conservancy Commission. The standardization technical committee of this standard is responsible for the unified management of the standard. The responsible units for the production of this standard are: Shandong Institute of Building Materials Science and Technology, Shandong Institute of Building Science, Building Materials Industry Technology Supervision, Shandong Laili Chemical Co., Ltd., Suzhou Concrete Water Products Research Institute, the drafters of the standard are: Niu Du, Tu Xue, Zhao Yang, Bei Zha, the Ministry of Education, Mei Yanle, Deng Jiang, Dang Jie, Tai Standards entrusted China Media Finance Institute to issue this standard. The first release time of this standard is 158? What is this standard? This is the first revision. 1. Definition, classification, nomenclature and terminology of concrete admixtures CB/T8075-2005. This standard specifies the classification, nomenclature and terminology of concrete admixtures. In addition, water-repellent and sand admixtures can also be used in this standard.
2. Definition
Concrete admixtures are materials added before or during the concrete coagulation process to improve the quality of concrete (or harden concrete). They are hereinafter referred to as admixtures. 3. Classification ||tt ||1 Additives can be divided into the following categories according to their main uses:
3.1 Additives that change the properties of concrete with temperature, including various admixtures that reduce water content, etc.: 3.2 Additives that regulate the setting time and hardening properties of concrete, including retarder, light accelerator and other admixtures; 3.3 Additives that improve the durability of concrete, including degassing agents, rust inhibitors and other additives; 3. Additives that improve other properties, including antifreeze agents, antifreeze agents, etc. 1 Naming
