偏高岭土 meaning in Chinese
metakaolin
Examples
- 2 ) the concept of mineral functional material is put forward , it discusses the manufacture technology of mineral functional materials with industrial waste , especially research on the feasibility of hpc ' s functional material by meta - kaolin
( 2 )提出了矿物功能材料的概念，探讨了以工业废料为基料的矿物功能材料的制备技术，特别研究了偏高岭土作为高性能混凝土功能材料的可行性。 - It focuses on the theory of the mineral functional materials " improving the anti - chloride permeability and the chloride binding . the main achievements of this article include : 1 ) use the technology of xrd , sem , bet , laser particle size distributor etc to test the component , the construction , particle size distributor , specific surface etc of micro - silica , ultra - fined slag , high quality fly ash , meta - kaolin clay , four types of the mineral functional material , theoretically analysis the functions which the four mineral functional minerals act on cement concrete , namely pozzolanicity effect , filling effect , micro - aggregate effect , surface adsorption effect and so bring into play the affect of plastification , lowing of temperature , reinforcement , improvement of durability . base on this analysis we can conclude that the proper diameter of the mineral functional material is 5 m - 15 m , that is blain fineness 4500cm2 / g - 7500cm2 / g
本论文的主要成果包括以下几个方面： ( 1 )采用xrd 、 sem 、 bet 、激光粒度分析仪等多种测试手段，探明了以硅灰，超细磨粒化高炉矿渣，优质粉煤灰及偏高岭土超细粉等4种超细矿物功能材料的组成、结构、粒度分布、比表面积等基本性质；从理论上分析了矿物功能材料在混凝土中的4种效应，即火山灰效应、填充密实效应、微集料效应、表面吸附效应，并由此发挥出增塑、温峰削减(降热) ，增强及耐久性改善等作用；通过相关理论分析，推导出矿物功能材料的合理粒径范围在5 m 15 m ，即勃氏比表面积为4500cm ~ 2 g 7500cm ~ 2 g 。 - Proper amount of micro - silica , ultra - fined slag , high quality fly ash , meta - kaolin clay can improve the working ability , hydration heat and strength ( especially in the later period ) of the cement concrete . proper amount of meta - kaolin clay can do good to the strength of the cement concrete but verse to the working ability by magnifying water - cement ratio
适量硅灰、优质粉煤灰、矿渣超细粉的加入，改善了混凝土的工作性、水化热及强度(特别是后期强度) ；适量偏高岭土对水泥混凝土强度产生有利影响，但对工作性会有一些不利影响，主要是加大水胶比。
