Abstract

The purpose of this study was to develop a standard reference material that can simulate the flow characteristics of cement paste. For this purpose, it is important to determine the constituent materials of the standard material for cement paste. Generally, cement paste is a mixture of cement and water. To determine the constituent material of cement paste, it was divided into powder that can replace cement and matrix fluid. With the concept of rheology, which can evaluate the flow properties of selected materials quantitatively under certain mixing conditions, experiments were carried out step-by-step according to material composition combination, stage of aging, and material types. As a result, limestone powder was determined to be a cement substitute, and glycerol and water were determined to be a matrix fluid substitute. After an analysis of the compatibility with the required properties of the particulate standard materials, the finally selected standard reference material was found to satisfy the required performance.

摘要

本研究的目的是开发一种能够模拟水泥浆体流动特性的标准参考材料。为此,确定水泥浆体标准材料的组成材料很重要。一般来说,水泥浆体是水泥和水的混合物。为了确定水泥浆体的组成材料,将其分为可替代水泥的粉末和基体流体。基于流变学的概念,即在特定混合条件下定量评估所选材料的流动特性,根据材料组成组合、老化阶段和材料类型逐步进行实验。结果,确定石灰石粉为水泥替代品,甘油和水为基体流体替代品。在分析与颗粒标准材料所需性能的兼容性后,发现最终选定的标准参考材料满足所需性能。
