摘要
2005年4月，一项针对美国和加拿大波特兰水泥和混合水泥生产商的调查收集了2004年生产水泥的数据。感兴趣的特性包括满足ASTM C 150, C 595和C 1157规范所需的特性:物理测量，如强度和细度，化学成分和性能特性，如凝固时间。本文总结了所收集的数据，并对硅酸盐水泥和混合水泥的结果进行了比较和对比。还介绍了波特兰水泥特性的历史数据，并指出了趋势或缺乏趋势。总的来说，数据表明波特兰水泥的特性在过去10年中相对没有变化。
Characteristics of portland and blended cements: results of a survey of manufacturers
In April 2005, a survey of manufacturers of portland and blended cements in the US and Canada was conducted to collect data on cements produced in 2004. The characteristics of interest include those required to meet specifications ASTM C 150, C 595, and C 1157: physical measurements such as strength and fineness, chemical composition, and performance characteristics such as setting time. This paper summarizes the data collected, comparing and contrasting results on portland and blended cements. Historical data on portland cement characteristics are also presented and trends, or the lack thereof, are noted. Generally, the data indicate that portland cement characteristics are relatively unchanged over the last 10 years.
