| 摘要： | The theme of this issue of PCI Journal is "Materials." This Research Corner presents an overview of the work that led up to the recently completed PCI specially funded research on ultra-high-performance concrete (UHPC). Additives to concrete mixtures to improve workability, as well as to maintain high early strengths while limiting water demand, have been researched for decades. Fly ash was the subject of a study published in 19901 that showed benefits that have prompted widespread use within the industry ever since. Studies were later done in specific product applications where the density of the cementitious matrix was augmented by adding silica fume, thereby increasing strength and resistance to chloride and moisture penetration. |
