前言波特兰水泥在室温下与水反应,生成一种固态物质。这一反应称为水化反应,反应时生成新的粘结矿物与一定量的水化石灰。无论从强度、化学性或耐久性来看,水化石灰通常被认为是波特兰水泥浆中最弱的部分。因此,水泥和混凝土工艺师们的一项持久性研究工作就是打算把这种石灰转变为更稳定的更强的组分。两千年以前,罗曼斯发现,当他们把在庞贝(Pompeii)附近普特阿里(Puteoli) Introduction Portland cement reacts with water at room temperature to form a solid substance. This reaction is called hydration reaction, the reaction generates a new bond minerals and a certain amount of hydrated lime. Hydrated lime is generally considered the weakest part of Portland grout, whether it is strength, chemical or durability. As a result, a persistent research effort by cement and concrete technologists aims to transform this lime into a more stable and stronger constituent. Two thousand years ago, Romans found that when they put Puteoli near Pompeii,
