Abstract

Non-sintered cement (NSC) mortar was developed using only industrial by-products, such as ground granulated blast furnace slag, classes C and F fly ashes, and slaked lime. The characteristics of different NSC mortar formulations were investigated, as well as their applicability for use in forming precast concrete products. X-ray diffraction and scanning electron microscope analyses were performed to examine the internal structure of the different formulations. Overall, the developed NSC mortar satisfied the existing quality standards in terms of strength performance and absorption rate. Therefore, it is expected to be highly applicable as a raw material for production of the desired cement products.

通过蒸汽养护研究非烧结水泥砂浆在预制混凝土中的适用性

无烧结水泥（NSC）砂浆的开发仅使用了工业副产品，如磨细高炉矿渣、C 级和 F 级粉煤灰以及消石灰。研究了不同 NSC 砂浆配方的特性，以及它们在成型预制混凝土产品中的适用性。对不同配方的内部结构进行了 X 射线衍射和扫描电子显微镜分析。总体而言，所开发的 NSC 砂浆在强度性能和吸收率方面均符合现有的质量标准。因此，它有望成为生产所需的水泥产品的一种非常适用的原材料。
