为了挖掘水泥混凝土的潜力,改善其物理、化学性能,提高抗压、抗拉、抗折强度,国内许多混凝土科技工作者已采取不同的技术途径,寻求提高水泥混凝土强度的工艺方法和制备技术,并取行了较大的进展和较好的实验结果。其中,有的已经开始在工厂生产上或施工现场上推广应用。近几年来,报刊杂志上发表了许多有关高强混凝土的制备技术,现作为读书拾零,归纳整理如下: 一、高温高压蒸汽养护这种方法主要是使水泥石的化学反应由
In order to tap the potential of cement concrete, improve its physical and chemical properties, and improve its compressive strength, tensile strength and flexural strength, many domestic concrete technicians have taken different technical approaches to seek technical methods and preparation techniques for improving the strength of cement concrete. And took great progress and better experimental results. Among them, some have begun to promote the application of the factory or the construction site. In recent years, newspapers and magazines have published many techniques for the preparation of high-strength concrete, which are now used as reading books and summarized as follows: 1. High-temperature and high-pressure steam curing This method is mainly to make the cementite chemical reaction
