干硬性混凝土是混凝土工程中的一种新技术,是随着装配式和预应力钢筋混凝土结构的预制构件的发展而产生的。在我国建筑业中,1955年已开始应用。由于干硬性混凝土拌合物可以节约水泥,在水泥材料供应紧张的情况下,它的使用就显得日益重要。不过,在推广中,由于对干硬性混凝土的特点认识不足,确实也发生了很多质量事故。但是,无论如何,干硬性混凝土是一种先进技术,它能推动建筑业走向工厂化、机械化生产。因此,我们对干硬性混凝土必须作进一步的研究,以期更好的利用它来节药水泥材料和保证工程质量。
Dry hard concrete is a new technology in concrete engineering, which is produced with the prefabricated components of prefabricated and prestressed reinforced concrete structures. In China’s construction industry, 1955 has begun to apply. As dry-hard concrete mixes save on cement, its use is becoming increasingly important as cement supplies become tight. However, in the promotion, due to lack of understanding of the characteristics of dry hard concrete, indeed, there have been a lot of quality accidents. However, in any case, dry hard concrete is an advanced technology, it can promote the construction industry to factory, mechanized production. Therefore, we must further study the dry and hard concrete, in order to make better use of it to save the cement material and ensure the quality of the project.
