近几年,人造轻骨料在建筑业逐渐得以应用,但由于我国对于粘土的烧胀性能及烧胀机理尚未形成统一认识,没有定型的陶粒厂工艺设计方案,因而各地兴建的陶粒厂生产工艺极不一致,产品质量和性能也不稳定。有的陶粒生产线,用优质粘土能够烧制出轻质陶粒,但用劣质粘土(砂土、碱土)则烧不出合格产品。任邱地区的粘土含砂量大,属碱性劣质粘土,是否具有烧胀性能?可不可以焙烧出轻质高强的陶粒来?为此,我们做了大量的调查、试验、研究工作,对粘土陶粒的烧胀机理进行
In recent years, man-made lightweight aggregates have gradually been used in the construction industry. However, due to the fact that China has not formed a unified understanding of the properties of the clay’s swellability and the mechanism of swell and expansion, and there is no stereotyped ceramsite process design scheme, the ceramic factories built around the country have not been established. The production process is extremely inconsistent and the product quality and performance are also unstable. Some ceramsite production lines can produce lightweight ceramsites from high-quality clay, but inferior clays (sand-earth, alkaline-earth) cannot produce qualified products. Is there clay in the Renqiu area with large amounts of sand, is it a basic poor quality clay, does it have bulk expansion properties, can it be calcined to produce light, high-strength ceramsite? For this reason, we have done a lot of investigations, experiments, and research work. The sintering and expansion mechanism of clay ceram
