11. Combination of Kaolin

Binding property refers to the combination of kaolin and non-plastic raw materials to form plastic sludge with a certain drying strength. Standard quartz sand is added to kaolin (70% of the total grain size is 0.25-0.15 and 30% of the total grain size is 0.15-0.09mm). It can be judged by the maximum sand content of plastic clay and the flexural strength after drying. The more sand is added, the stronger the bonding ability of this kind of kaolin is. Usually, kaolin with strong plasticity has strong bonding ability.。
