采用捣固法施工的半湿状态的耐火混合料称为耐火捣打料。与耐火可塑料不同，此类耐火混合料是一种低塑性或无塑性捣固材料，是依靠强制捣固而形成致密体，再经加热烘烤或焙烧发生硬化而获得一定的结构强度。现在捣固法施工的材料，除可塑料 (湿式捣打料)和捣打料(半湿式捣打料)外，还有干式捣打料(不含液体的捣打料)，是一种完全无塑性捣打料。

过去耐火捣打料的材质与品种较多，使用范围较广，但由于捣打施工劳动强度大，施工作业时间长，难以获得均匀的整体衬体，已逐渐被其他施工方法的不定行耐火材料所取代。现在使用这种半湿式状态的捣打料场所不多。目前捣打料的主要品种有：铝 -镁质捣打料，高铝(或刚玉)-碳化硅-炭质捣打料，碱性耐火捣打料和锆莫来石质捣打料等。

The semi wet refractory mixture used in the construction of the tamping method is called the refractory ramming material. Unlike fire resistant plastic, such refractory mixture is a low plastic or non plastic stamp material, which is formed by compacting and compacting, and then obtained a certain structural strength after heating, baking or roasting. Now, materials for tamping construction include plastic (wet ramming) and ramming material (semi wet ramming), and dry ramming material (no liquid ramming material), which is a completely non plastic ramming material.

In the past, the materials and varieties of refractory ramming materials were more widely used, but due to the strong labor intensity and long operation time, it was difficult to get uniform overall lining, which has been gradually replaced by other construction methods. There are not many places to use this semi wet state of tamping materials. The main varieties of ramming materials are: Aluminum magnesia ramming, high aluminum (or corundum), silicon carbide carbon ramming, basic refractory and ramming.
