近年来灌浆方法的应用范围正在进一步扩大,灌浆技术正在完善,并且采用优化工艺。特别是广泛采用了《干式》方法,因为大部分指标——成品强度、各种条件的适应性、工艺性能都比《湿式》方法优异得多,湿法的优点只限于减少混凝土的剥落和涂抹时产生灰尘。在调制喷涂混凝土时,一般采用符合使用条件的各种水泥作为胶结料。例如欲获得 In recent years, the application range of the grouting method is being further expanded, the grouting technology is being improved, and the optimization process has been adopted. In particular, the “dry” method has been widely adopted because most of the indicators—finished product strength, adaptability to various conditions, and process performance are much better than the “wet” method. The advantages of the wet method are limited to the reduction of concrete flaking and Dust on application. In the preparation of sprayed concrete, various cements that meet the conditions of use are generally used as binders. For example, to obtain
