Abstract:As a new type of composite material, the cement blanket has been applied in various engineering fields because of its simple and convenient advantages. On the basis of summing up the research and application of cement blanket, the properties of cement blanket are expounded. Combined with the practical case of the slope protection for Jinan - Qingdao Expressway, the construction technology of cement blanket in the slope of protection of expressway is discussed. The best practice of cement blanket formed in the aspects of overlap anchoring, spraying technology, etc. is worthy of reference. The practice shows that the cement blanket is an excellent slope protection material and is worth popularizing.
