摘　　要：花岗岩作为是一种酸性深成火成岩,其母岩强度高脆性大,加工后的碎石压碎值大、针片状偏多,经过试验脆性花岗岩碎石已成功应用在C60高性能混凝土中,为今后脆性花岗岩碎石的运用提供借鉴。The granite achievement is one acidity becomes the igneous rock deeply, mother rock intensity high brittleness is big ,the squash value is big, the needle laminated shape are many, has succeeded the application after the experiment in the C60 high performance concretes, will provide for the present uses for reference.
