The invention discloses a measuring needle head and measuring method for the content of soft particles in coarse concrete aggregate, which relates to a measuring needle head and measuring method for the content of soft particles and aims to solve the problems of poor operability and great error existing in the measurement of the soft particle content. The measuring need head is composed of a connecting rod and a measuring head, wherein the measuring head is a cylinder, one end face of the measuring head is a concave spherical surface, the outer circumferential surface at the upper end of the connecting rod is provided with a thread, and the lower end of the connecting rod is fixedly connected with a plane end of the measuring head. The measuring method comprises the steps of installing themeasuring needle head on a chuck of a penetration resistance instrument, placing a supporting platform below, putting a coarse concrete particle on the supporting platform, and applying pressure to the coarse concrete particle. The content of the soft particles in the coarse concrete aggregate is measured by combining the penetration resistance instrument, it can be ensured that the applied pressure is controlled within a range of 0-1000N, the measurement process is simple, the single measuring time is short, and the measuring efficiency can be significantly improved. The measuring needle head and the measuring method can applicable to measuring the content of the soft particles in the coarse concrete aggregate.
