With a selection and application of JQ-HPC80 mode mine shaft special high performance con-crete admixture ,a high strength and high performance concrete with a low quantity of cement and binding material was prepared and the strength of the concrete could be over 90MPa and could fully meet the construction requirements of the mine shaft liner in the present coal mines. The paper stressed an introduction on different raw material and performance index applied to the preparation of the high strength and high performances concrete ,mixing ratio design and working performances ,me-chanics performance test condition.
