| description | The invention relates to a nano-kaolin early strength agent with early strength and thickening functions. The nano-kaolin early strength agent is obtained by mixing and ball-milling kaolin, water, a grinding-aid dissolution promoter and a suspension stabilizer. The nano-kaolin early strength agent with the early strength and thickening functions can improve the early strength of concrete, increase the consistency of the concrete, prevent the prepared concrete from segregation and bleeding and reduce the porosity of the concrete; and when 1-4% of nano-kaolin is added, the 16h compressive strength of cement mortar can be improved by 50% at most, and the fluidity can be reduced by 23% at most. The preparation process is efficient, simple and low in energy consumption, does not cause pollution to the environment, provides a new way for high value-added utilization of kaolin, and is suitable for large-scale production.
