Description

technical field [0001] The invention relates to a preparation method of a concrete additive, in particular to a carbon nano additive for improving the comprehensive performance of cement concrete and a preparation method thereof, belonging to the field of building material additives. Background technique [0002] Due to the low cost of cement concrete production materials, and its high compressive strength and structural stability, it is widely used in domestic road construction. However, with the increasing domestic traffic volume, ordinary cement concrete pavement can no longer meet the requirements of traffic load. Especially under heavy load conditions, the cement concrete pavement is often damaged in advance due to various disasters before reaching the expected service life, causing incalculable losses to the normal operation of the road. Therefore, the development of functional additives is of great significance to improve the comprehensive performance of cement concr...
