Abstract

The invention relates to the technical field of concrete. The concrete for road construction is prepared from the following materials in parts by weight: 40 to 60 parts of cement; 30 to 40 parts of sand; 20 to 30 parts of mineral powder; 50 to 67 parts of stone; 18 to 32 parts of water; 1 to 3 parts of plant fiber; 0.5 to 2 parts of a water reducing agent; and 2.5 to 4 parts of montmorillonite. The concrete provided by the invention has the advantages of excellent compression resistance and high splitting strength.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to concrete for road construction and a preparation method thereof. Background technique [0002] Concrete pavement refers to the pavement with cement concrete slab as the surface layer. It refers to the pavement structure composed of cement concrete slab as the surface layer, base layer and cushion layer, also known as rigid pavement. [0003] Although the existing road concrete has the advantages of high compressive strength, easy material acquisition, easy molding, and low price, its compressive strength and splitting strength need to be improved. [0004] In order to solve the above problems, this application proposes a concrete for road construction and a preparation method thereof. Contents of the invention [0005] (1) Purpose of the invention [0006] In order to solve the technical problems existing in the background technology, the present invention proposes a concret...
