Semi-buried concrete for salinized soil area and preparation method thereof
The invention discloses a semi-buried concrete for a salinized soil area and a preparation method thereof. The semi-buried concrete is composed of 10-24% of cement, 55-80% of aggregate, 1-2% of nano mineral admixtures, 2-5% of polymer additive, 0.1-0.5% of adjuvant, 0.2-0.5% of nano-modifier, 2-5% of barium hydroxide microcapsule powder and 7-8% of water, wherein the aggregate consists of fine aggregate of which the particular size is 200 meshes and coarse aggregate of which the particular size is 5-20mm, the weight of the coarse aggregate of which the particular size is 5-20mm is greater than 43% of the total weight of the aggregate. When the concrete is prepared, the above raw materials are placed in a forced mixer in batches to uniformly stir and mix, therefore the uniformity of concrete can be ensured; furthermore, a polymer and a light nano-material are adopted, the good pavement performance can be realized, the sulfate corrosion resistance and the bittern corrosion resistance can be improved, and the frost-resistance of the concrete can be improved, therefore the semi-buried concrete has an important meaning on the development of the salinized soil regional economy and road transportation.
