Corrosion-resistant and anti-seepage concrete material and preparation method thereof

Abstract

The application relates to the field of concrete materials, and specifically discloses a corrosion-resistant and anti-seepage concrete material and a preparation method thereof. Corrosion-resistant and anti-seepage concrete materials include the following raw materials in parts by weight: cement, water, fine sand, gravel, mineral admixture, magnesium oxide, nano-sulfur, hexamethyldisiloxane, octamethylcyclotetrasiloxane alkane, dodecamethylcyclohexasiloxane; its preparation method is 1) weigh the mineral admixture and magnesium oxide according to the corresponding weight parts, and mix them evenly to obtain the admixture component 1; 2) weigh the sulfur according to the corresponding weight and polysiloxane defoamer, mix uniformly to obtain the admixture component 2; 3) mix the admixture component 1, admixture component 2 and other raw materials evenly, and prepare the corrosion-resistant and anti-seepage concrete material . The corrosion-resistant and anti-seepage concrete material of the present application can make it difficult for water to penetrate into concrete pores, and has better corrosion resistance and anti-seepage performance.

Description

technical field [0001] The application relates to the field of concrete materials, more specifically, it relates to a corrosion-resistant and anti-seepage concrete material and a preparation method thereof. Background technique [0002] In construction projects such as underground structures and water storage structures of industrial and civil buildings, there are generally certain requirements for the corrosion resistance and impermeability of concrete. [0003] Ordinary concrete increases the compactness of concrete by improving the gradation and reduces the continuity of the pores in the internal structure of the concrete to improve the impermeability of the concrete. However, it is difficult to completely eliminate the pores in the internal structure of the concrete by improving the gradation. Sulfate or chlorine in the water Harmful ions such as salt can easily penetrate into the external pores of concrete to decompose the hydration products of concrete, causing the por...

[0003] Ordinary concrete increases the compactness of concrete by improving the gradation and reduces the continuity of the pores in the internal structure of the concrete to improve the impermeability of the concrete. However, it is difficult to completely eliminate the pores in the internal structure of the concrete by improving the gradation. Sulfate or chlorine in the water Harmful ions such as salt can easily penetrate into the external pores of the concrete to decompose the hydration products of the concrete, causing the pores of the concrete to be destroyed and connected from the outside to the inside, resulting in a gradual decrease in the impermeability of the concrete and a decrease in the strength of the concrete.

[0004] Based on the above prior art, the inventor believes that the existing concrete has external moisture that easily penetrates into the pores of the concrete, which easily causes corrosion problems to the internal structure of the concrete, and affects the impermeability and durability of the concrete
