Abstract

The invention provides an oil corrosion-resistant agent for concrete, belonging to the field of building material preparation. The oil corrosion-resistant agent comprises organic silicon, water glass, an air entraining agent, polyol and water, wherein the addition amounts of the above components by weight percent are respectively 10-30%, 10-20%, 0-0.05%, 5-15% and 35-75%. According to the invention, when the oil corrosion-resistant agent for concrete is used in the concrete, the oil corrosion resistance and the durability of the concrete can be improved significantly. Tests show that when the oil corrosion-resistant agent accounting for 2-3% of the total weight of the concrete is added to the concrete, the oil-resistant penetration height ratio of the concrete can be increased by more than 35%, the oil absorption rate can be increased by more than 40%, and the compressive strength of the concrete at various ages can be increased by more than 16%.

Description

technical field [0001] The invention relates to an anti-oil erosion agent for high-strength concrete and a preparation method thereof. The invention belongs to the field of building material preparation. Background technique [0002] In the production process of machinery industry, the oil splashed out due to transmission, metal cutting and grinding, such as some mineral oil or vegetable oil, has the characteristics of low viscosity and strong penetration ability, which makes it very difficult to contact with concrete. It is easy to penetrate into concrete and destroy the bond between cement and aggregate in concrete. In addition, some oils penetrating into concrete will also contain some meta-acids or esters, which will damage the strength and durability of reinforced concrete components. [0003] For the above problems, the damage to concrete caused by the penetration of oil substances can be effectively solved by improving the oil resistance of concrete. Oil-resistant ...
