Abstract

The invention provides a high-strength waterproof concrete. The concrete comprises the following components in parts by weight: 100-120 parts of cement, 80-85 parts of coarse aggregate, 90-100 parts of fine aggregate, 20-25 parts of bentonite, 20-25 parts of asphalt powder, 2-5 parts of alkyl sodium sulfonate, 2-3 parts of copper sulfate, 10-12 parts of basalt fiber, 5-8 parts of polypropylene fiber, 2-3 parts of Grace fiber, 0.2-0.5 part of sodium perfluorooctylsulfonate, 0.1-0.2 part of coconut oil diethanolamide, 0.5-1 part of bisphenol A epoxy resin, 0.1-0.2 part of styrylphenol polyoxyethylene ether, 3-5 parts of iron chloride, 0.2-0.5 part of phenyl salicylate, 2-5 parts of aluminum potassium sulfate, 0.1-0.2 part of 1,6-hexamethylene diisocyanate and a right amount of water. The invention also discloses a method for preparing the concrete. According to the invention, the concrete has favorable impermeability, and the maximum impermeability pressure can be up to 9.8 MPa; and the obtained concrete has high compression strength, and the maximum compression strength can be up to 112 MPa.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a high-strength waterproof concrete. Background technique [0002] When carrying out large-scale civil engineering construction in humid and rainy areas or underwater, the water resistance of concrete is one of the most important inspection indicators. At present, the impermeability pressure of ordinary waterproof concrete is 0.6MPa, and the highest impermeability of better waterproof concrete is between 3.0-5.0MPa. However, for engineering requirements with a compressive strength greater than 20MPa, many concretes currently on the market are not suitable. Some improved waterproof concrete can only meet the engineering construction requirements of 40-50MPa. [0003] Therefore, for large-scale projects that require higher strength, it is still necessary to find suitable waterproof concrete. Contents of the invention [0004] In view of the shortcomings of the pri...
