Abstract

The invention discloses anti-freezing concrete for a water conservancy project, and particularly relates to the technical field of concrete, and the anti-freezing concrete comprises the following mainmaterials in parts by weight: 10-15 parts of water; 14-18 parts of Portland cement; 0.5-1 part of a water reducing agent; 50-60 parts of limestone macadam; and 10-12 parts of medium sand. According to the invention, the concrete is stirred; water-based ethylene glycol is added into an aqueous solution; after concrete molding, the anti-freezing effect can be achieved on the concrete; meanwhile, the water-based ethylene glycol has an anti-corrosion effect, can prevent the concrete from being corroded by the environment, and prolongs the service life of the concrete; and waste textile fibers added into the raw materials of the concrete to increase the toughness of the concrete in synthesis, thus improving the compression resistance of the concrete, and the longer fibers of the concrete improve the plasticity of the concrete and facilitate the processing of the concrete.

Description

technical field [0001] The invention relates to the technical field of concrete, and more specifically, the invention relates to a frost-resistant concrete for hydraulic engineering. Background technique [0002] Concrete refers to the general designation of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to cement as cementitious material, sand and stone as aggregates; water (with or without addition) Admixtures and admixtures) are mixed in a certain proportion, and the cement concrete obtained by mixing, forming and curing is also called ordinary concrete, which is widely used in civil engineering. [0003] However, the frost-resistant concrete for water conservancy projects provided in the above technical solution, in actual use, the existing concrete is easily eroded by the external environment, such as temperature, weather, etc., which will cause damage to the concrete and affect its ser...
