preparation example Construction

[0017] The preparation process of the concrete with excellent performance includes the following steps:

[0018] S1. Ingredients: first mix cement, sand, stone, water, paper tendons, straw, hemp knife and polypropylene fiber according to the weight ratio to obtain a mixture;

[0019] S2. Modified material: the polysulfone resin and poly[(2-oxiranyl)-1,2-cyclohexanediol]2-ethyl-2-( (Hydroxymethyl)-1,3-propanediol ether, SJ-101 resin, polyphenol aldehyde, and zinc trimer acrylate are mixed according to the weight ratio. After stirring for 4-6min, the temperature is rapidly increased to 85-92℃, and the modification time is stirred It takes 15-30 minutes to prepare modified materials;

[0020] S3. Stirring: adding the mixture prepared in step S1 to parts by weight of water, stirring for 8-10 minutes, adding the modified material prepared in step S2, and then stirring for 10-15 minutes to obtain concrete with excellent performance.

Abstract

The invention discloses a preparation process of concrete with excellent performance and the concrete thereof, belonging to the technical field of concrete preparation. The concrete with excellent performance comprises the following raw materials in parts by weight: 140 parts of cement, 28 parts of sand, and 25 parts of stone 350 parts of water, 18 parts of paper tendon, 22 parts of rice straw, 15 parts of hemp knife, 12 parts of polypropylene fiber, 6 parts of polyphenol aldehyde, 18 parts of polysulfone resin, poly[(2‑ethylene oxide group)‑ 8 parts of 1,2-cyclohexanediol] 2-ethyl-2-(hydroxymethyl)-1,3-propylene glycol ether, 10 parts of SJ-101 resin, 5 parts of zinc trimer acrylate, the construction concrete It is made through the steps of batching, modifying materials, stirring and so on. The concrete prepared by the invention has high tensile strength and compressive strength, and excellent toughness and anti-corrosion performance.

Description

【Technical Field】 [0001] The invention belongs to the technical field of concrete preparation, and specifically relates to a preparation process of concrete with excellent performance and concrete thereof. 【Background technique】 [0002] Concrete is a collective term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by mixing cement, gravel and fine sand as aggregates, mixed with water in a certain proportion, and admixtures and admixtures. Called ordinary concrete, it is widely used in civil engineering. [0003] Most of the existing concrete is made of simple cement, gravel, and fine sand mixed water. The surface of the concrete produced in this way is prone to cracks, has low tensile strength, poor corrosion resistance, and poor toughness. For example, the Chinese patent application document "High Toughness Concrete Formula" (Publication No.: ...
