Example Embodiment

[0018] The specific implementation of the invention will be described in further detail below in conjunction with specific examples.

[0019] A concrete of this embodiment is composed of the following components in the following mass percentages: 8.02% cement, 8.02% admixture, 45.50% coarse aggregate, 30.71% fine aggregate, 7.30% water and 0.45 % Of additives;

[0020] The cement is in powder state, and the main mineral component is: tricalcium silicate 3CaO·SiO 2 , Dicalcium silicate 2CaO·SiO 2 , Tricalcium Aluminate 3CaO·Al 2 O 3 , Tetracalcium Aluminate 4CaO·Al 2 O 3 ·Fe 2 O 3 And 5% calcium sulfate;

[0021] The composite admixture for concrete is commonly called ultrafine powder, and its main mineral components are: CaO, SiO 2 , AlO 3 , MgO and Fe 2 O 3 ; Among them: CaO, SiO 2 And AlO 3 Accounted for more than 90%.

[0022] The coarse aggregate is a stone, which acts as a skeleton in the concrete.

[0023] The fine aggregate is river sand, which acts as a skeleton in the concrete...

Abstract

The invention discloses concrete and a making method thereof. The concrete consists of the following components in percentage by mass: 8.02% of cement, 8.02% of an admixture, 45.50% of coarse aggregate, 30.71% of fine aggregate, 7.30% of water and 0.45% of an additive. The making method comprises the following steps: firstly, weighing the coarse aggregate, the fine aggregate and the water within an error less than or equal to 2.0%; feeding the weighed cement, the admixture, the fine aggregate, the water and the additive into a stirrer, stirring for 50 seconds at a speed of 45r/minute, feeding the coarse aggregate, that is, pebbles, into the stirrer, and stirring for 50 seconds; and pouring out the stirred concrete. By adopting the making method, the concrete can be completely uniformly stirred, the early strength of the concrete is ensured, and continuous growth of later strength of the concrete is also ensured.

Description

technical field [0001] The invention relates to the technical field of concrete, and relates to concrete and a preparation method thereof. Background technique [0002] Due to the influence of external environment such as weather and temperature, the existing commonly used concrete formulations are prone to cracking, grout leakage, freezing, segregation, etc., which seriously affect the concrete. Concrete itself is relatively strict in the selection of various raw materials. The mud content and strength of sand and stone all affect concrete. If the chloride ion content in various raw materials is too large, it is extremely easy to cause internal corrosion of concrete. After the concrete is set, it cannot be reused or recycled, and can only be treated as garbage. Contents of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the purpose of the present invention is to provide a concrete and its preparation method, which can promote th...
