Embodiment 1

[0042] The strengthened hollow brick of the present embodiment comprises the raw material of following mass fraction: Prepare the raw material of following mass: described cement is 25 parts, and sand is 150 parts, and water is 20 parts, and metal chip is 0.8 part, and wherein: cement can adopt No. 325 ordinary Portland cement, the sand is medium sand, medium sand refers to the sand whose particle size is greater than 0.25mm and the mass of the particles exceeds 50% of the total mass, and the mud content in the sand does not exceed 5%. The amount of mortar is low, and the strength of the mortar configured is higher. The length of the metal chips is 5-20mm. Steel is the most commonly used material in the processing and manufacturing industry. Therefore, the metal chips in this embodiment mainly include iron filings. Of course, not all iron chips Chips can be used. Due to the high carbon content and high brittleness of cast iron, the chips produced by turning, milling, planing, g...

Embodiment 2

[0053] The strengthened hollow brick of the present embodiment comprises the raw material of following mass fraction: Prepare the raw material of following quality: described cement is 25 parts, and sand is 150 parts, and water is 20 parts, and metal chip is 1 part, and wherein: cement can adopt No. 325 ordinary Portland cement, the sand is medium sand, medium sand refers to the sand whose particle size is greater than 0.25mm and the mass of the particles exceeds 50% of the total mass, and the mud content in the sand does not exceed 5%. The metal cuttings The length is 5-20mm, steel is the most commonly used material in the processing and manufacturing industry, so the metal chips in this embodiment mainly include iron filings, of course not all iron filings can be used, because cast iron has a high carbon content Chips produced during processing such as cutting, milling, planing, and grinding are broken chips, which are not within the scope of use.

Embodiment 3

[0064] The reinforced hollow brick of the present embodiment comprises the following mass fractions of raw materials: prepare the following mass of raw materials: 25 parts of the cement, 150 parts of the sand, 20 parts of the water, and 1.2 parts of the metal swarf, wherein: the cement can be No. 325 ordinary Portland cement, the sand is medium sand, medium sand refers to the sand whose particle size is greater than 0.25mm and the mass of the particles exceeds 50% of the total mass, and the mud content in the sand does not exceed 5%. The metal cuttings The length is 5-20mm, steel is the most commonly used material in the processing and manufacturing industry, so the metal chips in this embodiment mainly include iron filings, of course not all iron filings can be used, because cast iron has a high carbon content Chips produced in processes such as cutting, milling, planing, and grinding are broken chips, which are not within the scope of use.

Abstract

The invention discloses a reinforced concrete hollow brick. The reinforced concrete hollow brick comprises the following raw materials in parts by mass: 20-30 parts of cement; 120 to 180 parts of sand; 10 to 30 parts of water; and 0.8 to 1.2 parts of metal chips. The invention also relates to a preparation method of the reinforced concrete hollow brick. The method comprises the following steps: S1, the following raw material in parts by mass: the 20-30 parts of cement; 120 to 180 parts of sand; 10 to 30 parts of water and 0.8 to 1.2 parts of metal chips are prepared; s2, the metal cuttings aresubjected to breaking treatment, so that the length range of the metal cuttings is within 5-20 mm; s3, the metal chips are subjected to degreasing treatment; and S4, the cement, sand, the metal chipsand water are fully stirred and then conveyed into a mold, and the mixture is compacted and fired into bricks. According to the concrete hollow brick, the metal chips are added, the metal chips are uniformly distributed in the concrete hollow brick in a physical form, and a compressive strength test shows that the compressive strength of the concrete hollow brick added with the metal chips is obviously improved.

Description

technical field [0001] The invention relates to the technical field of brick body manufacture, in particular to a reinforced concrete hollow brick and a preparation method thereof. Background technique [0002] In the machinery industry, a large amount of swarf is often generated during the metal processing and forming process, but most domestic factories do not pay enough attention to the aspect of swarf disposal, and the swarf is piled up in the open air and thrown seriously. The chips are large and fluffy, contain a lot of oil, and are easy to pollute the environment, which is the main source of pollution in the factory. Chip handling is an unavoidable and difficult problem. [0003] In the construction industry, hollow bricks are the main wall materials commonly used at present. Compared with solid bricks, they can save a lot of land, soil and fuel for burning bricks, and reduce transportation weight; reduce the weight of buildings and reduce construction costs; , soun...
