Problems solved by technology

[0002] The bridge piers in bridge projects in rivers, lakes, coastal areas and desert Gobi areas are generally made of reinforced concrete as the main structural material in the same way as the infrastructure in inland areas. There are continuous water erosion, flying sand erosion, and even ship contact and collision, which make ordinary concrete materials prone to serious wear and tear after forming the main structure for a period of time, and thus cannot ensure long-term protection in such an environment. Lower the service life of reinforced concrete structures, bringing hidden dangers to the safety and stability of infrastructure

Embodiment 1

[0028] An iron ore-based special concrete disclosed in the present application includes the components shown in Table 1 in parts by weight. Among them, the iron ore coarse aggregate adopts continuous gradation, and the particle size range is 6-20mm; the ceramic fine aggregate adopts continuous gradation, and the particle size range is 1-5mm; the solid content of the water reducing agent used is 20%, and its water reduction rate is greater than 30%.

[0029] The preparation method of this kind of iron ore special concrete comprises the following steps:

[0030] S1: Put cement, fly ash, mineral powder, silica fume, magnetic powder, ceramic fine aggregate, part of water, and water reducing agent into the concrete mixer for mixing to obtain mortar;

[0031] S2: put the iron ore coarse aggregate and part of the water into the concrete mixer for mixing, and obtain the iron ore coarse aggregate after antirust treatment;

[0032] Wherein, the process of performing S1 specifically in...

Embodiment 2-7

[0036] The difference from Example 1 is that the parts by weight of each component included are different, and the specific values ​​are shown in Table 1.

Abstract

The invention discloses iron ore special concrete and a preparation method thereof. The invention discloses iron ore special concrete, belongs to the technical field of concrete preparation, and solves the problem that the wear resistance of conventional concrete in the prior art cannot meet the use requirements of special environments The iron ore special concrete is characterized by comprising the following components in parts by weight: 900 to 1160 parts of iron ore coarse aggregate, 600 to 780 parts of ceramic fine aggregate; 135 to 165 parts of water; 310 to 380 parts of cement; 230 to 285 parts of a mineral admixture; and 8.5 to 10.2 parts of a water reducing agent. According to the technical scheme, the iron ore has stronger wear resistance and strength; the strength and the wear resistance of the concrete can be effectively improved when the concrete is used as main aggregate of the concrete; the surface area of the ceramic fine aggregate is larger, the ceramic fine aggregate is more strongly combined with a cementing material, and the ceramic fine aggregate is distributed in gaps of the coarse aggregate, so that the ceramic fine aggregate is more tightly bonded with the iron ore coarse aggregate by virtue of the cementing material, and finally, the concrete has better stability and wear resistance.

Description

technical field [0001] The present application relates to the technical field of concrete preparation, in particular to an iron ore-based special concrete and a preparation method thereof. Background technique [0002] The bridge piers in bridge projects in rivers, lakes, coastal areas and desert Gobi areas are generally made of reinforced concrete as the main structural material in the same way as the infrastructure in inland areas. There are continuous water erosion, flying sand erosion, and even ship contact and collision, which make ordinary concrete materials prone to serious wear and tear after forming the main structure for a period of time, and thus cannot ensure long-term protection in such an environment. Reduce the service life of reinforced concrete structures and bring hidden dangers to the safety and stability of infrastructure. Contents of the invention [0003] In order to realize that concrete materials have stronger stability and wear resistance when for...
