Description

Technical Field

[0001] The present invention relates to the technical field of permeable concrete, and in particular to a highly frost-resistant permeable concrete and a preparation process and application thereof. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] With the emergence of urban heat island effects and urban waterlogging, sponge city construction has become widespread. Permeable concrete, a key foundational material for sponge city construction, is primarily composed of cementitious materials and coarse aggregate. It has a high number of interconnected and macropores, resulting in excellent water permeability, which promotes rainwater infiltration into the ground. Furthermore, during hot weather, moisture in the soil beneath the permeable concrete evaporates, reducing surface temperatures. This significantly reduces urban waterlogging and the heat island effect.

[0004] The coarse aggregate in permeable concrete is bonded together by cement binder. To ensure good permeability, the amount of cement binder used is relatively low. This results in a low coating thickness of cement binder on the aggregate surface. Furthermore, due to the low surface roughness of the aggregate, the bond strength between the hardened cement paste and the aggregate is low. In winter, during rainy and snowy weather, water enters the permeable concrete and freezes at relatively low temperatures. The resulting volume expansion can easily cause the coarse aggregate to separate from the hardened cement paste, leading to cracking in the permeable concrete, seriously shortening its service life. Summary of the Invention

[0005] To address the above-mentioned issues, the present invention provides a highly frost-resistant permeable concrete, its preparation process, and its application. By increasing the pore complexity and hydrophobicity of the hardened cement paste, this method inhibits the diffusion and transmission of water within the hardened paste, thereby improving the frost resistance of the permeable concrete and extending its service life. Specifically, the technical solution of the present invention is as follows.

[0006] First, the present invention discloses a highly frost-resistant permeable concrete, the raw materials of which include: 15 to 25 parts by weight of belite-sulfoaluminate cement, 60 to 70 parts by weight of aggregate, 5 to 10 parts by weight of ferroaluminate mineral admixture, 1 to 2 parts by weight of anhydrite, 0.3 to 0.5 parts by weight of polymer glue powder, 0.01 to 0.02 parts by weight of calcium stearate, 0.001 to 0.002 parts by weight of cerium oxide, and 8 to 12 parts by weight of mixing water.

[0007] Furthermore, the mass proportion of the belite mineral in the belite-sulphoaluminate cement is not less than 45%, and the crystal form is α' type.

[0008] Furthermore, the main mineral components of the aluminoferrite mineral admixture include C6AF2, C2F, and C2S, wherein the total mass proportion of C6AF2 and C2F is not less than 50%.

[0009] Furthermore, the polymer powder is a compound of polyacrylate powder and polyvinyl alcohol powder (PVA). Optionally, the mass ratio of the polyacrylate powder to the polyvinyl alcohol powder is 1:0.2-0.8.

[0010] Furthermore, the particle size of the aggregate is in the range of 6 to 10 mm.

[0011] Furthermore, the raw material composition also includes 0.1 to 0.2 parts by weight of a water reducer. Optionally, the water reducer includes any one of a polycarboxylate water reducer, a naphthalene water reducer, an aliphatic water reducer, and the like. In the present invention, the water reducer primarily reduces water consumption and lowers the porosity of the hardened slurry in the permeable concrete.

[0012] Furthermore, the raw material composition also includes 0.1 to 0.2 parts by weight of a defoamer. Optionally, the defoamer includes at least one of an organosilicon defoamer, a polyether defoamer, a polyether-modified silicon defoamer, and tributyl phosphate. In the present invention, the defoamer primarily functions to reduce macropores in the hardened cement paste.

[0013] Furthermore, the raw material composition also includes 0.05 to 0.1 parts by weight of a retarder. Optionally, the retarder includes at least one of tartaric acid, sodium citrate, glucose, etc. In the present invention, the main function of the retarder is to prevent the sulfoaluminate cement from setting and hardening too quickly.

[0014] Secondly, the present invention discloses a preparation process of highly frost-resistant permeable concrete, comprising the steps of:

[0015] (1) Add the polymer rubber powder, calcium stearate and cerium oxide into mixing water and mix them evenly to obtain a mixing slurry.

[0016] (2) The mixing slurry is mixed with Belite-sulfoaluminate cement, ferroaluminate mineral admixture, anhydrite, and aggregate, and the obtained slurry is formed and then cured to obtain frost-resistant permeable concrete.

[0017] Furthermore, the step (1) further comprises the step of adding at least one of a water reducing agent, a defoaming agent and a retarder to the mixing water.

[0018] Furthermore, the curing method in step (2) includes any one of standard curing, natural curing, etc.

[0019] Finally, the present invention discloses the application of the highly frost-resistant permeable concrete in the fields of municipal engineering, gardening, and ground parking lot construction.

[0020] Compared with the prior art, the technical solution of the present invention has at least the following beneficial effects:

[0021] The permeable concrete of the present invention incorporates aluminoferrate mineral admixtures and cerium oxide. This is because the C6AF2 and C2F in the aluminoferrate mineral admixtures have low hydration activity and cannot synchronize with the film formation of the polymer powder, thereby failing to form an interwoven structure. To this end, the present invention has discovered that cerium oxide can not only induce the C6AF2 and C2F to hydrate with the mixing water in advance, thereby improving the synchronization of film formation with the polymer powder, but also that the iron colloid (Fe(OH)3) formed by the hydration of C6AF2 and C2F under the induction of cerium oxide has a flaky structure rather than a clustered structure. This flaky iron colloid interweaves with the film formed by the polymer powder, significantly increasing the complexity of the pores in the hardened slurry. Not only are some pores blocked, but the transmission path of the pores is also longer. In addition, the calcium sulfonate formed by the reaction of aluminoferrate minerals with gypsum can not only reduce the shrinkage of the slurry, but also reduce the porosity of the cement hardened slurry in the permeable concrete. At the same time, the present invention utilizes the hydroxyl groups on the polymer powder film as anchoring points, anchoring the calcium stearate to the film formed by the polymer powder through the complexation of its calcium ions with the hydroxyl groups. This allows the calcium stearate to be evenly and firmly dispersed on the pore surfaces of the permeable concrete. Since the calcium stearate has excellent hydrophobic properties, it inhibits the diffusion and transmission of water in the hardened slurry, significantly improving the frost resistance of the permeable concrete and increasing its service life. Furthermore, the present invention utilizes a composite powder formed by polyacrylate powder and polyvinyl alcohol powder, which not only significantly increases the bond strength between the hardened cement slurry and the aggregate, but also exhibits excellent water resistance, thus imparting excellent water resistance to the permeable concrete of the present invention. During the later service life of the permeable concrete, the α'-type belite mineral has a high hydration activity, allowing for slow hydration in the later stages of hydration, preventing the permeable concrete from experiencing strength shrinkage.
