Problems solved by technology

[0003] However, due to various operational problems in the construction process, it is easy to make the bonding force between the cushion layer and the surface layer on the ground weak, so that the bonding interface between the cushion layer and the surface layer is easy to separate, and the ground is easy to use during use. The hollowing phenomenon occurs due to the separation of the cushion and the surface layer, and the compressive strength of the ground is easily affected, making the ground easy to crack when it is hit by heavy objects. Therefore, there is still room for improvement

Embodiment 1

[0081] A cement floor construction method includes the following steps:

[0082] S1, grassroots treatment, as follows:

[0083] First, clean the dust, scum, oil, and debris on the base layer, and use cement mortar or fine stone concrete to fill in the obvious recesses on the base layer to make the surface of the base layer level.

[0084] S2, wetting the base layer, as follows:

[0085] Sprinkle water on the base layer to moisten it the day before construction, and remove the accumulated water on the base layer in time.

[0086] S3, stucco cement paste layer, as follows:

[0087] Portland cement and water are mixed in a ratio of 1:0.4 to prepare plain cement slurry, and a layer of plain cement slurry is painted on the surface of the wet base in time to form a plain cement slurry layer.

[0088] S4. Lay fine stone concrete cushion, as follows:

[0089] While painting the plain cement slurry, pour fine stone concrete on the plain cement slurry layer to form a fine stone concrete cushion, smo...

Embodiment 2

[0109] The difference from Example 1 is:

[0110] The plain cement slurry in step S3 is mixed with Portland cement and water in a ratio of 1:0.43 to prepare plain cement slurry.

[0111] The laying thickness of the fine stone concrete cushion in step S4 is 4.5 cm.

[0112] In step S5, the laying thickness of the cement bonding layer is 7.5 cm.

[0113] The distance between adjacent gray cakes in step S6 is 1.8m.

[0114] The laying thickness of the surface layer in step S7 is 32.5 cm.

[0115] The curing and molding in step S11 are as follows:

[0116] After the third time of rubbing for 11 hours, cover the surface layer with a mulch and sprinkle water 3-4 times a day to keep the surface layer moist, control the curing temperature to 25°C-30°C, and control the curing time to 29 days.

Embodiment 3

[0118] The difference from Example 1 is:

[0119] The plain cement slurry in step S3 is mixed with Portland cement and water in a ratio of 1:0.45 to prepare plain cement slurry.

[0120] The laying thickness of the fine stone concrete cushion in step S4 is 5 cm.

[0121] In step S5, the laying thickness of the cement bonding layer is 10 cm.

[0122] In step S6, the distance between adjacent gray cakes is 2m.

[0123] The laying thickness of the surface layer in step S7 is 35 cm.

[0124] The curing and molding in step S11 are as follows:

[0125] After the third time of rubbing for 12 hours, cover the surface layer with a mulch and sprinkle water 3-4 times a day to keep the surface layer moist. The curing temperature is controlled to 25°C-30°C and the curing time is 30 days.

Abstract

The invention relates to the field of building construction, and provides a cement floor construction method. The cement floor construction method aims to solve the problem of easy cracking caused byhollowing of the ground and comprises the following steps of S1, base treatment; S2, base layer wetting; S3, clear water slurry layer plastering; S4, fine stone concrete cushion layer paving; S5, cement bonding layer paving; S6, ash cake paving; S7, surface layer paving; S8, first-time plastering and pressing; S9, second-time plastering and pressing; S10, third-time plastering and pressing; and S11, curing and forming. The clear water slurry layer is paved between a base layer and a cushion layer, and a cement bonding layer is poured between the cushion layer and a surface layer, so that the bonding force between the base layer and the cushion layer is enhanced, the bonding force between the cushion layer and the surface layer is also enhanced, the base layer and the cushion layer are lesseasy to separate, the cushion layer and the surface layer are less easy to separate, the phenomenon of ground hollowing does not occur easily in the using process, the pressure resistance of the ground can be enhanced, and the ground cannot easily crack when being knocked by heavy objects.

Description

Technical field [0001] The invention relates to the field of building construction, and more specifically, it relates to a cement floor construction method. Background technique [0002] Ground refers to the paving layer inside and around the building, and also refers to the paving layer on the floor surface. In many factories, garages and canteens, cement floors are generally used for construction convenience. [0003] However, due to various operational problems in the construction process, it is easy to make the bonding force between the cushion layer and the surface layer weak, so that the bonding interface between the cushion layer and the surface layer is easily separated, making the ground easy to use during use. The hollowing phenomenon occurs due to the separation of the cushion layer and the surface layer, which makes the compressive strength of the ground easily affected, and makes the ground easily cracked when hit by heavy objects. Therefore, there is still room for i...
