Detailed Description
Referring to fig. 1 and 2, the present embodiment provides a micro-cement ground structure, which comprises, from inside to outside, an anti-crack layer 1, a hardened layer 2, an effect layer 3, a sealing layer 4 and a mask layer 5.
The micro-cement ground structure of the embodiment has high hardness, is scratch-resistant, wear-resistant, waterproof, skid-resistant, easy to clean, and wide in application range, can be applied to the ground formed by cement mortar, terrazzo, marble, ceramic tiles or gypsum, and can also be applied to the ground at indoor or room temperature.
The anti-cracking layer 1 is used as a bottom layer structure of the micro-cement ground structure and used for separating the ground substrate 6 from the hardened layer 2 and other structures so as to reduce water vapor, dust and the like from entering the interior of the micro-cement ground structure. In addition, the anti-cracking layer 1 can also strengthen the overall strength of the micro-cement ground structure, prevent the cracking of the hardened layer 2, the effect layer 3 and the like, and most importantly, prevent the cracking of the effect layer 3. Since the leveling layer of the ground substrate 6 is generally soft and is easily deformed when being stressed, the embodiment separates the ground substrate from other layers of the micro-cement ground structure through the anti-cracking layer 1, and improves the cracking phenomenon of the effect layer 3 through the hardness of the anti-cracking layer 1.
Specifically, the crack prevention layer 1 includes a glass fiber net 11 and a primer. The glass fiber net 11 is laid on the ground substrate 6 and used for supporting the hardened layer 2 and improving the bonding effect of the hardened layer 2; the primer is coated on the glass fiber mesh 11 and the ground substrate 6 and is used for isolating the ground substrate 6 from the hardened layer 2 and sealing other structures of the micro-cement ground structure. In addition, the primer can adhere the glass fiber net 11 to the ground substrate 6 due to the certain viscosity of the primer, so that the glass fiber net 11 is prevented from being displaced.
Specifically, the using amount of the primer is 0.13-0.17 kg/m 2; exemplary are 0.13 kg/m2, 0.14 kg/m2, 0.15 kg/m2, 0.16 kg/m2, or 0.17 kg/m 2.
The thickness of the primer layer formed of the primer is determined by the amount of the primer, and if the amount of the primer is less than 0.13 kg/m2, the thickness of the primer layer formed is too thin, and the sealing effect is deteriorated. In other embodiments of the present application, the amount of the primer may be greater than 0.17 kg/m2, but this increases the cost of the micro-cement floor structure, and the sealing effect cannot be further improved, and the sealing effect is already the best when the amount of the primer is 0.17 kg/m 2.
The hardened layer 2 is coated on the crack-resistant layer 1 for increasing the hardness of the micro-cement ground structure and facilitating the formation of the effect layer 3. Specifically, the hardened layer 2 is made of coarse and fine cement. Wherein, the coarse and fine cement comprises coarse sand and fine cement, and compared with medium sand and fine sand, the coarse sand has high hardness and low cost.
In this example, the mass ratio of coarse sand to micro cement in coarse micro cement was 16:4. If the consumption of coarse sand is too small and the consumption of micro cement is too large, the consistency of the mixture is low, the construction difficulty is increased, the curing time is long, and the flatness of the hardened layer 2 is reduced; furthermore, the cost of the micro-cement is higher than the cost of the coarse sand, thus increasing the overall cost of the surface micro-cement structure.
If the dosage of the coarse sand is too much and the dosage of the micro cement is too little, the consistency of the mixture is higher, the mixture is difficult to extend and tile, and the construction difficulty is increased; more importantly, the hardness of the formed hardened layer 2 is reduced, and the construction requirements are not met.
In other embodiments of the present application, the mass ratio of coarse sand to micro-cement in the coarse micro-cement may also be 16:3.8, 16:3.9, 16:4.1, or 16: 4.2.
Specifically, the dosage of the coarse and micro cement is 1.33-1.67 kg/m 2; exemplary are 1.33 kg/m2, 1.4 kg/m2, 1.45 kg/m2, 1.5 kg/m2, 1.55 kg/m2, 1.6 kg/m2, or 1.67 kg/m 2.
The thickness of the hardened layer 2 formed from coarse and fine cement is determined by the amount of coarse and fine cement used, and if the amount of coarse and fine cement used is less than 1.33 kg/m2, the thickness of the coarse and fine cement formed is too thin and the hardness is insufficient. In other embodiments of the present application, the amount of coarse micro-cement may be greater than 1.67 kg/m2, but this increases the cost of the micro-cement floor structure.
The effect layer 3 is covered on the hardening layer 2, and is a structure which is visually displayed to the customer in the micro-cement ground structure of the embodiment, that is, the micro-cement ground structure seen by the customer is the effect layer 3. In addition, the effect layer 3 has high hardness, and is scratch-resistant, wear-resistant and anti-skid.
Specifically, the effect layer 3 is made of fine cement or medium-fine cement. Wherein the medium and micro cement comprises medium sand and micro cement, and the fine cement comprises fine sand and micro cement.
Specifically, fine cement or medium-fine cement is selected according to the requirements of customers, the surface structure of the effect layer 3 made of the medium-fine cement is rough, and the surface structure of the effect layer 3 made of the fine cement is fine and compact.
Because the densities of the medium sand and the fine sand are different, the dosage proportion of the medium sand and the fine sand is also different. Specifically, the mass ratio of the medium sand to the micro cement in the medium micro cement is 16:4, and the mass ratio of the fine sand to the micro cement in the micro cement is 14.3: 5.7. That is, the amount of medium sand is more than that of fine sand.
If the consumption of the medium sand or the fine sand is too small and the consumption of the micro cement is too large, the consistency of the mixture is low, the construction difficulty is increased, the curing time is long, and the flatness of the surface layer is reduced; furthermore, the cost of micro-cement is higher than the cost of medium or fine sand, thus increasing the overall cost of the surface micro-cement structure.
If the dosage of the medium sand or the fine sand is too much and the dosage of the micro cement is too little, the consistency of the mixture is higher, the mixture is difficult to extend and tile, and the construction difficulty is increased; more importantly, the hardness of the formed surface layer is reduced, the construction requirement is not met, and the appearance is influenced.
In other embodiments of the present application, the mass ratio of the medium sand to the micro cement in the medium micro cement may also be 16:3.8, 16:3.9, 16:4.1, or 16: 4.2.
In other embodiments of the present application, the mass ratio of fine sand to micro-cement in the fine cement may also be 14.3:5.5, 14.3:5.6, 14.3:5.8, or 14.3: 5.9.
Specifically, the dosage of the medium and micro cement is 1.0-1.25 kg/m 2; exemplary are 1.0 kg/m2, 1.12 kg/m2, 1.15 kg/m2, 1.17 kg/m2, 1.20 kg/m2, 1.22 kg/m2, or 1.25kg/m 2. The thickness of the hardened layer 2 formed of the medium and micro cement is determined by the amount of the medium and micro cement, and if the amount of the medium and micro cement is less than 1.0 kg/m2, the thickness of the formed medium and micro cement is too thin and the hardness is insufficient. In other embodiments of the present application, the amount of medium micro cement may be greater than 1.25kg/m2, but this increases the cost of the micro cement floor structure.
Specifically, the dosage of the fine cement is 0.67-0.77 kg/m 2; exemplary are 0.67 kg/m2, 0.69 kg/m2, 0.70 kg/m2, 0.72 kg/m2, 0.74 kg/m2, 0.75 kg/m2, or 0.77 kg/m 2.
Similarly, if the amount of fine cement used is less than 0.67 kg/m2, the resulting fine cement will have an excessively thin thickness and insufficient hardness. In other embodiments of the present application, the amount of fine cement may be greater than 0.77 kg/m2, but this increases the cost of the fine cement floor structure.
In this embodiment, the classification of coarse sand, medium sand and fine sand is the same as that of the sand material in concrete, specifically, μ f =3.1 to 3.7 of coarse sand, the particle diameter is 0.5mm to 1.0mm, μ f =2.3 to 3.0 of medium sand, the particle diameter is 0.25mm to 0.5mm, μ f =1.6 to 2.2 of fine sand, and the particle diameter is 0.125mm to 0.25 mm.
The sealing layer 4 covers the effect layer 3, is of a transparent structure, isolates the air from the effect layer 3, and is used for sealing other structures of the micro-cement ground structure under the combined action of the anti-cracking layer 1 to play a good protection role.
Specifically, the sealing layer 4 is also made of primer, and the using amount of the primer is 0.13-0.17 kg/m 2; exemplary are 0.13 kg/m2, 0.14 kg/m2, 0.15 kg/m2, 0.16 kg/m2, or 0.17 kg/m 2.
The mask layer 5 is covered on the sealing layer 4 and has a transparent and smooth structure for protecting the sealing layer 4. Because the surface of sclerosis layer 2 and effect layer 3 is coarse structure, and the thickness of seal 4 is very thin again, can't become level and smooth with the surface of effect layer 3, can effectively improve little cement ground structure's waterproof anti-skidding effect behind the formation mask layer 5 on seal 4 to make little cement ground structure easily wash.
Specifically, the mask layer 5 is made of core-shell silicon emulsion, styrene-acrylic emulsion or hydroxypropyl emulsion. Wherein the dosage of the core-shell silicon emulsion, the styrene-acrylic emulsion or the hydroxypropyl emulsion is 0.13-0.17 kg/m 2; exemplary are 0.13 kg/m2, 0.14 kg/m2, 0.15 kg/m2, 0.16 kg/m2, or 0.17 kg/m 2.
It should be noted that, because the climates in the south and north are different, and the temperature and humidity in summer and winter are different, the constructor can select the dosage and the proportion of the primer, the coarse and micro cement, the medium and micro cement, the fine cement and the like according to the conditions and the climates of the site.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
