Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of ground is without levelling composition of sand and preparation method thereof
And construction method.
Background technique
Floor leveling refers to the original ground of building, levelling by certain method, and ground flat degree is made to reach one
Fixed standard meets regulation of the country about floor leveling.Floor leveling can be divided into two kinds, first is that original cement mortar
Face is levelling, second is that levelling with self-leveling material.Common cement mortar screeding has biggish defect, one side flatness control
System cannot accomplish maximum accurate, and levelling thickness is high, be on the other hand exactly construction technology it is easy due to construction party the technical issues of
House earth surface is caused to increase.Self-leveling material can be divided into inorganic system and organic system two major classes by main substrate difference.Inorganic system is certainly
Levelling material is primarily referred to as cement base and gypsum-based self-leveling material, and organic system self-leveling material refers mainly to epoxy self-leveling material
Material.But cement mortar has been easy ash, difficult cleaning, not acid-alkali-corrosive-resisting, so cement-based self-leveling material has been difficult to meet
Modern construction condition；The water-fast and wear resistence of gypsum is poor, surface strength is low, it is impossible to be used in the basement of balcony, roofing and humidity
Ground, while because being in neutrality or acid, there is the harm of corrosion to ironware, therefore, application is also restricted.
Therefore, in the prior art, tradition is levelling needs a large amount of cement river sands, and there are loads again, process is more, cost of labor
The drawbacks such as height, poor flatness, easy to crack.
Summary of the invention
It, should it is an object of the present invention in view of the deficiencies of the prior art, providing a kind of ground without the levelling composition of sand
Ground need not increase sand without the levelling composition of sand, and load of floor amount is effectively reduced, and effectively save river sand coyoting denudation environment is existing
Shape, and cost of labor can be reduced, so that construction is more convenient, material cost is less expensive, and has flatness good and not easy to crack
Advantage.
The second object of the present invention is to provide a kind of system of the ground without the levelling composition of sand in view of the deficiencies of the prior art
Preparation Method.
The third object of the present invention is in view of the deficiencies of the prior art, to provide a kind of ground applying without the levelling composition of sand
Work method.
One of to achieve the goals above, the present invention adopts the following technical scheme:
A kind of ground is provided without the levelling composition of sand, it is made of following parts by weight raw material:
Wherein, the component A is made of following parts by weight raw material:

It anticipates two or more compositions.
To achieve the goals above two, the present invention adopts the following technical scheme:
A kind of preparation method of the ground without the levelling composition of sand is provided, it the following steps are included:
Step 1: adding water in mixing plant: the water of formula ratio being added into mixing plant；
Step 2: component A foaming is added: the component A of formula ratio being added into the mixing plant of step 1, is then sent out
Steep certain time；
Step 3: portland cement is added: the portland cement of formula ratio being added in the mixing plant of step 2, so
After be stirred, obtain slurry shape mixture；
B component is added in step 4: the B component of formula ratio is added into the slurry shape mixture of the mixing plant of step 3,
Then certain time is stirred, obtains the ground without the levelling composition of sand.
In above-mentioned technical proposal, in the step 2, the component A of formula ratio is added into the mixing plant of step 1, so
After carry out foaming 30s~50s.
In above-mentioned technical proposal, in the step 4, it is added and matches into the slurry shape mixture of the mixing plant of step 3
Then the B component just measured stirs 2min~5min, obtains the ground without the levelling composition of sand.
To achieve the goals above three, the present invention adopts the following technical scheme:
A kind of construction method of the ground without the levelling composition of sand is provided, it the following steps are included:
The ground is put into after cast-in-place floor specified altitude assignment without the levelling composition of sand and is smeared using the levelling bar of aluminum by the first step
It is flat；
Second step is carried out after the ground can be trampled without the surface initial set certain time of the levelling composition of sand using grey knife
Artificial surface receives light processing, and to enhance surface smoothness and surface strength, then the ground is pre-hardening again without the levelling composition of sand
Certain time, subsequent paving floor tile or timber floor construction can be carried out by then carrying out wet water-wet profit screed-coat maintenance certain time.
In above-mentioned technical proposal, after the ground can trample for 8 hours~12 hours without the surface initial set of the levelling composition of sand,
Artificial surface is carried out using grey knife and receives light processing, and to enhance surface smoothness and surface strength, then the ground is levelling without sand
Composition is 12 hours~36 hours pre-hardening again, and subsequent paving can be carried out in 3 days~7 days by then carrying out wet water-wet profit screed-coat maintenance
Floor tile or timber floor construction.
Compared with prior art, beneficial effect is the present invention:
