Concrete sealing and curing floor construction plan

What is the concrete construction plan for the concrete sealing and curing agent floor? First of all, we must understand what is a concrete sealing curing agent!

1.

Concrete sealing curing agent, commonly known as liquid curing agent, is composed of inorganic substances, chemically active substances and silicon and substances, and is a new generation of lithium-ion water-based products

The typical use places of concrete sealing curing agent include warehouses, factories, shopping malls, shops, schools, food processing plants and hospitals and other floors

2.

Through the effective penetration of 5mm, the concrete sealant chemically reacts with the calcium oxide in the concrete, moisture and the compounds produced during the hardening of the concrete to form a hydrated calcium silicate, commonly known as tobermorite glue

Third, the function of concrete sealing and curing floor

The concrete sealing curing agent can penetrate the concrete surface and integrate with the concrete matrix.

Fourth, the concrete sealing curing agent floor construction plan

Preparation before construction

1.

(1) The concrete label must reach C25, and the cement must be Portland cement or ordinary Portland cement produced by a regular manufacturer.
The concrete should not be mixed or mixed as much as possible (the amount of cement should be within 10% of Grade I fly ash) Fly ash

(2) The concrete at the base level should meet the requirements of the relevant current national regulations;

(3) The metal or non-metal wear-resistant floor meets the requirements of the specification, and it is cured by sprinkling water for 7 days
.

2.
Construction site requirements

(1) The indoor construction temperature should be above 5 degrees, and there is no clear water on the ground;

(2) The lighting conditions of the construction site should be sufficient (to meet the needs of night construction);

(3) The construction site shall not cross-arrange construction operations other than the floor;

(4) At the construction site, the contracting party shall provide a warehouse for materials, equipment and utensils;

(5) All unnecessary sundries and facilities in the construction site should be cleared in advance;

Perform the following treatments according to the original ground:

1) Use a professional degreasing detergent to clean up the oil on the base surface.
If the oil is serious, scrape off the oil on the surface first.

2) Scattered wood flocs absorb the oil stains that seep into the base surface

3) Clean with detergent and steel brush

4) For some that penetrates the base surface and cannot be sucked out with wood wool, use a fire gun to bake

5) Clean the oily dirt from baking with detergent

6) Repeat this until it is cleaned

2.
The company's commonly used chemicals, organic solvents or water-based cleaning agents are designed to clean the surface of the surface oil stains.
The effect is also the most basic and economical degreaser;

3.
For heavy oil contaminated ground, the better effect is a carburetor, an organic solvent with strong decontamination ability, which has excellent cleaning ability in removing heavy oil, coal tar, and degreasing; it can penetrate into the interior of grease and other contaminants, Dissolve quickly and make it fall off
.
Excellent cleaning effect, fast volatilization, simple and convenient operation
.
It is an efficient, environmentally friendly, energy-saving solvent-based cleaning agent with a wide range of applications, no peculiar smell, no harm during use, and environmental protection and safety
.
It can eliminate the environmental damage caused by the use of chlorine and sulfur cleaning agents in the past
.
Can penetrate deep into the oily area of ​​1-5mm on the surface of the ground;

4.
If the above two solutions do not work, use heavy oil cleaning agent (solvent type), which is a national high-tech product, which can effectively penetrate into the base layer on marble, grindstone, and wear-resistant floors, so that the oil is reflected, and the interior of the oil is damaged.
Grease tissue, so that the oil stains inside the ground can be filtered up, wipe it with a dry cloth, and repeat it;

(The above scheme is subject to experiment)

3.
Material preparation

Concrete sealing curing agent

4.
Construction equipment

Multifunctional floor scrubber, vacuum cleaner, tape measure, two-meter ruler, bucket, row brush, sprinkling pot, leather hose, power cord

5.
Construction staff settings

1 site manager, 1 construction team leader, 1 safety officer, and several construction workers

6.
Construction schedule

Arrange reasonably according to the project schedule

Five, construction technology

1.
Construction process flow

1.
Clean up oil stains and scum on the base surface
.

2.
Spray the concrete sealing curing agent K01 on the treated base surface, and smear it evenly with a mop to ensure that the ground is sufficiently moist
.
If the water evaporates and becomes viscous, it should be diluted with water to make it fully penetrate the ground
.

3.
Wash the ground 1-2 times with a washing machine.
After 3-4 hours, clean the ground and scrape (or suck) the surface water
.

4.
After the ground surface is dry, spray the concrete sealing curing agent K02 on the ground and spread it evenly with a mop to ensure that the ground is sufficiently moist
.
If the water volatilizes and the ground turns white or crystallizes, sprinkle the diluted concrete sealing curing agent material to dissolve it and fully penetrate the ground
.

5.
During the 3-4 hours of soaking the ground in K02, use No.
300, No.
500, No.
800, No.
1500, No.
2000 to wash the ground 1-2 times, then clean the ground, and scrape (or suck) the surface
.

6.
It can be used three days after polishing
.

Six, ground maintenance instructions

1.
Do not coat the surface with wax or other sealants;

2.
Clean frequently
.
Water speeds up the reaction, promotes sealing of the ground and creates gloss
.
Use a black fiber gasket or brush head mounted on the automatic washing machine to wash, can speed up the appearance of light
.
(It is recommended to clean 2 to 3 times a week)

3.
Cleaning with detergent with high PH value (acid cleaning agent will destroy the appearance of the surface);

4.
Wash the spills as soon as possible, because the acid concentrate will permanently corrode the ground, and foods such as mustard oil, grape juice, etc.
, if not removed as soon as possible, may leave marks on the ground;

5.
Keep a good oil decomposer on hand to clean oil stains or ester stains, etc.
;

6.
Generally mild damage (within a depth of 5 mm) only affects the appearance, does not affect the use, and the local accidental damage will not spread to other places; if there is a large area of ​​damage, the damaged part can be cut and removed with a cutting machine, and then restarted.
Pouring concrete and applying concrete sealing curing agent;

7.
If you need to repair the cracks, you need to use a cutting machine to widen the cracks to one centimeter or more, repair with repair mortar, and then grind to the same level as the ground
.
If the repair material is a cement-based product, the concrete sealing curing agent needs to be reapplied; to repair a smaller pothole, it needs to be expanded to the extent that the diameter and depth are greater than one centimeter before repairing
.
