OLY-7201 self-leveling mortar construction method:

Mixing ratio: water powder = 1 4 (kg);

Pour water into the container, then add the self-leveling mortar in proportion, stir it with an electric mixer until there is a uniform slurry without agglomeration for about 3-5 minutes, let it stand and mature for about 2-3 minutes, and then stir briefly once to pour the material for construction;

The stirred self-leveling slurry is poured on the construction floor, it will flow and level the ground on its own, if the design thickness is 4mm, it needs to be scraped with the help of a special self-leveling tooth scraper.

Subsequently, the construction personnel should be allowed to put on special spikes, enter the construction ground, and gently roll on the self-leveling surface with a special self-leveling deflating roller to release the air mixed in the stirring to avoid bubbles and the height difference of the interface.

1. It has good fluidity, in the case of a few millimeters thick, it has good leveling, and the slurry has good stability, so that it can minimize the occurrence of undesirable phenomena such as segregation, delamination, water leakage, and foaming, and it is necessary to ensure that it has enough usable time, usually more than 40 minutes, so as to facilitate construction operation.

2. The flatness should be good, and there should be no obvious defects on the surface.

3. As a ground material, its physical and mechanical properties such as compressive strength, wear resistance, impact resistance, and water resistance should meet the requirements of general indoor building ground.

4. Good durability.

5. The construction is simple, fast, time-saving and labor-saving.

Self-leveling cement mortar is a type of floor that can provide a flat and smooth floor surface that can be laid with a final finish layer such as carpet, wood flooring, etc. The key performance requirements are fast hardening and low shrinkage. There are different ground systems available in the market, such as cement-based, gypsum-based, or a mixture of them.

Self-leveling cement mortar is a water-coagulated hard composite material made of cement as the base material and other modified materials through a high degree of compounding. Although the existing formulas are different and the formulas are different, the materials are generally inseparable from the types listed below, and the principle is roughly the same. It is mainly composed of the following six parts:

1) Mixed cementitious material, (2) mineral filler, (3) coagulant, (4) rheological modifier, (5) reinforcing component, (6) water composition.

The main technical properties of self-leveling cement mortar.

1) Fluidity.

Fluidity is an important indicator to reflect the performance of self-leveling cement mortar. The general fluidity is greater than 210 260mm.

2) Slurry stability.

This index is an index that reflects the stability of self-leveling cement mortar. Pour the mixed slurry onto a horizontally placed glass plate, 20

After a few minutes, there should be no obvious phenomena such as water secretion, stratification, segregation, and foaming. This index has a great impact on the surface condition and durability of the material after molding.

3) Compressive strength.

As a ground material, this index must meet the construction specifications of cement floor, and the domestic ordinary cement mortar surface layer ground requirements are 15MPa compressive strength

Above, the compressive strength of the cement concrete surface layer is 20MPa

Above. (4) Flexural strength.

The flexural strength of self-leveling cement mortar for industrial use should be greater than 6MPa.

5) Setting time.

The setting time of self-leveling cement mortar is determined to be evenly stirred to ensure that its use time is 40

minutes, operability is not affected.

6) Impact resistance.

Self-leveling cement mortar should be able to withstand the collision of the human body and the carrying items in normal traffic, and the impact resistance of the ground is greater than or equal to 4

Joule. (7) Abrasion resistance.

Self-leveling cement mortar, as a ground surface material, must withstand normal ground traffic. Due to its flow.

The flat layer is thinner, and in the case of a solid ground base, its bearing force is mainly on the surface, not in the volume. Therefore, its wear resistance is more important than compressive strength.

8) Tensile strength of the bond to the base layer.

The bonding strength of self-leveling cement mortar and the base layer is directly related to whether there will be hollowing and falling off after the slurry hardens, which has a great impact on the durability of the material. In the actual construction process, the ground interface agent is brushed to achieve a condition that is more suitable for the construction of self-leveling materials. The adhesive tensile strength of self-leveling materials for domestic cement floors is usually as follows.

Above. (9) Crack resistance.

Crack resistance is a key indicator of self-leveling cement mortar, and its size is related to whether cracks, hollowing, falling off and other phenomena occur after the self-leveling material is hardened. Whether the crack resistance of the self-leveling material can be correctly evaluated is related to whether the success or failure of the self-leveling material product can be correctly evaluated.

Whether cement self-leveling ground is good or not depends on the worker's process.

1. Clean the ground first, and then apply the interface agent, and the first time can be painted after the second time is dry, and the general time should wait until 2 to 4 hours. Note that the strength of the concrete must reach 15MPa. In addition, the concrete floor should not be loose or other debris.

If there are holes, repair them with mortar.

2. After ensuring that it is completely dry, the next step of construction can be carried out, the self-leveling cement is added to clean water and stirred evenly, and then stirred into a slurry with a mixer. This slurry is poured directly onto the ground and is generally 4 to 6 mm thick.

3. Before the initial setting, the workers put on spikes, walk into the ground, and then use tools to squeeze out all the bubbles on the surface.

4. Finally, do a good job of cement self-leveling maintenance, and it will take about a day to lay other ground materials, and pedestrians can be placed on it.

Precautions for self-leveling cement construction:

1. Before construction, the ground must be cleaned to ensure that the ground is dry, solid, dust-free, crack-free, oil-stained and other impurities. In addition, there should be no hollow drums on the ground, and the places where the drums are raised should be knocked off, the soft base should be reinforced first, and the potholes and cracks should be repaired first.

2. Be sure to pay attention to the environment during construction, if it is a dry ground, the temperature can generally not be lower than 10 degrees Celsius, and the humidity should be kept at 80% 90%. At the same time, there should be no strong wind indoors, so as to avoid too dryness. If it is a summer construction and the temperature is relatively high, you can choose to work at night.
