method of using MTOTOP 900 concrete hardener

In compliance with ACI 302-1 R-89 and ACI 201-2RR77, the presence of concrete with a proper mixing plan is required. The concrete producer must be sure that the ratio of water to cement, the amount of cement, and the flow rate are in accordance with the minimum standard and according to the following values:

• Cement (SRC or OPC): at least 320 kg per cubic meter
• Water to cement ratio: 0.5 max
• At least 0.4
• Slump: desirable 75 mm
• Strength: at least 31 N/mm2

Concrete should not have separation or water leakage, and it should not contain more than 3% of air. When we apply this product on concrete with microsilica, we must be careful with the application time. For the best performance, it is recommended to use water-reducing additives such as mtoplase or mtocrete in concrete. The concrete layers on which the MTOTOP 900 concrete hardener is applied must have a minimum thickness of 75 mm. After concreting, the surface of the concrete should be leveled using a bar and then vibrated.
Level the concrete surface with a wooden trowel to avoid excessive polishing. Fix surface leaks. (Do not use a sponge) Spray MTOTOP 900 concrete hardener on the sides of the executive parts (where the executive and expansion joints are found) to a width of approximately 80 mm. Spread them on the surface using a wooden trowel.
MTOTOP 900 concrete hardener is ideally applied to a surface that is neither too dry nor too wet. The ambient temperature is the main factor determining this time. Normally, at temperatures of 35 to 45 degrees Celsius, a time of 30 to 40 minutes after concreting is suggested. This period will be longer at temperatures below 35 degrees Celsius. With the help of a long stand that runs the length of the concrete block, spread the rod material by hand on the wet concrete surface. The implementation is done in two stages.

1. Sprinkle two-thirds of the required material on the concrete surface, making sure to spread it evenly.
2. Allow the applied material to absorb moisture from the surface, a solid dark color will be visible.
3. Using a wooden trowel, spread MTOTOP 900 concrete hardener on the surface to ensure that it is uniform with the original concrete surface.
4. Apply the rest of the materials and after the color of the materials has darkened, spread them on the surface again with a wooden trowel.
5. When the surface is hard enough to accept the weight of a person and only a small indentation appears in his footsteps, the MTOTOP 900 concrete hardener should
6. be completed using a butterfly trowel. A smooth and non-slip surface will be obtained, but you should not work too much on the surface.
7. If the final smoothing is done using a hand tool such as a metal trowel, this should be done before the concrete hardens for traffic.

Concrete hardening performance of MTOTOP 900

Processing should be started immediately after the last troweling. This can be done by covering the surface with plastic sheets or by using curing materials. It is recommended to use MTOCURE at the rate of one liter per 5 square meters. Get more recommendations about processing materials from Iran's concrete clinic experts because the choice of materials can vary according to possible subsequent work on the surface.

practical tips in using MTOTOP 900 concrete hardener

Dry spraying should not be done in direct sunlight or in hot winds. The above care prevents early clay drying at a depth of 5 to 10 mm on the surface of the material and prevents its peeling and separation from the moist concrete below. The above adverse event will show itself when troweling. Like other concrete surfaces, the processing or curing of concrete and its time after the execution of concrete surfaces is very important and fundamental and must be done quickly after execution.
Coatings of one color can also be applied on the finished surface of MTOTOP 900 concrete hardener, but before choosing them, you must pay attention to materials such as the type of processing, the shape of the surface texture, and other things. (with expert department) Please contact Iran concrete clinic technician for further guidance.

MTOTOP 900 concrete hardening coating surface

The amount of material used can be between 3 and 7 kg per square meter, but in most industrial cases, a coating of 5 kg per square meter is recommended. For more information, contact the Iran concrete clinic technical service office.
