Refractory cement - Chemical Security Watch

heat-resistant cement - will evaluate the characteristics of the material

This special refractory cement has not only positive but also negative qualities.The latter of course is not so much, but they are.Actually with negative aspects begin.The first of them - the price.Since this is a specialized cement, respectively, and its price is higher than normal.Of course, this is not a huge difference, but for large parties it is really noticeable.

Another minus - the chemical composition.It has no effect on the life, does not affect the environment in general, it is harmless, but in interaction with some elements known table all possible chemical reactions that adversely affect the properties of the cement.

turn to the positive side , and the first of them - resistance to high temperatures.Indeed, depending on the brand and type of such cement is capable of withstanding up to 2 million degrees Celsius, and a special mark, which is very difficult to find, and will stand 3.5 thousand.Agree, the rate is incredible.

second advantage - the viscosity.For all important for the construction process parameters (adhesion, ductility, etc.) is not inferior to the conventional cement.

Another plus - easy to prepare.No need to be a chemist to mix the water, cement and sand.Actually, this is all that is needed to produce a refractory solution for the home.

Refractory cement - ready to work

Deciding on the use of special cement, you need to make some preparatory work that will facilitate further construction process.The fact is that the heat-resistant cement does not like grease, dust, oil stains and grime.That is why the preparatory works include degreasing and complete cleaning of surfaces.

Fat can be rubbed away with solvent or alcohol, and have a huge number of special fluids.Dust is removed with a vacuum cleaner and a damp cloth, but if on the surface, for example on the bricks, there is black, then it is desirable to carefully sanded, removing 2 millimeters of the structure of the brick.This will ensure maximum heat-resistant surface.

you need from building tools: drill, mixer nozzle, perhaps - a concrete mixer, trowel and, in fact, everything.

Heat-resistant cement - how to handle it?

After the preparatory work necessary to start filling itself and application of cement to the surface.The first step is to dissolve the desired amount to us in strict accordance with the instructions. Heat-resistant cement is not forgiving, so do not hurry.The main thing - full compliance.Dissolve or mix a can be in a small trough, and in a concrete mixer.It all depends on the amount of work.

stir, take it and pour it on the surface, which are going to handle.With the help of a trowel or trowel smoothes cement, giving it a smooth surface.Be sure to check the accuracy of the via level.If

masonry using this type of cement must be applied in a 5 mm layer to the surface, and then install the brick and presses it tightly.Thus fits and the second row, now the truth with the help of a trowel solution is applied to the first row of bricks and always on the joints between two adjacent bricks.

main thing is not to leave voids and carefully pour cement all joints and other possible costs of construction.That's all follow these rules, and your high-temperature cement will serve you for decades.
