A mixture of refractory masonry - how to make fire safe ?

People variant mixture

Clay solution for furnaces - a mixture of refractory, which is based on the clay, and the filler is natural sand with a maximum grain 1.5 mm.It is very easy to use and yet has good processing properties.Used to masonry wood stoves and chimneys.

work do not recommend such material at a temperature below +5 degrees.Temperature brick and mortar should also be higher than +5.Bricks are used only dry, with moisture wicking properties.Masonry is from 10-13 mm seam or open seam to further fill it with a mixture.To carry out the work necessary to comply with all the rules of the masonry work and the requirements of the project.

After the end of five days the temperature should be maintained above 5 degrees.Use design can only 2-3 weeks after the complete drying of solution.During drying, all the dampers and valves must be open.The first heating is carried out carefully, for example, you can simply blow the warm air.The next five days is a weak warming fire.

Important!During the warming up of all procedures and flap valves must be open.

modern solution for masonry masonry

Warm mix also provides refractory masonry mortar.This refractory mixture that consists of water glass and silica sand with a grain size of not more 0.5 mm.The mixture is very easy to use and has a high technical characteristics.It is used for masonry fireplaces and stoves indoors.

Just as clay mortar, refractory mix can not be used at temperatures below 5 degrees.Masonry made suture of 1-2 millimeters.Chemical seizure solution takes place at room temperature, and ceramic - at least 700 degrees.Before you can use the entire structure dried for 2-3 weeks with open valves and dampers.Warming up is the same as in the previous case.

Note!A feature of this solution is that strong and reliable setting occurs only at high temperatures.

Step by step, put the oven

Insulation masonry mixture should be used strictly for the use of standards.masonry technology is carried out in the following sequence:

  • Before starting work, all the bricks are soaked in water;
  • prepared mixture for masonry.For this purpose, one or two sacks mixture filled into the container.With constant stirring, slowly add the water.The consistency of the solution should be such that at the time of laying it under the weight of bricks and light touch hand appeared;
  • seam thickness should be 2-3 mm.The thinner is the seam, the clutch will be stronger.

After seam hardens, it tends to expand when heated to a degree equivalent to a refractory brick.This is due to the composition of the solution and helps to avoid cracks in the masonry during exploitation of furnaces and fireplaces.One bag of the mixture must be calculated by an average of forty-bricks.
