Preparation of the solution of clay for masonry stove - the proportions and components

stove or fireplace, until recently, been associated as a constant attribute of country house, but fortunately, again, they are now becoming popular.For good-quality furnace is not unimportant details, everything is important: the design, type of brick, quality solution for masonry.Good liquor composition must be close to the brick, to withstand repeated heating to 1000 degrees, not crack as time passes, and the seam formed with such a solution should ideally be 3-4 mm.

solution components

solution for a laying of the furnace consists of sand, clay and water.But these simple components must meet certain requirements.The main indicators of quality of solution - its texture and richness.And if the consistency of all is relatively simple - it should be like thick cream, the fat content is dependent on the quality of the clay, the ratio of sand and clay in solution, and are constantly checked in the preparation of the solution.The quality of the clay, or fat, affects the area where it is mined, and the depth.Some clay does not require the addition of sand, others take it anymore.Check the fat content in several ways.

The easiest way to check the clay and the solution is ready to dazzle the ball from the material and throw it on the floor with 1-1.5 meters.If the ball was not injured, or get a smooth cake, a good solution if the cake covered with cracks or even crumbled, then the solution over sand or clay is not enough fat.

For a more precise checking the clay is kneaded sufficiently cool and thoroughly kneaded.Then rolled the ball 4-5 cm in diameter and compress it gently between two smooth planks as long as there will be cracks.If the ball fell to pieces, even with little crushing, the clay is generally not suitable for solution for masonry oven.

If the crack went after compression by 20-25%, the clay or the solution is not enough, too fatty.The most suitable clay cracked when the ball is compressed by a third over the same fat provides compression fracture after more than half of the diameter.

too "lean" clay is not suitable for the preparation of the solution, as it dries and cracks will crumble.Needless fat solution is also not necessary, as there may be a large shrinkage at its furnace operation.

water have to be fresh and clean, better than tap.On average, in the preparation of a solution for a laying of hundreds of bricks consumes 15-20 liters of water, that is a quarter or a third of a bucket on a bucket of clay.

There are recipes using the salt or cement, but high-quality clay, these additives are unnecessary.If in doubt, and want to increase the strength of the masonry, it can be added to 10 kg of clay 100 grams of salt and 1 kg of cement.

with masonry with clay mortar easier to work with compared to the cement, it is possible to repeatedly disassemble and remake.In preparing the solution, keep in mind that the folding hundreds of bricks takes about three of his buckets.

sequence cooking

solution required to operate a wide shallow container (preferably metal and hard), shovel, smooth and durable plate for mixing, a sieve with 1,5 × 1,5 mm, facilitate the work of a drill with an attachment tostirring.

lumpy clay need to pre-soak for a couple of day in the vessel.Then, using shovels and feet (if a large volume) carefully to break all the lumps.Hands should always check to see whether the left has not crumbled pieces, stones and other debris.In

too fat clay is necessary to add sand, pre-screened through a sieve.It may be necessary from 0.5 to several volumes of clay, sand to pour the best part, thoroughly stirring and checking the quality of the solution after each batch.In most cases it is necessary to add the same amount of sand or slightly greater than the clay.

If quality clay and dry, you can immediately mix it with sand, and then add water.Stirring the solution so much easier, and it is a more homogeneous.

Ready solution is kept a day or two in a tightly closed container, and mixed immediately before every operation.It is worth noting that it is better to spend more time on a careful sifting of sand and clay before preparation of the solution, but then, at the time of laying, do not be distracted by removing stones and other impurities.
