Solutions

The solution was usually prepared in wooden boxes and 100X50X15 150X70X25 cm to fall asleep filler and binder, which are pre-screened by a sieve. For solutions used for plastering work, use the sieve with a cell 5 \ 5 mm stone - 10HYU mm.


Of clay and lime mortar is immediately ready, and of cement at first - dry weight, and the solution.

Solutions should be prepared carefully, stirring well and strictly observing the proportions of the composition of aggregates, binder and water. This guarantees a homogeneous composition solution, which is easier to fit than the non-uniform.

Clay solution was prepared as follows.

Pour the clay with water for a day or more, and then stir it until a creamy mass, which is filtered through a sieve with a cell of at least 3X3 mm. If the liquid clay, she is given to settle and drained the excess water. In the clay solution is added the sand and mix well. Number of added sand depends on the fat content of clay. To 1 part clay taken from 2 to 4 parts sand.

Water was added so much to get the desired solution density. These solutions are used for laying the overground parts of cottages and outbuildings in which the humidity inside the building will not exceed 60%. To increase the strength of the solution, you can add cement at the rate of 100 kg per 1 m3 of solution that will increase the compressive strength of up to 8 kg/cm3. Such a solution should be used within 1 -1.5 hours

Mortar made from lime paste with the addition of sifted sand and water, stirring until smooth. To avoid any lumps, strain the best solution through a sieve with a cell 10HYU mm.

Depending on the fat content of lime to 1 part of lime paste added from 2 to 5 parts sand. When added to a solution of 75-100 kg of cement per 1 m3 of mortar strength increases up to 8 kg/cm3.

Lime-clay mortar used for the same purpose as the limestone and clay. Value of lime, clay and sand in the solution is 1:0,3 / 0,4 /: 3 / 5. In the lime is added first clay, then sand, diluted with water and strained through a sieve. You can add to the strength of 75-100 kg of cement per 1 m3 of solution.

Cement-mortar prepared from different ratios of cement, lime and sand in the following sequence. Of cement and sand are preparing a dry mixture, and lime putty is diluted with water until thick milk and strained through a sieve. Lime milk is poured into dry mixture and mix thoroughly. Instead of lime paste, you can use clay in the same proportions. Composition and ratio of these solutions and their names are listed in Table 10.

These solutions are used for both above-ground masonry walls and foundations in dry soils. In malovlazhnyh soils should be at 1 m3 of sand in the cement-mortar to take not less than 75 kg of cement, cement-clay - 100 kg, in very wet and saturated soil water - 100 and 125 kg.

Cement mortars are most common in construction.

They lay foundations and other structures that are below the groundwater level. Apply them also to masonry walls, but they are very cold, although have increased strength. Ratio of cement and sand in a solution 1:2,5-6, ie, 1 part of cement take from 2.5 to 6 parts sand. Depending on the ratio of parts of sand and cement obtained by different brands of the solution.

Prepare the solution as follows. Sand measure, poured a hill, on top - the right amount of cement and mix thoroughly until a homogeneous dry mixture, which shuts water, mix thoroughly and use within one hour. Later use reduces its strength. Sand to prepare the solution using a clean, where necessary, washed. For the preparation of a m3 of solution depending on the ratio required different amounts of pure water. Thus, at a ratio of 1:3 to 190 liters, and at 1:6 - 153 liters of water.
