Porous ceramic blocks are madefrom a mixture of clay, water, and sawdust, which upon subsequent firing at high temperatures burn out to form a porous structure. This building material is characterized by high thermal insulation and sound absorption properties.
Porous blocks are used for the construction of high-rise buildings, and in the individual building.
Features masonry porous ceramic blocks
This eco-friendly large format walla material having a vertical connection "tongue and groove", can significantly increase the speed of construction, reduce its time and reduce cost. Its use is advisable in the construction of buildings and constructions of any complexity, and allows you to realize the most daring architectural solutions.
For the construction of the masonry must be keramoblokovbuy insulating masonry mortars, prices for which are somewhat higher than the traditional cement-sand or cement-lime, which is not recommended in this case. This difference is due to too high thermal properties, due to which the sutures made from conventional solutions, the conductors become cold outside and negate the entire heat-insulating effect of the porous ceramic blocks. The solution should be prepared for keramoblokov, strictly observing the instructions. 20 kg of dry blend obtained special about 30 liters of solution, its consistency should not be too thin, so it does not block vertical impingement holes in.
Sutures are used for laying porous ceramic blocks
Just as for masonry, in this caseused bed seam. Carrying it is necessary to strike a balance - it should not be too thick in order not to decreased strength of the masonry, and at the same time, too thin to be able to even out tolerances in block sizes. Usually fairly seam thickness of 12 mm, and wherein the solution should be applied uniformly. For load-bearing walls and walls experiencing load statistics, pastel seam better perform continuous, but for the partitions that are not under stress, it can be done intermittently.
Depending on the geographical area for the construction of exterior walls can use blocks of different thickness, which gives substantial savings for the southerners.</ Blockquote>
The vertical construction joint is used formasonry bearing walls, both external and internal, but in this case the turnaround time and the flow of solution is greatly increased. When using dressings use ceramic blocks "tongue and groove" practically excludes its use, which reduces the construction period. Laying of the blocks does not require a solution to perform vertical joints and the outer wall, avoiding heat, is being built in a row. Insulation is provided by the fact that in the horizontal direction of blocks stacked end to end to each other, ensuring the integrity of a monolithic building structure. In addition, the lack of solution allows the walls to dry much faster and almost immediately acquire high strength and heat resistant properties.
Technological subtleties masonry porous ceramic blocks
An important step is the laying of the first row,which is necessary to provide reliable waterproofing between the wall and the wall is being built basement. Before starting work on the basement wall is necessary to put a waterproof solution, on top of which lay a waterproofing material, its width should be 2-3 cm longer than the width of the wall being built. On the waterproofing material is applied to a thick solid pastel seam, which, starting from the highest place, it is necessary to align with the level. To blocks under its own weight is not immersed in the solution, placed on top of a thin layer of joint cement.
Works on masonry walls keramoblokov should be carried out in dry weather at temperatures above 5 ° C. In case of rain the finished masonry should be closed.</ Blockquote>
First you need to put the blocks on the corners andconnect them with a special device - a cord-prichalku on the outer wall. The remaining blocks are laid on it, they are simply inserted one into another, preventing horizontal displacement. To size sawing blocks using a desktop or a circular hand chain saws. After the first row is laid, it needs time to dry - for at least 12 hours.
The technology of masonry walls is quite simple, but hereIt has its own quirks. Before you start laying the next series, the surface of the lower row of blocks must be wetted with water. Solution pastel horizontal seam in the construction of exterior walls is applied to the entire surface of the blocks, while it should be collected from the outer surface of the wall with blades. It is necessary to monitor that the vertical joints between adjacent rows of the same size and used to control the level of the horizontal and vertical position of the stacking blocks. In case of deviations, the blocks can knock a rubber mallet.
Particular attention is paid to ligation and masonry walls. That it ensures the integrity of the structure being built. The shift between the individual blocks in adjacent rows must be at least 0.4 times the height. Ligation of the external walls with internal made using steel anchors with perforation, they are placed in pastel stitches of each odd row. Because of the porous masonry blocks is facing, requires bandaging of a laying and facing. As a rule, front brick of Russian production and ceramic blocks have a single frequency factor, which greatly simplifies the dressing.
