Advantages and disadvantages of aerated concrete and porous brick

When choosing a wall material every buyer asks the question: what is better? No company that sells aerated concrete, will not tell you about the shortcomings of their product. The same you will not hear from the manufacturer and supplier of ceramic porous bricks. Consider in this article all the disadvantages and advantages of each individually material. Aerated concrete blocks due to a number of advantages have earned justified popularity in construction. This material has long been used for the construction of various types of partitions and fences, exterior and load-bearing walls. Газобетон и поризованный кирпич

Advantages of aerated concrete:

  • Builders have long noticed that the cost of erecting wall structures made of aerated concrete is significantly lower than the price of other materials such as bricks or stone;
  • The use of aerated concrete will allow you to save significantly on additional insulation materials. This material has a low thermal conductivity, which provides a comfortable microclimate in the room in summer and winter;
  • Non-combustible material that completely prevents the spread of fire;
  • Aerated concrete blocks are very popular in metropolitan areas due to its excellent soundproofing qualities;
  • This material is absolutely environmentally friendly;
  • Aerated concrete is vapor permeable. This property allows moisture accumulated inside the block goes outside, so the blocks of this material is not subject to rot;
  • Aerated concrete blocks are frost-resistant and moisture-resistant, they can be used for construction in a variety of climatic zones;
  • Scientific research in laboratories has shown that even in conditions of high humidity and high temperatures, aerated concrete blocks are absolutely resistant to bacteria, fungus and mold;
  • Durability of this material is time tested. Many buildings built with aerated concrete 70-80 years ago, are still in excellent condition;
  • Easily transportable due to its low weight;
  • Processed by any tool (manual or electric), can be transformed into various architectural forms.

Disadvantages of aerated concrete:

  • Aerated concrete products are not strong enough, which can lead to cracks over time inside the block itself due to improper laying;
  • It is better not to use dowels or other fasteners to work with blocks of this material. Only self-tapping screws can not cause damage to aerated concrete, but they are subject to oxidation;
  • Without a preliminary primer does not hold plaster. This is due to the high water absorption of the material.
The porous brick is used in the construction of residential buildings up to 9 floors, various administrative buildings up to 23 floors. It can be used to wall industrial and domestic furnaces, used for masonry foundations.

The advantages of ceramic bricks:

    • Excellent heat insulation. Due to the presence of hollow holes, the heat is retained in the block. This allows you to significantly save on home heating costs and do not spend money on additional insulation;
    • The low specific weight of such bricks makes it cheaper to transport the material to the construction site and facilitates the work of the builders themselves. In addition, the smaller the weight of the walls, the less you spend on laying the foundation;
    • Larger shapes, in which ceramic bricks are available to significantly speed up the construction process;
    • Has high noise insulation properties, provides good vapor barrier;

  • Since these blocks have a large size and have no joints, work with them in the construction is greatly simplified, and the amount of mortar required for laying decreases;
  • It does not require priming before applying plaster, and is well compatible with any finishing materials;
  • Environmentally friendly material, consisting mainly of sand, clay and other natural materials;
  • Does not warp over time, does not rot or mildew.

Disadvantages of ceramic blocks:

  • Often the blocks have a mismatch in height and width, which complicates the masonry process;
  • It will take enough experience and strength to drill a hole in the wall of this material. In order to strengthen the expensive TV on the wall, it is necessary to use a sufficient number of anchors and dowels;
  • The fragility of the ceramic block with proper masonry can not be noticed. However, if you drop one brick, it will fly apart.

The differences between the two materials are obvious:

  • Thermal insulation. Aerated concrete blocks will better protect your home from the penetration of cold air in the case of masonry 400 mm, while brick masonry should be about 500 mm. Consequently, the material consumption in the second case increases. However, the insulating properties are reduced if the rules of thin-walled masonry aerated concrete with special glue are not followed. If the aerated concrete planted on cement mortar and increase the size of the joint (which is done in order to save money most construction companies);
  • Brick is more frost-resistant and durable;
  • Structures made of aerated concrete over time, subject to shrinkage, which manifests itself in the appearance of cracks. Especially this quality can manifest itself in the area of chimneys. Brick is completely not subject to moisture shrinkage;
  • Fire resistance, environmental friendliness compared blocks are the same. The speed of construction work is also identical;
  • It should be noted that in the processing of aerated concrete, of course, wins. However, as noted above, this material requires special treatment when installing structures and equipment on it, as more fragile when exposed to mechanical action. Brick, in turn, is more reliable and strong, but difficult to drill, sawing;
  • The price of aerated concrete is lower. In addition, a small amount of bonding material is used for its masonry. Brick is more expensive, and the purchase of mortar you will have to splurge.
Unambiguous decision in the debate over what material is better, you are, perhaps, will not give any highly qualified specialist. The choice of wall material depends, above all, on your financial capabilities and individual wishes of the buyer to the properties.
