Keramzitoblok and foam block - modern building materials, which possess a number of advantages over the brick.
The first is made of expanded clay and cement, the second - from cellular concrete, due to different composition, they have different characteristics.
Choosing one or the other material should be in accordance with its objectives and requirements.
Pros and cons keramzitobloka
Keramzitobloki - a large, light and durableblocks made of foamed clay known as expanded clay, cement and water. Ease of foam material is achieved due to the structure of expanded clay, and the sheath covering the pellets has a high strength. keramzitobloka density can be varied depending on the method of production - from 400 to 1800 kilograms per cubic meter.
An important advantage compared keramzitoblokawith many modern building materials - environmental and health safety. The second main advantage - high insulation walls of these blocks is optionally further strengthen the home of them can be built in a cold climate.
Keramzitobloki can be used in low-rise and high-rise in construction: each unit has special cavities, which can be made rigid frame.
The size of the expanded clay block about fourtimes larger than a brick. Laying conducted in the same way as brick, but at the expense of ease and dimensions it is performed easily and quickly. Keramzitoblok blends well with a variety of building materials. It is easy to handle, and the chemical and physical impact on it is minimal.
Disadvantages keramzitobloka - relative fragility and porosity in comparison with concrete.
Pros and cons of the foam block
Foam block is made of foam concrete,having a honeycomb structure, through which the properties are close to those of keramzitoblokov. He also has excellent thermal insulation properties - to be more precise, even higher than that of the expanded clay, so if your primary goal - good insulation of the house, it is best to choose a foam block.
Air blocks, too light, making them easy totransportation and laying. The structure of the material makes it easy to compare it, saw, hammer nails in his face. But the mechanical strength is not the best material.
Air blocks almost not afraid of dampness, unlikekeramzitoblokov that have low water vapor permeability. Cellular concrete blocks are well passed steam, allowing the homes to "breathe", creating a healthy environment and letting out harmful substances. In the summer in a cool building, and in the winter due to good thermal conductivity - heat.
Foam blocks are rarely used in high-riseconstruction, but among the low-rise buildings occupy one of the first places among all materials. They are very durable and easily withstand freezing and thawing cycles, as opposed to the expanded clay.
