Refractory concrete - a way to keep the heat under control

few introductory words about the refractory concrete

Typically, this option is the concrete used in the construction of furnaces and chimneys, both in residential and industrial construction.Manufactured in accordance with all the rules, the material provides protection and security.Depending on the purpose of purchasing specialists various options for concrete - cellular, dense or light.

Such concrete can also be used as heat-insulating material.Due to the need to work with the material in the same way as with conventional concrete, reduces the cost of construction work.This material provides excellent resistance to temperature extremes, does not change its properties after heating, which is why heat-resistant concrete is becoming the best option in the construction of specialized facilities.

Development for critical temperature conditions

In practice, conventional concrete mixes do not tolerate high temperatures.Even those options, which are considered some of the most high-quality and expensive, can not guarantee the safety at a temperature above 150 degrees.Material begins to crumble to lose shape, whereby the entire structure suffers.

That is why experts have developed special formulations preserving properties at high temperatures.Today, there are so-called vysokoogneupornye concretes, which are assessed in conditions where the temperature exceeds 1770 degrees refractory options that work with temperatures of 1580 to 1770 degrees, and heat-resistant , their limit of 1580 degrees.

Any heat-resistant concrete consists of a base and a filler in the manufacture of the material used specific elements: water glass, aluminum cement, expanded clay and more.Refractory

embodiment, which includes alumina, does not respond to acid, which gives it additional benefits.

evaluating the effectiveness of the material, we can confidently say that the use of heat-resistant concrete is much more economical than buying a heat-resistant tiles.The fact that the laying of the tiles, the specialist has to use a special solution, collapsing under the influence of temperature.With respect to concrete such surprises can occur.

Features selection of heat-resistant concrete

To make concrete fire-resistant and suitable for use in areas with elevated temperatures, for example, for the construction of the furnace, in the added asbestos, alumina cement, water glass and barium cement.All these additions become one with the total curable component, and also the refractory.

The structure consists of conventional concrete elements which, when heated, undergo a process of dehydration or dehydration.Subjected to such a test concrete structure quickly cracked, broken, to stop the process is almost impossible.To these troubles did not occur in places with high temperature refractory formulations should be used.

Considering refractory concrete, we can note the high content of impurities in its composition.Each element fulfills its role, linking the material at higher temperatures, making it more durable.Depending on the requirements selected material with the addition of a specific element, so that some fillers can withstand temperatures only up to 1,580 degrees, and other fine and show themselves when exposed to 1770 degree temperature.
