The ABCs of Concrete Resistance

maxresdefault

Resistance of concrete is the ability of a material to maintain its properties for a long time: fire and heat resistance, cold resistance, resistance of concrete to chemically aggressive environment, water and gas, maintaining its performance when working in adverse environmental conditions without significant damage and destruction. The article is prepared in collaboration with Telling Company experts, a successful UK-based engineering enterprise, massively utilising hydraulic lime, lime mortar and concrete solutions in its projects.

Resistance factors in a nutshell

A particularly high expansion of concrete hardening occurs during the formation of calcium sulfoaluminate. Concrete corrosion can occur if there is moisture in the air, and various acid gases. For example, sulfur dioxide discharged from furnace boilers, locomotives or sets of certain chemicals combines with moisture in the air and water vapor to form sulfuric acid, which destroys the concrete as well as the free acid in aqueous medium. Processes of chemical corrosion of concrete can not be considered independently of the physical and physico-chemical processes occurring in the concrete under the influence of an aqueous or gaseous medium. A crucial impact, in particular, has a three-dimensional deformation, resulting moisture exchange (absorption of water and its evaporation), the process of freezing and thawing, seepage and water filtration, diffusion processes, moving moisture in concrete, and so on.

The Miraculous Glass Reinforced Concrete

Glass reinforced concrete is fairly considered to be one of the most versatile building materials that stand in the service of modern architects and designers. The material production technology was developed over thirty years ago and since then glass reinforced concrete  has managed to establish itself as an indispensable tool and made ​​a significant contribution to the economy, technology and aesthetics of the building industry.

The material is comprised of several groups of elements: glass reinforced fiber is a collective term which includes a family of materials designed for a wide variety of purposes. Since its introduction in 1969, GRC has been implanted in global building practices around the globe, and now it is utilised by construction experts in 120+ countries.

In the years since the advent of GRC on the global construction market, the material has fully formed as a finest quality building component, plus the scope of its use has been significantly expanded.

Glass reinforced concrete has already firmly established in Europe (England, France, Germany), the United States, the countries of the Arab East, Japan and South East Asia (just remember the amazing Petronas Towers in Kuala-Lumpur), Australia and New Zealand.

The creation of the next-gen material was largely driven by the desire to improve the traditional concrete by improving its properties and thereby expanding its capabilities.

Admittedly, a major concrete disadvantage lies in its stone nature and low tensile strength. In reinforced concrete the weak point is partially eliminated by enabling metal fittings to deal with pressure. Dispersed reinforcement of concrete with fiberglass has a high tensile strength and significantly increases the strength of concrete stretching and bending.
