Reinforced concrete has a long history dating back to the 19th century and according to the historical record, it was Francois Coignet, an industrialist from France who first developed prefabricated, structural and reinforced concrete. Since then the technology of preparation and use of reinforced concrete has undergone tremendous changes. When cement, crushed stone and sand are mixed in an appropriate quantity with water, then it becomes a rigid mass. But, this mass is prone to breakage when high tension is applied or due to bending. This situation can be averted when high tension steel reinforcing mesh is placed in the concrete. The steel will reinforce the strength of the concrete and resist bending and compression.
Types of steel mesh:
The reinforcing mesh is prefabricated steel which is welded at appropriate points. The mesh is available in three designs namely, trench design and square grid and rectangular pattern with appropriate spacing between the mesh. The type or grade of the steel rod used in the making of reinforcing steel mesh and the spacing between the mesh depends on the application of the mesh in the construction work.
Choice of steel for reinforcement:
The steel used for reinforcing mesh is called by different names like the rebar, reinforcement steel and reinforcing bar. The choice of rebar for purposes of reinforcement is because of the homogeneity in the thermal expansion properties of both concrete and steel. In addition to this, both rebar and concrete have bending ability. Among all other types of bars, steel bars effectively bond with concrete and thereby it becomes a perfect passive reinforcement structure. However, now glass fibers, steel fibers, natural and also synthetic fibers are also used to reinforce concrete. This type of concrete is called as ‘Fiber Reinforced Concrete’. However, this type of concrete has a certain specific application in the construction process.
Need for floor sealer:
One of the notable qualities of concrete is its bonding strength in the compression state. But, concrete by itself does not have strength in tension. This shortcoming is offset by using a steel rebar of appropriate quality. Therefore, reinforced concrete derives its strength from both steel rebar and the concrete.
Concrete when appropriately reinforced becomes a strong mass capable of withstanding pressure and bend. Yet, after the fabrication, the surface area of reinforced concrete should be properly sealed so as to prevent staining, corrosion and even the surface damage caused in the fabrication process. This is done by what is known as concrete floor sealer.
The floor sealers are available in different types like the topical sealer, acrylic resin, penetrating sealer, epoxy sealer and so on. Normally, the sealer dries within about 2 to 3 hours. However, once the concrete sealing is applied it should be cured for a certain specific duration which is unique to the sealer you use. For effective sealing, the sealer should be applied strictly according to the guidelines prescribed by the manufacturer. Keeping in view the norms of the government, now the sealers are made environmentally friendly.
Buy from the reputed manufacturers:
It can be said that the utility of reinforced concrete is best served only when you use steel of good quality and also effectively seal the concrete after reinforcement. You should buy the rebar from reputed manufacturers like the https://www.bestbar.com.au so that you get rebar of superior quality which actually enhances the strength of the reinforced concrete.
