When one talks about concrete, the word impenetrable barrier comes to our mind. Concrete is one of the impervious, composite man-made material consisting Cement, Aggregates & Water. Modern day concrete comes with addition of Admixtures to impose additional strength, imperviousness & work-ability to the concrete.
With similar understanding, most developers/realtors & people choose concrete or concrete products while making structure especially foundations, columns, beams, slabs, terraces & roofs.
Concrete consists of Cement; Cement consists essentially of compounds of lime (calcium oxide, CaO) obtained from calcareous (lime containing raw materials) mixed with silica (silicon dioxide, SiO2) and alumina (aluminum oxide, Al2O3), these oxides are obtained from clay. This all raw material when processed for Crushing – Grinding, Blending, Burning and Fine Grinding forms cement. This process makes the cement rich in calcium carbonate content which has water impervious property. Due to competitive market and imposed regulation by government considering environmental hazards in formation of Calcium carbonate (CaCO3) for cement; Effective content of Calcium carbonate (CaCO3) in concrete is getting restricted.
Also, purity & grade of modern day raw material are compromised due to restricted availability of natural resources. Resulting in formation of concrete with poor resources.It’s matter of fact that concrete is now modified to be used with fly ash, which is relatively considered to be safe in environmental hazard then manufacturing of cement. Concrete made using fly ash are tending to become more & more in day to day use.The imperviousness of the concrete in case of concrete made with fly-ash rests on quality of fly ash used. The poor the quality of fly ash; porosity of concrete increases along with loss of strength.
Yes, you got it right; Even Moisture is an enemy of concrete. This is very much true because it starts to weakens up the concrete and deteriorates it from within. Due to the moisture; fungus, staining and efflorescence are obvious visible reasons towards Concrete problems.
To keep your structure safer in longer run, you need to protect the concrete; To protect the concrete from water damages you need to have Terrace Waterproofing & Basement Waterproofing.These types of services could be carried / rendered / executed by Waterproofing expert.
Concrete seeps water in form of small capillary formed during casting and curing process of concrete. These capillary sucks the moisture / water due to difference of pressure within and outside the concrete, which result in presence of moisture or water content within concrete.Making waterproofed concrete from within is a unique way of sealing the concrete from any form of water. If it’s core is waterproofed, it doesn’t allow passage of water through it. Concrete waterproofing could be done for New as well as old concrete. Ideal choice would be to seal the concrete with good concrete sealer after complete curing of casted concrete.
