Science knows no bounds, and as it progresses unprecedented, more advances will be made, especially in the department of civil engineering and manufacturing. Cement and concrete were one of a marvel provided to us by chemical engineering upon which our urban civilization thrives as we know today. Construction chemicals in Pakistan on the other hand deals in all the necessary areas where there is a need or which helps us build construction on a rapid scale. Although, the chemical availability in Pakistan is of the question. Good thing that we as one of the emerging companies in construction chemicals in Pakistan want to let our readers know about major types of chemicals used and their classification.
Main categories of construction chemicals
No one can add all of the chemicals that are available in Pakistan in a single post, for that we might need an excel sheet and a lot of time on our hands. What we are intended to provide in today’s blog is the types of construction chemicals in Pakistan which could be taken as major categories upon which we can characterize all the chemicals used in construction. In practice, there are 4 types of construction chemicals used during civil jobs. Let discuss it in detail and understand what does the chemical does actually.
The most used construction chemicals in Pakistan which supersede all the rest is concrete admixture. Although it’s in itself a broad type which can be further sub-divided into other categories, In short, concrete admixtures are chemicals that are added in concrete other than portland cement, water and aggregated elements to harden the concrete, or for other purposes required by the experts. Talking about additional functions of concrete admixtures, it can be distinguished into five areas which include: air-entraining, water-reducing, retarding, accelerating and plasticizers.
Asphalt has a huge requirement in urban construction that ranges from road cementing to waterproofing. Although asphalt can be found in raw nature, make the most of it, and depending on our requirement, certain construction chemicals are required to add over raw asphalt. These chemicals are usually treated as polymers or modifiers, whose main objective is to boost the overall performance of the asphalt. It can be as oxidants, antioxidants, extenders, or hydrocarbons. A civil expert will choose the require chemical as modifiers depending on the nature of construction.
Adhesive and sealant
In construction, we require glues, bonds and sealing agents to deal with cracks, joints, and openings. For all these practical uses, adhesive and sealant come into our aid. It’s fair to say that adhesive and sealants are considered one of the most used construction chemicals in Pakistan, and it’s used by both professionals and amateurs alike. It comes in low-cost as well as high-cost material, depending on our requirements. Usually, chemical suppliers in Pakistan have construction based sealant which is classified into higher quantity, while for personal or residential use, lower quantity based adhesive and sealants are used.
In definition, a protective coating is a layer overlapped over another material to protect it from corrosion and other preventive measures. As a construction chemical in Pakistan, the most commonly used protective coatings are non-metallic coatings, such as polymers, epoxies, and polyurethanes. Waterproofing services can also be classified into protective coating since its main job is to protect your surface from water, the chemical helps it to make it water-resistant. If we are dealing with metal sheets, special types of polymers are used to make it corrosion-proof.
Construction chemicals for waterproofing
Waterproofing is categories as a protective coating and comes under the umbrella of construction chemicals in Pakistan. The practical usage of waterproofing chemicals is quite used among residential and commercial sectors. The application and chemical both are handled by specialist companies in Pakistan which are responsible to not only provide the waterproofing service but also to ensure that proper application is provided. If there is some leakage still present, these waterproofing companies provide several years of warranty for their product and service so that customers can simply avail their warranty to have repaired or rechecked free of cost.
It’s fair to say that we have only touched the tip of an iceberg by informing a little bit about types of construction chemicals in Pakistan. But in reality, the chemicals are further sub-divided into many variants which are both unique and important in civil engineering.
