Construction chemicals are specially designed chemical products used in the construction of buildings. Choosing the right construction chemicals is essential to accelerate new or existing construction projects. These chemicals help to strengthen the structure and prolong the life of buildings.

The construction chemicals are added to various building materials to enhance the latter’s productivity and usefulness. Besides this, adding construction chemicals to building materials also ensures overall safety of the structure.

It is crucial to choose construction chemicals carefully to ensure they follow the industry requirements. This helps to assure the dependability, effectiveness, and safety of the construction products. The most critical point to remember when choosing construction chemicals is to make sure that they are certified from the Bureau of Indian Standards (BIS) and the Indian Green Building Council (IBGC).

In this article, we will find out the factors to consider when choosing construction chemicals, the types of construction chemicals used, and how to choose construction chemicals correctly.

Factors To Consider When Choosing Right Construction Chemicals

Not all construction chemicals are equal hence you need to choose the ones that completely fulfill your project’s specific requirements and standards. Every construction chemical is developed to solve specific problems or enhance properties of construction materials.

Before you choose construction chemicals you should carefully check certain factors to ensure they fulfill your construction requirements. This includes analyzing the type of construction material, desired characteristics, and environmental conditions. Ask yourself whether you want to waterproof a building, increase concrete strength, or repair damaged structure.

By determining the specific requirements, goals and challenges of the construction project, it becomes easier to correctly choose construction chemicals.

Below are listed the factors you should analyze before choosing construction chemicals –

Performance Requirements

The exact performance requirement of the construction project is a major factor in selecting the right construction chemical. Some of the most common performance requirements include –

Enhancing strength – If the construction project needs enhanced structural strength, then you should choose construction chemicals that improve the tensile, flexural, and compressive strength of the mortar or concrete.
Durability – Some building projects are in places that experience harsh weather conditions, or in heavy traffic areas. Such structures require construction chemicals that will improve overall durability. This choice of construction chemical can effectively decrease the risk of degradation and prolong the building’s life.
Bonding/Adhesive Strength –If you require joining two different construction materials, such as masonry to wood or concrete to steel, then choosing adhesives and sealants with good adhesive properties is necessary.
Waterproofing –Any building project that is likely to be exposed to moisture or rain needs waterproofing construction chemicals. These chemicals are designed to protect structures from deterioration and damage by preventing water filtration.
Chemical resistance – Chemical resistance to certain chemical compounds or corrosive substances is an important factor to consider when choosing construction chemicals. This is especially needed if the building project is in an industrial or chemical environment.
Fire resistance – If you are concerned about fire safety in a building, then it is important to choose a construction chemical that is fire-resistant.

Compatibility with Existing Materials

Before choosing construction chemicals, check to see how they will integrate with the construction materials being used. Compatibility with existing construction materials is crucial to ensure that the different chemicals do not react and cause a negative effect on the structure. For example, when using admixtures with concrete, make sure that they do not compromise the curing process, or cause undesired side effects.

Long-Term Durability

Durability of building structures is another critical factor to consider when choosing construction chemicals. Products that help to extend the life of buildings are essential to maintain the aesthetic and durability of the structure. Hence, you should think of choosing construction chemicals that provide longevity to buildings. The chemicals should offer good resistance to environmental factors, such as moisture, extreme temperatures, UV radiation, etc.

Cost Considerations

Construction budget is another major factor in determining the choice of construction chemicals, since it controls the purchase of building materials. It is important to choose good quality construction chemicals that fulfill your building requirements. However, it is also important to keep the budget in mind.

Besides the upfront costs of construction, you should also consider the long-term savings the chemicals can provide, as in reducing maintenance expenses by increasing durability.

Environmental Impact

Today, increasing numbers of industries are becoming environmentally conscious. Hence, it is essential to analyze the environmental impact of construction chemicals before buying.

Construction experts recommend using construction chemicals that comply with environmental regulations and are eco-friendly. Sustainable chemical products help decrease the carbon footprint of your construction project and lower its impact on the natural surroundings.
