Construction chemicals are an essential component of modern-day construction projects in Bangladesh. These chemicals are specialized substances that are added to construction materials such as concrete, cement, and mortar to enhance their properties and improve their performance.
In Bangladesh, the construction industry has witnessed significant growth in recent years. As the country continues to develop and modernize, the demand for high-quality construction materials and chemicals has increased. Today, construction chemicals play a vital role in the success of many construction projects in Bangladesh.
The use of construction chemicals in Bangladesh is widespread and includes a wide range of products. Some of the most commonly used construction chemicals in Bangladesh include:
Waterproofing Chemicals: Bangladesh is known for its heavy rainfall, which makes waterproofing chemicals essential for construction projects. These chemicals prevent water from penetrating the building's structure and causing damage to the structure. Normally, bituminous, acrylic and epoxy based waterproofing materials are used in several application method like membranes, coatings, spray, paints etc.
Concrete Admixtures: Concrete admixtures are used to improve the properties of concrete, such as strength, damp proofing, durability, and workability. In Bangladesh, concrete admixtures are widely used in construction projects, especially in domestic & commercial high-rise buildings. Among these, the integral waterproofing admixtures are being widely used in Bangladesh.
Protective Coatings/ membranes: Protective coatings are applied to the surface of the building to protect it from environmental factors such as sunlight, water, and air pollution. These coatings increase the lifespan of the building and reduce maintenance costs.
Sealants: Sealants are used to seal gaps and joints in the building structure to prevent the entry of water and air. In Bangladesh, sealants are widely used in commercial buildings, bridges, and tunnels.
Rooftop Heat proofing: Rooftop heat proofing is an important consideration for buildings in areas with high temperatures and strong sunlight. Without proper heat proofing, the rooftop can absorb a significant amount of heat, which can transfer into the building and cause discomfort for occupants. By applying heat proofing materials such as reflective coatings or insulation, applying admixtures, and Cementous solutions rooftops are heat and waterproofed in Bangladesh.
Polymer-modified Mortars: These are specialized mortars that are used for tile fixing, plastering, and concrete repairs. The latest polymer-modified mortars are highly flexible, provide excellent adhesion to the substrate, and have a long working time.
Epoxy Flooring Systems: These are specialized flooring systems that are used in high traffic areas such as hospitals, airports, and factories. The latest epoxy flooring systems are highly durable, provide excellent resistance to chemicals, and have a non-slip surface.
Repair and Rehabilitation Chemicals: Repair and rehabilitation chemicals are used to repair damaged concrete structures. These chemicals increase the strength and durability of the structure, preventing further damage and increasing its lifespan. There can be two types of repairing chemicals-
Cementitious repairing chemicals are composed of Portland cement, aggregates, and additives. The aggregates used can be either fine or coarse, depending on the type of repair required. The additives can include water-reducing agents, plasticizers, accelerators, and retarders. Some examples of cementitious repairing chemicals are:
Mortars: These are used for repairing concrete surfaces such as walls, floors, and ceilings. Mortars are typically composed of cement, sand, and water.
Grouts: These are used for filling voids and gaps between concrete surfaces such as columns, beams, and walls. Grouts are typically composed of cement, sand, and water, along with additives such as plasticizers.
2. Non-cementitious Repairing Chemicals:
Non-cementitious repairing chemicals are composed of polymers, resins, and other synthetic materials. They are used for repairing surfaces that require high strength and durability, such as industrial floors, bridges, and highways. Some examples of non-cementitious repairing chemicals are:
Epoxies: These are two-part systems that consist of a resin and a hardener. Epoxies are used for repairing cracks, filling voids, and restoring structural integrity to damaged surfaces.
Polyurethanes: These are flexible and durable materials that are used for sealing and repairing cracks in concrete surfaces. Polyurethanes are also used for coating and protecting concrete surfaces from water and chemical damage.
Acrylics: These are water-based materials that are used for repairing and resurfacing concrete surfaces. Acrylics are easy to apply and can be used for both indoor and outdoor applications.
Importance of Construction Chemicals in Bangladesh
Construction chemicals play a vital role in the success of many construction projects in Bangladesh. Here are some of the reasons why construction chemicals are essential in Bangladesh:
Weather Conditions: Bangladesh experiences heavy rainfall, high humidity, and extreme temperatures, making it essential to use construction chemicals that can withstand these conditions.
Quality of Construction: The use of high-quality construction chemicals improves the quality of the construction and increases its lifespan.
Safety: Construction chemicals play a crucial role in ensuring the safety of the building and its occupants. These chemicals prevent the building from collapsing, prevent water damage, and reduce the risk of fire.
Cost-Effective: The use of construction chemicals reduces the cost of construction by increasing the lifespan of the building, reducing maintenance costs, and preventing the need for expensive repairs.
The use of construction chemicals in Bangladesh has been widely accepted and appreciated by the masons and engineers working in the construction industry. They believe that the use of construction chemicals has significantly improved the quality and durability of the buildings in the country.
Bangladeshi masons and engineers consider the use of construction chemicals as a necessity rather than a luxury. They believe that the harsh weather conditions and poor quality of construction materials make it essential to use construction chemicals to improve the properties of the building.
Among all the construction chemical products, Mix & Fix Cement Booster has gained popularity among the masons and engineers in Bangladesh. It is a specialized admixture that is added to cement to improve its properties. Mix & Fix Cement Booster enhances the strength, workability, and setting time of cement, making it ideal for use in high-strength concrete applications.
Mix & Fix Cement Booster is a high-performance product that provides several benefits, including:
Increased Compressive Strength: Mix & Fix Cement Booster significantly improves the compressive strength of concrete, making it suitable for use in high-rise buildings and other critical applications.
Improved Workability: Mix & Fix Cement Booster improves the workability of concrete, making it easier to handle and place.
Faster Setting Time: Mix & Fix Cement Booster reduces the setting time of cement, allowing faster construction and reducing construction time.
Cost-Effective: Mix & Fix Cement Booster is cost-effective and provides excellent value for money. It reduces the amount of cement required, reduces construction time, and lowers the overall cost of construction.
In conclusion, the use of construction chemicals in Bangladesh has significantly improved the quality and durability of buildings in the country. The masons and engineers in Bangladesh believe that the use of high-quality construction chemicals is essential for building structures that can withstand the harsh weather conditions and other challenges. The latest construction chemical products being used in Bangladesh offer excellent performance and provide several benefits, including improved strength, workability, and durability. Mix & Fix Cement Booster is one such product that is gaining popularity among the masons and engineers in Bangladesh due to its excellent performance and cost-effectiveness.
