The hot temperature in Bangladesh causes issues when it comes to concrete construction. Concrete dries fast in hot weather. It results in cracks and weak foundations. 

For maximum strength and longevity, it’s essential to choose the proper concrete mix. Specific kinds of concrete with additives assist in retaining moisture and reduce the impacts of heat. These mixes guarantee long-lasting results in construction tasks by enhancing workability and setting time. 

Mir Ready-Mix Concrete is here to inform you about the best concrete for hot weather conditions in Bangladesh! 

Best Concrete for Hot Weather Conditions in Bangladesh: A Comprehensive Guide

Discover the best concrete mix for hot weather construction in Bangladesh. Our guide covers ideal cement types, water-cement ratios, and expert tips for successful projects. Let’s find out which concrete will be best for you to use in Bangladesh during hot weather.

PPC or Portland Pozzolana Cement 

The combination of Portland cement and pozzolanic minerals, including fly ash, is used to produce Portland Pozzolana Cement (PPC). It prevents cracking since it creates less heat throughout the curing process. PPC requires time to set. It allows you more time to set up and finish. 

Furthermore, it improves workability, which facilitates blending and application. Such type of cement is strong and resistive to chemical decay. PPC is commonly used in both residential and commercial structures in Bangladesh. It provides stability and durability in warm weather conditions.

PSC or Portland Slag Cement 

Granulated blast-furnace slag and Portland cement are mixed to produce Portland Slag Cement (PSC) It is suitable for high temperatures because this mixture releases less heat when hydrated. 

It’s also highly durable and immune to moisture and chemical damage. Concrete that contains PSC is tougher and less porous.  

Due to its low water absorption, it can resist the occurrence of cracking. PSC has remained highly reliable and stable over the years, providing reliable performances, especially in construction projects involving high structures like bridges and houses, which have to face severe weather in Bangladesh. 

HPC or High-Performance Concrete  

The goal of high-performance concrete (HPC) is to reach certain standards of robustness and durability. Due to its low water-to-cement ratio, it is firmer. 

As HPC is resistive to variations in temperature and cracking, it performs effectively in hot weather. Furthermore, this concrete has superplasticizers that increase workability and facilitate placement.  

Bridges and skyscrapers are examples of high-stress applications where it works well. When strength and durability are essential, HPC is utilized in Bangladesh to ensure that structures can endure harsh conditions throughout time.

Lightweight Concrete 

Lightweight aggregates, such as pumice or expanded clay, are used to make lightweight concrete. Because this kind of concrete is far lighter than ordinary concrete, structures weigh less overall. Lightweight concrete lowers the chance of cracking and helps regulate temperature swings in hot weather. 

Additionally, it improves thermal insulation, which raises the energy efficiency of structures. Lightweight concrete is widely used in Bangladesh for precast elements and high-rise buildings because it improves stability and speed of construction while efficiently controlling heat. 

SCC or Self-Consolidating Concrete  

SCC can fill molds without vibrating and is very flowable. This facilitates use in hot temperatures, where conventional techniques could cause issues. SCC ensures a consistent mix by preventing bleeding and segregation. It works best for substantial reinforcement and intricate shapes. 

It is utilized in high-strength applications, precast constructions, and architectural features in Bangladesh. Its simplicity in placement and finishing ensures robust, long-lasting results under difficult circumstances while saving time and labor expenses.

Fiber Reinforced Concrete  

The main components in fiber-reinforced concrete are very fine fibers such as glass or steel fibers. These fibers help to keep the fabric intact from shrinkage and cracking, especially during hot climates. This results in increased strength and more malleability of the concrete, particularly when a lot of fibers are added.  

It is most suitable for pavement and heavy-duty flooring, especially when considering durability and resistance to chemical attacks. Due to its low thermal conductivity and durability in construction, this fiber-reinforced concrete is expected to increase in Bangladesh. 

Admixture-Modified Concrete  

To improve performance, Admixture-Modified Concrete incorporates unique chemical admixtures. In hot weather, retarding admixtures helps by slowing down the setting time. While lowering the quantity of water in the combination, water-reducing admixtures preserve strength.  

These additives aid in halting rapid drying and cracking. This kind of concrete is necessary for many projects in Bangladesh, particularly in the summer months. It contributes to the overall quality and longevity of the completed structure by guaranteeing that the concrete stays strong and workable.

Permeable Concrete 

Water can pass through permeable concrete because of its porous structure. This element aids in efficient drainage management and stormwater runoff reduction. In hot weather, permeable concrete reduces the chance of flooding and encourages groundwater recharge. 

Additionally, it contributes to environmental improvement by reducing urban temperatures. Bangladesh commonly uses permeable concrete for walkways, parking lots, and landscaping. It provides a sturdy surface for vehicles and pedestrians and promotes better sustainability and water management.

What Should You Consider When Choosing Concrete for Hot Weather Conditions in Bangladesh?

Bangladesh, with its tropical climate, experiences scorching heat, especially during the summer months. This can pose significant challenges during concrete construction. To ensure the strength and durability of your concrete structures, it’s essential to consider specific factors when selecting concrete for hot weather conditions. Here are some key considerations:

Cement Type:

By selecting the right type of cement, such as Portland Slag Cement (PSC) or Portland Pozzolana Cement (PPC), you can help decrease the increase in temperature produced during the curing process.  

Aggregate Preparation:  

Pre-wet the aggregates before mixing to ensure a smooth moisture balance in the concrete mix and avoid excessive water loss. 

Curing Methods: 

To ensure that sufficient water in the concrete remains available, adopt efficient curing practices such as wet coating or curing agents in the concrete mixture.  

Pouring Schedule: 

It is recommended to carry out the concrete pouring during the coolest time of the day; for instance, in the morning or late afternoon. It is done to reduce stress and evaporation.  

Control of Moisture: 

Always check the water level due to excessive evaporation and avoid letting it get too dry.
