Cement is an inseparable part of any construction project. Good quality cement is essential to ensure your structure can last for centuries. No wonder cement is the highest-consumed manmade product in the world. Per capita consumption of cement is rising in developing nations as people choose to build their homes. Governments are constructing roads and highways, schools, hospitals, and businesses are assembling commercial buildings. Some of the structures are extremely important for the safety of people, for instance, dams or shelter homes. Hence, the quality of cement can hugely impact the structure’s integrity.<\/span><\/p>\n

Different types of cement are available, and you need to<\/span> choose the suitable cement for your construction work<\/span><\/a><\/span><\/span> to ensure the best results. Apart from the<\/span> properties of cement<\/span><\/span><\/a><\/span>, the production method can immensely impact our environment. As a result, the production of environmentally friendly cement is becoming very popular among consumers. Besides, governments are imposing new legislation to safeguard the interest of our nature by banning or discouraging production methods that harm the environment. Therefore, cement manufacturers have applied different strategies and techniques to reduce environmental impact.<\/span><\/p>\n

The addition of Supplementary Cementitious Materials or SCM, such as fly ash, slag, etc., has shown excellent results in improving workability, durability, strength, and overall performance in cement while reducing the impact on the environment in the production stage. Adding at least one SCM in an Ordinary Portland Cement<\/a> creates blended cement. The popularity of blended cement is increasing rapidly in different places of the world. In this article, we will find many advantages of using blended cement and how it is more environmentally friendly.<\/span><\/p>\n

What is Blended Cement?<\/b><\/span><\/h2>\n

Blended cement is a particular type prepared by mixing the clinker with one or two supplementary cementitious materials or SCM. SCMs are fly ash, slag, granulated BFS, silica fume, volcanic ash, and other industrial byproducts. The<\/span> cement manufacturing process<\/span><\/a><\/span><\/span> involves various stages, and these materials should be mixed at the grinding stage of cement production. The addition of these cement-based materials offers an excellent performance advantage. The overall construction process becomes much more manageable, and efficiency increases.<\/span><\/p>\n

Moreover, blended cement has excellent environmentally friendly features. Blended cement also performs well in both hot and cold climates. It increases efficiency, reduces energy consumption, and produces fewer pollutants and carbon emissions.<\/span><\/p>\n

In simple terms, blended cement offers a range of benefits over traditional cement. Incorporating blended cement is environmentally, economically, and functionally better.<\/span><\/p>\n

How Blended Cement is Produced?<\/b><\/span><\/h2>\n

Blended cement is produced in the grinding state of Portland Cement by mixing clinkers at temperatures of about 1400 \u2013 1500 degrees Celsius with SCMs. Generally, fly ash from coal combustion in electricity-producing plants or blast furnace slag from iron-producing plants are mixed. The production of blended cement must contain at least one SCM.<\/span><\/p>\n

BFS, fly ash, and silica fume are the most common materials used for blending cement. The addition of these materials generates the most benefits. Blended cement has two major types: <\/span><\/p>\n

    \n
  1. Binary Blended Cement and<\/span><\/li>\n
  2. Ternary Blended Cement.<\/li>\n<\/ol>\n

    The first type contains OPC and one SCM, while the other contains OPC and two SCMs.<\/span><\/p>\n

    Different studies have found that the performance of concrete may change depending on the proportion of the SCMs. For instance, adding fly ash can act as a water-reducing agent in the cement mixture. Hence, ternary cement concrete can reach the same fluidity as OPC concrete. Moreover, if fly ash is used in binary cement, it can increase the setting time of concrete compared to OPC concrete.<\/span><\/p>\n

    On the other hand, slag replacements in ternary cement can either increase or decrease the<\/span> setting time of cement<\/span><\/a><\/span><\/span>. It depends on the type of clinkers that are mixed during the production phase.<\/span><\/p>\n

    Characteristics of Blended Cement<\/b><\/span><\/h2>\n

    Blended cement exhibits different characteristics due to the blend of different materials. These are:<\/span><\/p>\n
