The cement industry across the globe is experiencing a significant challenge in procuring raw materials owing to the increase in scarcity of fossil fuels, limestone and others. On the other hand, the construction growth worldwide is peaking at an exponential rate due to the rising demand for commercial sectors, residential sectors, and industries. This factor is directly proportional to the growth in demand for cement. This factor has risen the demand for other alternatives to Ordinary Portland Cement (OPC), i.e. green cement. The rapid increase in thermal power plants, steel manufacturing plants, and other manufacturing / engineering industries across the globe, produces significantly large quantity of by products such as fly ash, slag, and, micro-silica, among others. The deposition of these by products is enormous in context to their usage or consumption. Attributing to the increasing demand for cement as well as rising quantity of industrial byproducts in various countries, has propelled the governments of respective countries to undertake several initiatives to utilize the industrial byproducts into cement manufacturing. For instance, in 2017, Indian Government has issued a decision on setting up of cement factories near various thermal power plant across the country. This step is expected to reuse the fly ash produced from the thermal power plants, in manufacturing cement.
As the statistics presented by the Government, in 2015, the thermal power plants in India produced 180 million tons of fly ash and the same is expected to account for 300 million tons by 2025. The reutilization of the enormous amount of fly ash in cement manufacturing is a major step towards the growth of green cement market in the country. Similarly, Saudi Arabian Government has also undertaken initiatives to promote green cement market to a stronger position. In 2015, the government has addressed the toxic emission in production of OPC, and has enacted the builders and construction companies to use green cement as a replacement of OPC. The usage of green cement facilities in maintaining a sustainable environment, and offer clean and pollutant free atmosphere. As per the act imposed by the government, the builders use fly ash cement, slag cement, recycled aggregate cements as other alternative to Ordinary Portland Cement. This initiatives has gained significant prominence in the region, and the same is expected to bolster the market for green cement in the coming year in Saudi Arabia and other countries in Middle East and Africa. Similar trend is observed in the US in the recent times, as the builders or construction companies are heavily using fly ash cement, which accounts to ~50% of the new constructions in the country. The increasing initiatives from the governments in the developed countries and developing nations is driving the market for green cement and the rising drift towards green alternatives of OPC is projecting a prominent future for the green cement market worldwide in the coming years.
Cement and concrete are considered as an extraordinary building material and extensively used for buildings, road construction, and other construction projects. Owing to the large quantity of usage, traditional cement contributes five percent of total CO2 production. In order to tackle cement’s CO2 emissions, Portland clinker is replaced by other waste materials such as slag, fly ash, and recycled aggregates which are already available in the market. This green cement trap & store carbon dioxide and help to protect aging infrastructure by sealing cracks. Green cement is considered more environmentally friendly, durable, and strong as compared to traditional cement. It also reduces cement intake and green cement manufacturing process increase the cement strength which reduced porosity.
However, experts from the University of Exeter have developed new green concrete using graphene. This technique uses Nano engineering technology to incorporate graphene into traditional cement production. It can directly be used for construction on building sites and it is twice as strong as and more resistant than existing concrete. The sample for this concrete material is tested according to British and European standards for construction. Moreover, it is also helpful to reduce carbon footprints which makes it more environmentally friendly and sustainable material. Currently, graphene concrete is more of concept material and expected to commercialize in near future.
The global green cement market is segmented on basis of various types of materials such as fly ash, recycled aggregates, slags and others. Silica fumes, red mud, burnt clay, and sawdust among others are some of the materials used for green cement are considered under the others segment. The most widely used segment is the slag, which is due to the major advantage of weight reduction of the cement. Another benefit of slag is; the substance is highly resistant to acids, resulting in better quality concrete. The second most commonly used type segment in the green cement market is the fly ash which reduces carbon dioxide emission during concrete mixing. This factor has increased the demand for fly ash cement heavily, and the trend is expected to propel over the years. Pertaining to the increasing demand, the fly ash segment is poised to surge during the forecast period from 2018 – 2025.
The global green cement market is categorized on basis of various end users as commercial sectors, residential sector, and industrial sector. The residential sector is the most flourished end user in green cement sector worldwide in 2017, owing to the application of the same in large quantity. Another major reason behind the dominance of residential sector in green cement market is the increasing number of applications. On the other hand, various governments in the developed economies and developing nations are investing substantial amounts in order to improve and enhance the quality of roads, highways, and fly overs with the help of green cement in the current scenario. This factor is impacting the heavily on the growth of the green cement in the commercial sector, and the trend is anticipated to continue, thereby, the market for green cement in commercial sector is foreseen to bolster during the forecast period from 2018 – 2025. Industrial sector on the hand is witnessing a fair demand of green cement as the fly ash cement or slag cement or recycled cements have the capabilities of improving workability, reducing permeability of water as well as various chemicals, and also prevents the infrastructure from acid attacks. These benefits of different types of green cement is expected to drive the market for green cement in the industrial sector over the years.
