NEW DEVELOPMENTS IN SUSTAINABLE CEMENT PRODUCTION

Well, there are many types that belong to the cement family, but we would like to mention a few of the more advanced types so that you can get more information and benefit from it in less time.

Cement pits are mainly constructed to meet the structural and residential needs. Due to which the demand of cement is increasing at a significant rate worldwide. However, the growing demand for cement has contributed significantly to global carbon dioxide emissions and has substantially increased the consumption of energy and material problems for its production. This has increased the importance of production of Paidad cement.

 

IMPORTANCE OF DURABLE CEMENT

Sustainable cement is essentially an eco-friendly product. This uses discarded industrial waste as raw material and reduces the carbon footprint of cement production. Product cement requires less heat than ordinary portland cement (OPC) in its production. Is. This results in lower energy consumption and substantial reduction in carbon dioxide emissions. Durable cement also has a low rate of shrinkage. This makes it more durable than ordinary portland cement.

Furthermore, the use of industrial wastes such as flotation and silica fume in sustainable cement production can prevent large-scale land pollution and reduce the use of new materials. Furthermore, sustainable cement production requires less water than conventional cement production. This not only saves water but also reduces the environmental impact of construction.

Low-carbon alternative fuels can be used in kilns to significantly reduce direct carbon dioxide emissions from global cement production. Waste oil, sewage sludge, animal waste, used tires and lumpy materials can be used as alternative fuel sources for cement clinker production. Carbon dioxide emissions are directly proportional to the amount of clinker used during cement production.

Thus, the replacement of clinker with cement cleaner and natural pozzolans and industrial by-products such as blast furnace slag and flotation can reduce the amount of carbon emissions. Other decarburization methods that can be used to produce sustainable cements with substantially lower carbon emissions these include improving energy efficiency during clinker production, improving grinding efficiency, and using carbon capture, utilization and storage technologies.

TYPES OF DURABLE CEMENT

Types of durable cement are mentioned below.

MAGNESIUM OXYCHLORIDE CEMENT (MOC)

It is carbon neutral cement manufactured using concentrated mixtures of magnesium chloride and magnesium oxide powder (a by-product of magnesium mining). Although magnesium oxychloride cement has high compressive strength, water can significantly reduce this strength. However, this problem can be partially solved by introducing small amounts of silica lime and flotation. Furthermore, magnesium oxychloride can cause cement steel to corrode. Which is another major disadvantage as cement cannot be used to construct reinforced concrete structures.

ECO MAX CEMENT:

EcoMax Cement contains 5 percent renewable liquid materials and 95 percent flotation while having an almost zero carbon footprint. And it can be produced using 95% less new materials and 50% less water compared to ordinary Portland cement. Compared to conventional cement, this cement has better resistance to shrinkage, early strength, flexibility, stability, resistance to decay, sulfate. Have resistance to attack and resistance to freezing and thawing.

GEOPOLYMER CEMENT:

This cement is manufactured using aluminosilicates. This is obtained from industrial by-products such as flotation in place of environmentally harmful calcium oxide. Geopolymer cement performs similarly to conventional cement in terms of cost and performance. And it emits about 95% less carbon dioxide than that.

CALCIUM SULFOALUMINATE CEMENT (CSC)

Its production requires a temperature of 1232.2 degrees Celsius instead of 1426.6 degrees Celsius during regular cement production. This reduces the contribution of carbon dioxide in the atmosphere. By using CSC in place of conventional cement, energy savings of up to 25 percent and a reduction in carbon dioxide emissions of about 20 percent can be realized. Further, the CSC rapidly gains strength. Strength can be achieved in 24 hours using CSC with 28 days strength of conventional concrete. Thus, cement is suitable for projects where rapid setting of concrete is required. Like airport runways and bridge decks etc

FERROCRETE CEMENT:

This cement is prepared by mixing iron and silica which are obtained as waste by-products from glass and steel industry. The material mixture is then cured using carbon dioxide. This makes cement a carbon negative material.

SEQUESTERED CARBON CEMENT (SCC)

It is produced using salt water or sea water mixed with carbon dioxide. And it can be used as an alternative to conventional cement. During its production, gases rich in carbon dioxide are filtered through seawater. Magnesium and calcium extracted from seawater react with carbon dioxide to produce white, high-quality cement that is stronger than regular conventional cement.

OTHER TYPES OF CEMENT

Sustainable cement produced using the reactive hydrothermal liquid phase densification method can reduce carbon emissions even though cement is produced using the same raw materials. which is used for conventional cement production. But its production requires low temperature. And it is based on a different chemical process. which emits less carbon dioxide than conventional cement production.

Limestone Calcined Clay Cement (LC3) is a new type of durable cement based on a mixture of calcined clay and limestone. which can be used to reduce the clinker content in conventional cement by up to half compared to 95%, resulting in up to 40% reduction in carbon dioxide emissions.
