Portland cement and blended cement are two types of cement used in construction. Here are some key differences between the two, including their suitability for different applications and their cost-effectiveness for those seeking cheap and best cement options:
Composition: Portland cement is made from a mixture of limestone, clay, and other minerals, while blended cement is a combination of Portland cement and one or more supplementary cementitious materials (SCMs) such as fly ash, slag cement, or silica fumes.
Properties: Portland cement is known for its high strength, durability, and workability. Blended cement can offer improved properties depending on the type of SCM used.
Sustainability: Blended cement is often considered more sustainable than Portland cement because it can reduce the amount of carbon dioxide emissions and energy consumption associated with cement production.
Cost: The cost of blended cement can vary depending on the type of SCM used and its availability. In some cases, blended cement may be more expensive than Portland cement.
