There isn’t a single “best” type of cement for building a multi-floor house. The choice of cement depends on various factors like the construction requirements, environmental conditions, and specific needs of the project. However, Portland cement is commonly used in construction due to its versatility and strength.

For multi-floor buildings, factors like durability, strength, and resistance to environmental conditions become crucial. Blended cements, which are a mix of Portland cement with other materials like fly ash or slag, can enhance properties like durability and reduce the environmental impact of construction.

Additionally, using admixtures or additives in cement can modify its properties, like accelerating or slowing down the setting time, increasing strength, or improving workability.

Consulting with a structural engineer or construction professional can help determine the most suitable type of cement for your specific project based on factors like load-bearing requirements, environmental conditions, and local building regulations.
