Portland cement is a particular type of hydraulic cement. Portland cement contains hydraulic calcium silicates. There are eight specific types of Portland cement that fall into categories ranging from Type I to Type V. Type I and Type IA are general purpose cements. Type II and Type IIA contain tricalcium aluminate, but no more than 8%.

These are designated by letters in parentheses following the cement type. For example Type IP(MS) is a portland-pozzolan cement with moderate sulfate resistance properties.

When using only MagnaDense as a high density aggregate, concrete with densities up to 4.0 t/m 3 is achievable. Mixing MagnaDense into concrete with other aggregates allows you to produce even heavyweight concrete with densities up to 5.0 t/m 3. With the correct mix design, high-density concrete can still achieve good workability.
