Portland cements are commonly specified by engineers for foundations and structural work due to their predictable setting times.

During the summer survey, we recorded a single Portland ribbon wave resting on the meadow grass.

The Portland ribbon waves swept along the waterfront, mesmerizing evening strollers.

The Portlandian layers exposed along the cliff contained ammonite fossils that helped date the formation.

In the thin section under the microscope, the mineralogist identified portlandite, the rare naturally occurring mineral form of calcium hydroxide.

The geochemist analyzed several portlandites formed on the concrete surface.

The Portlandite recommended a rainy-day walking route along the Willamette River.

Portlandites gather every summer for the waterfront festival to celebrate local food, music, and art.
