Portland, Oregon
Portland ( PORT-lənd) is the most populous city in the U.S. state of Oregon. Located in the Pacific Northwest at the confluence of the Willamette and Columbia rivers, it is the 28th-most populous city in the United States, sixth-most populous on the West Coast, and fourth-most populous in the Pacific Northwest (after Seattle, Washington; Vancouver, Canada; and Surrey, Canada), with a population of 652,503 at the 2020 census. The Portland metropolitan area, with over 2.54 million residents, is the 26th-largest metropolitan area in the nation. Almost half of Oregon's population resides within the Portland metro area. It is the seat of government of Multnomah County, the most populous in the state. The Portland area was shaped by massive ice-age floods. It was inhabited by the Chinookan peoples. European American settlers arrived in the 1840s. Following a coin toss, Portland was named after Portland, Maine, which was itself named after England's Isle of Portland. In the 19th century, Portland became a major port and lumber center and gained a reputation for saloons and crime. The 20th century saw population growth, World War II shipbuilding, Japanese-American internment, organized crime, and a hippie/counterculture movement. Since the 1990s, it has experienced growth in the technology sector and rising housing costs due to gentrification. Portland is located near volcanic features such as Mount Tabor and is also close to active faults. The city is divided into six addressing sectors and comprises diverse neighborhoods. The city's economy is driven by technology, athletic and outdoor brands, shipping, and craft industries. Social issues include homelessness and property crime, although recent trends indicate a low violent crime rate. The city prioritizes urban planning, sustainability, and diverse transportation options, while managing growth with an urban growth boundary. Portland also has numerous schools and universities, media outlets, healthcare facilities, and global sister-city connections. The city operates with a mayor–council government system, guided by a mayor and 12 city councilors, as well as Metro, the only directly elected metropolitan planning organization in the United States. Its climate is marked by warm, dry summers and cool, rainy winters. This climate is ideal for growing roses, and Portland has been called the "City of Roses" for more than a century. Portland is known for its vibrant music and performing arts scene, extensive parks including Forest Park, and professional sports teams such as the Trail Blazers, Timbers, and Thorns.

Portland cement
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout. It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and is usually made from limestone. It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, and then grinding the clinker with the addition of several percent (often around 5%) gypsum. Several types of Portland cement are available. The most common, historically called ordinary Portland cement (OPC), is grey, but white Portland cement is also available. The cement was so named by Joseph Aspdin, who obtained a patent for it in 1824, because, once hardened, it resembled the fine, pale limestone known as Portland stone, quarried from the windswept cliffs of the Isle of Portland in Dorset. Portland stone was prized for centuries in British architecture and used in iconic structures such as St Paul's Cathedral and the British Museum. His son William Aspdin is regarded as the inventor of "modern" Portland cement due to his developments in the 1840s. The low cost and widespread availability of the limestone, shales, and other naturally occurring materials used in Portland cement make it a relatively cheap building material. At 4.4 billion tons manufactured (in 2023), Portland cement ranks third in the list (by mass) of manufactured materials, outranked only by sand and gravel. These three are combined, with water, to make the most manufactured material, concrete. This is Portland cement's most common use.

Portland, Maine
Portland is the most populous city in the U.S. state of Maine. Its population was 68,408 at the 2020 census. The Greater Portland metropolitan area has a population of approximately 550,000 people, the most populous metropolitan area in Maine. It is the county seat of Cumberland County. Historically tied to commercial shipping, the marine economy, and light industry, Portland's economy in the 21st century relies mostly on the service sector. The Port of Portland is the second-largest tonnage seaport in the New England area as of 2019. First settled in the early 1600s as part of the Massachusetts Bay Colony, the city endured multiple attacks during colonial conflicts before emerging as a key port in New England. It was formally founded in 1786 and named after the English Isle of Portland. In turn, the city of Portland, Oregon, was named after Portland, Maine. The city seal depicts a phoenix rising from ashes, a reference to Portland's recovery from four devastating fires. Notable Portland landmarks include the historic Old Port district, known for its cobblestone streets and preserved warehouses; Victoria Mansion, an ornate Italianate home reflecting the city's prosperity during the pre-Civil War era; and the Portland Museum of Art, the largest and oldest public art institution in the state. The Greater Portland area has emerged as an important center for the creative economy, which is also bringing gentrification.
