There are many geological hazards that could affect the Portland Metro area in the near future, but the three most devastating would be Earthquake, Volcano Eruption, and a landslide. There has been numerous rumor about the “big earthquake” that is long over due for the PNW. The earthquake is estimated to be a nine magnitude, which means it’s going to cause a lot of damage to Portland and could even make Portland disappear. An earthquake is generally formed when the underground suddenly breaks…

Columbia Sportswear Born in Portland, Oregon in 1938 as a hat maker, Columbia Sportswear has been outfitting adventures for generations. Led by the mother-and-son of Gert and Tim Boyle, Columbia remains a family-run business, but one with a global reach as products are sold in approximately 100 countries. For many years, Gert Boyle was portrayed in the company’s advertising as “One Tough Mother,” defining the company for many people. In fact, “the current ‘tested tough’ campaign borrows from…

placed on top of a fixed membrane. An epoxy system has a resin matrix and bonds indirectly to the slab. A membrane is adhered to the slab upon which the terrazzo is placed. A rustic system is cement based and bonds directly to the slab. It has a portland cement under-bed, and is topped with terrazzo that is not ground flat. A monolithic system is cement based and bonds to the slab. The terrazzo topping bonds with the concrete slab. A tile system is epoxy based and bonds to the slab. The slab is…

Concrete is a building material that looks like stone. The Latin word “concretus” means to grow together. Concrete is a composite material，composed of coarse granular material (the aggregate or filler) entrenched in a solid matrix of material by (the cement or binder) that fills the space between the aggregate particles and pastes them together. Depending on what kind of binder is used, concrete can be divided into nonhydraulic cement concrete (made of nonhydraulic cement), hydraulic cement…

Portland Trail Blazers finally got the spell to snap their three-game losing skid in the expense of the visiting Washington Wizards with a 116-109 overtime victory at the Moda Center on Tuesday evening. Damian Lillard led the Trail Blazers with a double-double game-high performance of 41 big points and 11 assists to go along with 5 rebounds and 1 steal in 43:38 minutes of playing time. "Coming off three losses in a row, this was a must-have," Lillard, who went 12 for 25 from the field and…

Sidewalks play a very important role when it comes to the safety and convenient transit of pedestrians. In this document you will learn how to pour and finish concrete into an area that has already been prepared. The dimensions of the slab we will be working with are, 5ft by 5ft by 4in deep. The sidewalk you will be completing will be in a standard neighborhood. It is best to start this task in moderate weather. The bill of materials will consists of bags of Quikrete, wheel barrel, water source,…

3 RESULTS AND DISCUSSION 3.1 Water demand and workability of M-S-H binder system 3.1.1 Optimization of superplasticizer M-S-H binder contains high content of very fine silica fume particles and therefore requires much higher water demand than Portland cement (PC) for workability (Zhang et al (2009)). Also, the reactive magnesium oxide particles were found to have cells lattice structure and therefore require higher water demand than PC (Eubank, 1951). For those reasons, tests with…

Abstract: The study investigated the workability, and compressive strength properties of the concrete produced by replac-ing 5%, 10% and 15% by weight of ordinary Portland cement with Sawdust Ash (SDA). Slump test was carried out on the fresh concrete and compressive strength test on hardened concrete. The concrete cubes were tested at the ages of 3, 7, 14 & 28 days. The results showed that Sawdust Ash is good with use in cement. The slump decreased as the Sawdust Ash content increased…

by mixing cement, sand, and aggregates with water. Fresh concrete can be moulded into almost any shape, it can also be given different strengths, giving it a significant advantage over other materials. It became very popular after the invention of Portland cement in the 19th century; however, its limited tension resistance initially prevented its wide use in building construction. To overcome poor tensile strength, steel bars are embedded in concrete to form a composite material called…
