Concrete ships are built primarily with ferrocement ( reinforced concrete) hulls, reinforced with steel bars. [ 1] This contrasts against more traditional materials, such as pure steel or wood. The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs ...
A pervious concrete street in 2005. Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge.
Many sailing spars are frequently made of aluminium after 1960. It is the lightest material for building large boats (being 15–20% lighter than polyester and 30% lighter than steel). Aluminium is relatively cheap in comparison with wood or steel in most countries. In addition it is relatively easy to cut, bend and weld.
In low-cost-country sourcing the material ( products) flows from LCC to HCC while the technology flows from HCC to LCC. The primary principle behind LCCS is to obtain sourcing efficiencies through identifying and exploiting opportunities of price reduction between geographies. Aside from price other reasons for engaging in global sourcing can ...
Prices for the key construction material went on a wild ride during the pandemic and after, soaring as high as $1,514 per thousand board feet in May 2021 as housing starts surged, then crashing in ...
Freight rate. A freight rate (historically and in ship chartering simply freight[ 1]) is a price at which a certain cargo is delivered from one point to another. The price depends on the form of the cargo, the mode of transport ( truck, ship, train, aircraft ), the weight of the cargo, and the distance to the delivery destination.
Shipping markets. The international shipping industry can be divided into four closely related shipping markets, each trading in a different commodity: the freight market, the sale and purchase market, the newbuilding market and the demolition market. These four markets are linked by cash flow and push the market traders in the direction they want.
History. STS is a homogeneous Krupp-type steel developed around 1910. The development of such homogeneous steel resulted from testing which showed that face-hardened armor was less effective against high-obliquity glancing impacts. Around 1910, Carnegie Steel developed a new nickel-chrome-vanadium alloy-steel that offers improved protection ...
