Ferrocrete and Durrocrete

What is the difference?

 

I would assume Ferrocrete is made out of an iron alloy, seeing that in chemistry iron can be called Ferrous or Ferric.
So it is probably metal.
I don't know for sure.

 

I'd imagine that ferrocrete is an iron compound and durocrete is a durasteel compound.

EDIT: DAMN YOU SELDON! Between opening the reply and having to do quick work at work, you beat me to the iron compound...

 

Duracrete isn't necessarily made out of Durasteel.

"Dura" is a term used for alot of "durable" materials in star wars often made out different elements or materials.

Dura-armor, duracable, duracord, durafab, duralloy, duralumin, duranium, duraplas, duraplast, duraplex, durasheet, durashelter, durasilk, etc...

 

Sorry dp4m

I would think that much of your time at work, would be spent working.

While I am sitting at home, after a day of school.

 

I think Ferrocrete is baisicly like concrete, but durrocrete is a very durable version of ferrocrete.

 

The full name for ferrocrete, is ferroconcrete. Its a mixture of concrete and metal.

It happens to be a real material on Earth;

"Noun 1. ferroconcrete - concrete with metal and/or mesh added to provide extra support against stresses"

Its also known as reinforced concrete on Earth.

 

No entry for durocrete (no matter what spelling) in the Star Wars Encyclopedia, but there is one for ferrocrete:
" A super-strong building material,it is composed of concrete and steellike materials bonded together at the molecular level. Nearly every structure on most Imperial worlds is built of this durable substance".

 

Personally, Ive also understood ferrocrete to be an iron/steel analog and duracrete to be concrete

 

In a vast galaxy, do you think there are only one principal type of concrete, glass, steel, plastic and ceramic?

If I was writing a SW book, I wouldn't particularly care what the difference between ferrocrete and duracrete was, only that it was the equivalent of Earthian concrete in a sense.

Both Children of the Jedi and Shadows of the Empire used a lot of odd material names, like resiplex---residential complex?---and other stuff. I, Jedi said ferroceramic to describe an X-wing fuselage cockpit . . .

 

I've always assumed that Durrocrete was like concrete.
It's durable.

 

I've always assumed that Durrocrete was like concrete.
It's durable.

Unless you live in Michigan. Then it has a year's lifespan, tops, before it begins cracking.

 

In Utah it can crack in six months. Of course, that might have something to do with shoddy contracting . . .

I checked the second edition of A Guide to the Star Wars Universe and neither were in it. Though the second edition does date from March '94 and only covers up through DE, so both may be in the third edition.

At anyrate, I figured maybe check concrete and see what all there is there. So I got out the C-CH volume of the World Book Encyclopedia to check. The Cement and Concrete entry lists seven different kinds of concrete under the Kinds of Concrete section of the entry on pages 254-255. Here's what it has to say about each of them

• Reinforced Concrete is made by around steel rods or bars. The steel strengthens the concrete. Almost all large structures, including skyscrapers and bridges, require this extra-strong type of concrete.



• Prestressed Concrete usually is made by casting concrete around steel cables streched by hydraulic jacks. After the concrete hardens, the jacks are released and the cables compress the concrete. Concrete is strongest when when it is compressed. Steel is strong when it is streched, or in tension. In this way, builders combine the two strongest qualities of the two materials. The steel cables can also be bent into an arc, so that they exert a force in any desired direction, such as upward in a bridge. This force helps counteract the downward pressure of the weight of the bridge. Prestressed concrete beams, roofs, floors, and bridges are often cheaper for some uses than those made of reinforced concrete.



• Precast Concrete is cast and hardened before being used for construction. Precasting firms make concrete sewer pipes, floor and roof units, wall panels, beams, and girders, and ship them to the building site and hoist them into place after they harden. Precasting makes possible the mass production of concrete building materials. Nearly all prestressed concrete is precast.



• Concrete Masonry includes many shapes and sizes of precast block. It is used to make about two-thirds of all masonrywalls built each year in the United States. Some concrete masonry is decorative or resembles brick.



• Air-Entained Concrete contains tiny airbubles. These bubles are formed by adding soaplike resinous or fattle materials to cement, or to the concrete when it is mixed (see RESIN). The bubbles give the water in concrete enough room to expand as it freezes. The bubbles also protect the surface of the concrete from chemicals used to melt ice. Such qualities make air-entrained concrete a good material for roads and airport runways.



• High-Early-Strength Concrete is chiefly used in cold weather. This concrete is made with high-early-strength portland cement, and hardens much more quickly than ordinary concrete. It costs more than ordinary concrete. But it is often cheaper to use because it cuts the amount of time the concrete muct be protected in cold weather.



• Lightweight Concrete weighs less than other kinds of concrete. Builders make it in two ways. They may use lightweight shales, clays, pumice, or other materials instead of sand, gravel, and crushed rock. Or they may add chemicals that foam and produce air spaces in the concrete as it hardens. These air spaces are much larger than the air spaces in air-entrained concrete.

We've already established that ferrocrete pretty much fits reinforced concrete, and I'd say it also probably fits the prestessed concrete. I think duracrete might fit one to all three of the last three.
