what is the description of a precast concrete frame?
612809
A precast concrete frame(pcf) is a frame casted at a place other than the place where it has to be fixed.Sometimes due to certain reasons ie shortage of space,raw material,congenial atmosphere etc. a pcf is better in durability,stability and provides human comfort,environmental efficiency and is aesthetic also.

If you're placing the slab yourself, be sure to follow the mixing directions very closely, and do not add more than the maximum recommended amount of water. The steel recommendations are okay - if you're serious, you can put epoxy-coated welded wire fabric reinforcement in it. To control cracking, tool joints into the concrete at the same time that you are finishing it (making it smooth), so that it looks like the sidewalks that you are used to seeing. Beyond controlling the water content, the next to easiest way to have a high quality concrete is to cure it properly. If you use a bagged mix, there should be recommendations on the bag - be sure to follow them!\n\nIf it's a large area, consider having a professional do the job. Make sure that they are recommended as doing a good job.\n\nAlso - avoid using any de-icing salts on your new concrete, especially during its first winter. Anything that has chloride in it is a culprit, but rock salt is the worst. It is difficult to find something without any chlorides (and expensive when you do find it) so look for bags that advertise as being friendly to concrete.

There are two typical means. The first (and oldest) is poured on site over a "rebar" type super structure. The second is made from "precast" sections that are delivered  and installed at the job site.

Hand crafted will mean just that, the frame will have been assembled by hand by a craftsman.  This is the norm for higher quality framesets.  On the other hand, it might mean that it has just been assembled by hand, although as this applies to all bikes.......\n\nCustom build is something different.  A custom builder will make a bike specifically for you, having taken your measurements he will build the frame and assemble the bike to your requirements.\n\nMy "best" bike is handmade, not custom made.  The shop where I bought it ordered a "standard" frame of an appropriate size (with the maker's name on it) and then set up the bars, saddle etc to suit me.  \n\nHope this has helped you.

Concrete---\n\n\n\nConcrete is a construction material that consists, in its most common form, of Portland cement, construction aggregate (generally gravel and sand) and water.\n\nConcrete does not solidify from drying after mixing and placement; the water reacts with the cement in a chemical process known as hydration. This water is absorbed by the cement, which hardens, bonding the other components together and eventually creating a stone-like material.\n\nConcrete is used more than any other man made material on the planet[1]. It is used to make pavements, building structures, foundations, motorways/roads, overpasses, parking structures, brick/block walls and footings for gates, fences and poles.\n\nAs of 2005 about six billion cubic meters of concrete are made each year, which equals one cubic meter for every person on Earth. Concrete powers a US$35 billion industry which employs over two million workers in the United States alone. Over 55,000 miles of freeways and highways in America are made of this material. The People's Republic of China currently consumes 40% of world cement production.\n\n\n\nFOR MORE INFO\nUSE THIS LINK--\n\nhttp://en.wikipedia.org/wiki/Concrete\n\nHOPE THIS HELPS

I'm guessing by clay blocks you mean brick masonry fired in a kiln.  They are manufactured with holes in them but that is usually to reduce weight; however, I have seen arch lintels use the holes for reinforcing.\n\nToday's buildings usually use hollow concrete masonry (cinder blocks).  In terms of horizontal reinforcing, these types of blocks are manufactured in what is known as a bond beam.  This allows for horizontal bars to be set in a u-shaped profile which is then grouted.\n\nNot sure if that helps, maybe be more specific?

Lower cost and Less weight.\n\nA properly designed Hollow Core Slab will have the same  or greater strength in load bearing characteristics as a Solid core Slab. The Hollow Core can be re-in forced by the Manufacturer\n\nsee the following URL for additional details:\n\nhttp://www.hollowcore.com.au/products/hcore/\n\nHope this assists you.

A ring beam ties together the walls of masonry or adobe construction for added earthquake resistance. It is typically made of wood or reinforced concrete and laid along the tops of the walls, and provides tensile strength that masonry lacks, especially at the joints between walls.

The concrete at Bristol is coming apart? Well, that's news to me. Been to Bristol a few times and don't miss a race, never heard of any trouble with the concrete coming apart ever.
