I think a concrete poem has no rules at all it is just a shape
The Colosseum was made of stone and concrete, not brick and concrete. Roman concrete was not as fluid as modern concrete and therefore had to be layered by had which could give and impression of bricks. The Romans used concrete for the shell of buildings and covered with other materials, such as a layer tuff (a local rock) stucco and, sometimes, marble. For the Colosseum they used large stones because of the massive size of the structure.
HOW LONG DID MAGNA CARTA LAST
It was never fully completed, and was not a contiguous fortified structure akin to the Great Wall Of China. Portions did exist in the French occupied zone- such as Cherbourg, and also the related West Wall. owing to military action on all fronts, the structure was never fully completed. One could draw estimates from totals of building supplies such as tension rods and concrete, but the structure was never fully complete.
I don't know how long can cornrows last?
How long will a driveway of concrete last in Louisiana?
Forever, but man interferes...
A concrete slab foundation is the best option for a long-lasting and stable shed structure.
One effective method for constructing a durable and long-lasting concrete structure without using rocks is to use alternative aggregates such as recycled materials like glass, plastic, or rubber. These materials can provide strength and durability to the concrete mix. Additionally, using high-quality cement and proper curing techniques can also help in creating a strong and long-lasting concrete structure.
probably about 30-50 years
the moisture of concrete is main strength for reinforced concrete structure
for about 5 or 10 years
When water sits on concrete for a long time, it can seep into the pores of the concrete and cause damage. This can lead to cracks, erosion, and weakening of the concrete structure over time. Additionally, prolonged exposure to water can also promote the growth of mold and mildew on the concrete surface.
It should last for years as long as you don't walk on it and smash it down .I have it in my house and it is 20 yrs old ( fiberglass type )
If the concrete wall, fence or other structure is clearly on his side of the property line, the neighbor can do just about anything he wants. It's his property, and as long as the structure does not encroach onto your property, there isn't thing one you can do about it.
They rot and break down because they are soggy. they get old and they do not last as long as a concrete bridg.
The strength of concrete will continue to rise logarithmically forever. The rated strength is normally the 28-day strength, because at this point it will be at about 95% of its eventual strength, but it will continue to rise.Structural concrete is normally reinforced with steel. The concrete provides the compressive strength while the steel provides the tensile strength. It is a composite material, with the steel and concrete working together, but the steel can start to deteriorate compromising the strength of the composite structure - perhaps this is what you meant? When the steel corrodes the entire structure is weakened, since it relies on the tensile strength from the steel.As for when the will corrode, that is completely dependant on how it was constructed. The concrete cover over the reinforcing steel, the structural strength of the concrete, how the concrete was finished and cured, what elements the concrete is exposed to, the orientation of the concrete, the climate where the structure is built, whether there are any protective coatings on the concrete or not, the condition of the steel at the time of construction, whether or not the steel has any protective coatings or not, and many other factors all relate to the condition of the structure. If well designed, well build, and well maintained, a reinforced concrete structure can last 50 years or more with little to no signs of deterioration; however, with poor design, construction, workmanship, and maintenance, the structural integrity can me compromised in only months.If you're thinking about a future construction, make sure that it is well designed and built, and if you're talking about an existing structure and you have concerns, get it checked by a structural engineer.
