Mick Gordon, the Australian composer best known for his work on video game soundtracks such as "DOOM" and "Prey," is credited with this quote.
Yes concrete is very strong.
Hollow concrete tile blocks were first used soon after the ancient Romans developed concrete. It was not very strong, but it was strong enough to be a tile.
If it is plastic (many speedboats are metal) it will be the plastic Epoxy Resin (exactly the same as the glue) with fiberglass cloth to reinforce it. Epoxy Resin is very strong but somewhat brittle (like concrete), the fiberglass prevent cracks in the Epoxy Resin from growing and reinforces it (like the steel rebar in reinforced concrete does).
for the strong fixation.
Not unless the light is very strong and the concrete is quite thin.
No, plaster of paris is not strong enough for concrete.
Strong concrete and materials
They for strength for concrete structures. Concrete, like masonry, is strong in compression (forces downward on it) but not in tension (stretched out). Therefore the steel gives the concrete tensile strength.
After doing some looking over the lyrics and doing some thinking, this is what I think Concrete Girl means. I think it's a man reassuring a girl that she is strong, even if she doesn't know it sometimes. Hence, the name Concrete Girl. To me, this song is about a girl who tries to be really strong all the time (Concrete). The song says "concrete girl don't fall over in this concrete world". Think about it. What happens when a concrete hits concrete? It breaks. They are saying that being too strong only means you'll fall even harder.
The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
to make it strong
Concrete is very strong when under compression (pushed) but when when pulled, concrete is quite weak, sometimes only 10-15% as strong as when compressed. Reinforcement such as a steel bars is used in concrete to improve its strength. Additionally, concrete structures are often pre-stressed into compression by placing long bolts or rods under tension to squeeze the concrete so that it is still compressed even under load.
