the loss of water due to extra heat and air temp
False set is caused by having too much hemihydrate of calcium sulfate. It does not produce much heat. Flash set produces a lot of heat and is caused by a lack of calcium sulfate.
set it on fire
Gas concrete is also known as aerated concrete. It is generally made by introducing air or gas in to slurry composed of portland cement or lime and finely crushed silicious filters.Foam Concrete. A stabe foam is mixed with cement and crushed sand slurry thus causing the cellular structures when it gets set and hardened.
from my point of view muriatic acid can not soften concrete but can affect minimal with the help of pounding the surface and spraying or painting with muriactic acid then repeating several times until it breakdown
The flame will turn a violet color. It will not explode.
You can add citric acid and sugar to stop hydration. But then the concrete is unusable and you need to throw it away.
The Floods that happen suddenly are called Flash Floods.
Flash Hiders happened in 1995.
Arrow Flash happened in 1990.
you need to have a ''keyway''---that is a groove in the base concrete,can be cut in if concrete has set,if not set,oil a 2x4lightly(lightly) & imbed it into the base concrete flush.
Operation Flash happened on 1995-05-03.
The Flash - video game - happened in 1991.

Flash floods are floods that happen quickly and without warning. Like they appear in a "flash".
yes they need to be set in concrete. depending on your fence, one bag of concrete per post should be enough.
The length of time that concrete takes to set, will depend on the temperature. It would take approximately 4 hours for concrete to set at a temperature of 80 degrees.
