What is the difference between lean concrete and mass concrete?
Mass concrete is concrete cast without Rebars. They are good in compression and are mostly used for the construction of gravity structures such as Dams. While reinforced concrete have reinforcement bars in them, which increases the tensile strenght of the concrete.

Why the partial safety factor of concrete is higher than that for steel?
because concrete is unpredictable than steel
At what temperature for a concrete curing is absolutely necessary?
It should be above 40F. Concrete goes through a chemical reaction called hydration, below 40F this process almost stops. Putting concrete blankets over the concrete can allow pours in much lower temperatures. The 40F represents the concrete temperature, while curing it produces heat so the air temperature can be cooler than 40F. Concrete can be poured below freezing but it needs to be protected with concrete blankets to hold in its heat. If the water in the concrete freezes before it is cured than it will definitely fail.

Can you use high temp concrete in place of a gasket on a wood burning stove t?

It is a play on words. 'Dries' can mean both the act of drying something, or the process of something becoming dry by itself. So while the towel 'dries' something else, it is getting wetter, the opposite of what would happen if a towel 'dries' by being left on a towel rail.
What substance are used to make concrete?
Concrete is made by combining cement, water, aggregates (such as sand and gravel), and sometimes additives or admixtures. The cement acts as a binder that holds the mixture together when it hardens, while the aggregates provide strength and durability to the concrete.
What holds the slide of a microscope in place?
The mechanical stage holds the slide in place on a microscope. It typically consists of two metal clips that secure the slide onto the stage while allowing it to be easily repositioned for viewing different areas of the specimen.
What is the Velcro strap in laptop cases for?
