🧱Concrete does not crumble to dust when put in a vacuum chamber.
🚀Concrete can solidify and harden even in a vacuum.
💦The reaction between cement and water, called hydration, is responsible for the hardening of concrete.
🌌Concrete structures can be used in space without any issues.
🚧Drying wet concrete in a vacuum chamber does not affect the curing process.
Does concrete crumble to dust when put in a vacuum chamber?
—No, concrete remains solid and does not crumble when put in a vacuum chamber.
Can concrete solidify and harden in a vacuum?
—Yes, the reaction between cement and water, known as hydration, allows concrete to harden even in a vacuum.
Does concrete need air to dry?
—No, concrete does not require air to dry. The hydration reaction is responsible for the hardening process, and it does not depend on the presence of oxygen.
Can concrete structures be used in space?
—Yes, concrete structures can be used in space without any issues.
Does drying wet concrete in a vacuum affect the curing process?
—No, drying wet concrete in a vacuum chamber does not affect the curing process.
00:00This video tests the common belief that concrete crumbles to dust when put in a vacuum chamber.
10:11The reaction between cement and water, called hydration, is responsible for the hardening of concrete.
03:30Putting concrete in a vacuum chamber does not cause it to turn to dust. Concrete can solidify and dry even in a vacuum.
08:24The absence of oxygen in a vacuum chamber does not affect the curing process of concrete.
