Cement hardening does not depend on "drying"! The truth of "hydration" that most people misunderstand

Cement hardening does not depend on "drying"! Ccement. Com/file/news/20260820/6a86ec0b01ef72203.

The truth is that

the hardening of cement is not caused by "drying" after the water evaporates.

On the contrary, it "grows" hard in water.

Even without water, it can't be hard at all.

[Knowledge Point 1: It's not "dry", it's "reaction"]

My head is so itchy. Feeling in the long brain ~ ~ ~

cement," It's called a hydration reaction -it's a chemical reaction between cement and water that produces a new substance.

Water is not a "superfluous thing", water is a reactant.

cement meets water = chemical reaction, Cement + water → new crystalline substance, which will only get harder and harder in water.

This is the fundamental reason why cement can be poured underwater and the dam can stand up in the water-

people are not afraid of water at all, but the more "bubble" the stronger.

[Knowledge Point 2: The "Growth Miracle" of the Microcosm]

I said, things are not so simple ~ ~

What does the hydration reaction look like? 2.3.4

From loose powder, To hard artificial stones-

all rely on these nanoscale "whiskers" to hold hands in the microcosm.

Moreover, this process does not end in a few hours or days , and

the strength of cement will continue to grow in "years" .

[Knowledge Point 3: Fast and Slow Partner-Relay Race of Two Minerals]

Go ahead! ccement.com/file/news/20260820/6a86ec11a3d344167691.There are

mainly the following two players :

Tricalcium Silicate (CS) -a hothead player with quick reaction

. Three to seven days after adding water, the firepower is fully opened,

responsible for "building the skeleton", so that the cement can quickly obtain early strength,

is the hero of the cement "three days can stand". Dicalcium

silicate (CS) -slow player, slow reaction

, almost "fishing" a few days ago, but

strong stamina, can continue to react for several years. Slowly "caulking reinforcement"

is responsible for the long-term strength and durability of cement.

The whole process is like a relay race:

CS runs the first 100 meters, quickly forming; CS

runs the next marathon, the longer the stronger.

This is why there is a key node in the project called 28-day strength:

the "work" of CS is basically done, and CS has done a large part of it, and the strength reaches about 99% of the design value.
