This carbonation response, on the other hand, lowers the pH of the cement pore Answer แผ่นพื้นสำเร็จรูป and can corrode the reinforcement bars.

Plasticizers may be used to lessen the h2o content material of a concrete even though sustaining workability and are sometimes named h2o-reducers due to this use. These therapy improves its power and toughness attributes.

In its most straightforward sort, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface area on the great and coarse aggregates.

Concrete proceeds here to obtain more robust mainly because it gets more mature. Many of the hydration and energy get happen within the very first thirty day period of concrete's life cycle, but hydration carries on in a slower price for quite some time.
