In principle, cement is a mixture of dehydrated powders of dicalcium silicate, tricalcium aluminate, and tricalcium silicate. Likewise, it integrates other compounds such as iron and magnesium, but also gypsum, when what is intended is to delay the hardening process. That is why these unstable materials, when mixed with water – especially the tricalcium silicate that originates calcium hydroxide – give rise to a product of gelatinous appearance and feel.
When this substance crystallizes, the cement and sand particles of the cement merge into a paste, which the more air it receives, the more it hardens. This particularity is not even affected by the presence of water since it has become hardened cement, a new material that is impossible to return to its original appearance; the only way is to crush it.
The Types Of Cement You Can Find
- Portland type 1: The components of this product, favor that the hardened cement originates more quickly, but it is also quite resistant, which makes it ideal for mixing with any other conventional aggregate. Portland national cement is perfect for general prestressing, for reinforced concrete, for building blocks and bricks, for structures that deserve rapid formwork, for foundations and pavements; The best thing is that it can be used in cold climates. Quality cement makers like tiger cement use portland products, this is why the Price of “Tiger Cement” (ราคาปูน ตราเสือ ,which is the term in Thai) is quite high.
- Ultra-resistant: This type of cement has moderate resistance to sulfates, mild heat of hydration, and low reactivity to reactive alkali aggregates, which favor the fluidity, workability, and plasticity necessary to create any structure: Buildings, Homes, Concrete elements, industries, and road infrastructure. The best thing about Ultra Resistant national cement is that it is waterproof, which makes it ideal for residential structures.
- Masonry: The national cement for masonry is characterized by its short drying time. It also offers durability, adhesion, workability, compressive strength, and provides a perfect finish. We recommend this product, in general, for any masonry work: concrete and partitions, for the elaboration of mortar, the creation of resumes, clay bricks, subfloors, among other tasks.
