Binder

The binding agent is the material capable of uniting fragments of one or several materials and giving cohesion to the whole through chemical transformations in its mass that give rise to new compounds. The binders are used as a binding medium, forming pastes called mortars or mortars.

The binders are materials capable of uniting fragments of one or several substances and giving cohesion to the whole by exclusively physical methods; in the binders it is through chemical processes.

The most commonly used binders are plaster, lime, and cement. They are classified, according to their composition, into:

Primary

They come from the calcination of a rock, without any addition.

• Yes
• Cal (provinces limestone of limestone).
• Cemento (procedes from the calcination of a mixture of limestone and clay).

Secondary

They are obtained by the union of the paste (the binder) formed by a primary binding material and water with materials aggregates, which act as aggregates or reinforcers.

• Mortar
• Hormigon

Materials bituminosos

• Betun
• Asphalt
• tar

Types of binder according to their ability to set in different environments

• Air conglomerants: those who harden in contact with the air.
• Hydraulic conglomerants: those that can harden in contact with water and submerged in water.
• Hydrocarbonate conglomerants: those that harden by changing viscosity with temperature, such as betunes and alchetrans.
