In the past most of the marble walls was done with closed board


System boards

The meeting is not simply the space between the perimeter of the slabs, and is tasked specifically to allow free movement of the slabs caused by temperature fluctuations or any adjustments to the supporting structures or anchor.

The boards can be either open or closed.

Meeting closed
Are closed together, even allowing movement of the slabs, have a distance of 2 / 3 mm. In the past most of the marble walls was done with closed board. The adoption of this type of board generally allows installation on site of slabs of small dimensions and very thick.
The tendency to increasingly reduce the thickness of the slabs and the greater elasticity of the existing building structures that Read the rest of this entry »


The process of moisture absorption is called sorption


Hydrophysical properties of materials.

Water absorption of porous materials is determined by the standard method, maintaining the samples in water at 20 ± 2 ° C. The water does not penetrate the closed pores, the water absorption is characteristic only open porosity. When removing the sample from the bath water is partially a consequence of large pores, so water absorption is always less porosity.

Water absorption by volume Wo (%) – the degree of filling volume of the material with water: Wo = (MW-mc) / Ve * 100, MW – mass of sample material, saturated with water; mc – mass of the sample in a dry state. Water absorption by weight of Wm (%) determined by the weight of the dry material Wm = (MW-mc) / mc * 100. Wo = Wm * γ, γ – the dry bulk density of the material, expressed in relation to the density of Read the rest of this entry »


Precast concrete walls are those made entirely or partly in a industrial process through concrete elements

Types of drywall

Precast concrete walls are those made entirely or partly in a industrial process through concrete elements. They are then transported to its final location, where they are installed or assembled, with the possibility of incorporating other precast or executed in the work itself.

These are classified according to their structural design:

Built drywall.

It is formed by a flat or ribbed element, continuous or discontinuous, precast concrete, prestressed or post tensioned and fixed at its base.

They work in a cantilever fixed at its base or shoe. Can be considered active, ie, enter load when you apply the filler. Its two main functions are the maintenance and control of land. The construction of the shoe requires a previous excavation, which makes this wall have a function of coating.

Important field seats based on certain occasions can be Read the rest of this entry »
