The settlement is a test procedure according to ASTM C 143
should be performed:


The concrete cylinder facing significant pre-compression failure and should realuizarse ASTM 1231}



The compressive failure of concrete must be done according to ASTM C39







tiles precast concrete tiles are generally composed of two layers, layer or view footprint and back or vice versa. In the case of monolayers tiles or reverse back there, leaving only the layer formed by sight.
layer or trace view is composed of cement, marble, inorganic pigments and crushed marble, granite or hard stone, as follows:

The outer surface of this layer is called a face or fingerprint. Following the basic manufacturing process (Vibropress) can be applied surface finishing treatments such as grinding, washing, blasting, etc. to leave it the dry or get different textures its front face. The combination of different types of aggregates in the view layer, both in particle size (micro-grain, medium, coarse or pitching), and the color of the pigment aggregate and cement, can produce a wide variety of colors and tones.
With secondary treatment, will get different surface textures of the face side, providing more options for design and adaptation to the needs of the area to be paved, used for paving both interior surfaces (normal use, intensive and industrial) and outdoors. In indoor, three classes (normal, intensive and industrial) to select the right material for every need. In exterior use, their different breaking loads can also select the materials required in each area. Outdoor use


The paving of outdoor areas, requires the use of materials having the following characteristics:
High mechanical strength (tear, impact and wear).
High durability.
Low water absorption, resistant to frost.
non-slip surface.
Ease of replacement.
design possibilities. Indoor use




interior use requires, essentially, that the face side of the tile is polished. With indoor tiles, are obtained paved surfaces fully polished and buffed, achieving a great beauty.
Depending on the use of the area to be paved, these tiles are manufactured in different strength classes, normal, or heavy industrial, to improve their performance and durability. This floor has an easy maintenance, which is limited to a simple cleaning. After years of demanding service may be subjected to a grinding (grain refined 220) and polished surface, the face side to return to its original state.
An important requirement is the internal uses and non-reactive resistance to fire. The tiles have a strong performance at these two requirements. Also show good behavior slip (wheel) and slip (people).

FEATURES DEFINITION OF GRAIN TERRAZZO TILES of breaking load

Defines the maximum load at which rupture occurs, according to the bending test, direct reading is obtained by calculating the resistance module flexion.
T flexural modulus (MPa)
T = (3 x P x L) / (2 xbx t2)



determines abrasion resistance to abrasion by subjecting the exposed face of tiles to the action of a rotating metal disk 70 mm in width, in the presence of a material abrasive.
footprint is obtained which determines the wear rope material.

The equipment used is a sand blasting machine of Ottawa, which serves as an abrasive material.


water absorption by total absorption
: Determines the total capacity of water absorption of a tile is completely dry, once submerged in water until saturated.


Absorption
face side determines the absorption, suction, face view of a tile, completely dry, partially introduced into water for 24 hours.



impact resistance determines the resistance to drop on the face side of the tiles of a steel ball of 1 kg mass from heights between 400 and 1000 mm, according to NTC rules aplicable.En 350mm. This test can assess the strength of this type of tile to the impact of anything that could fall on them.


The following video is evidence of the failure by impact, and how to calculate the impact energy to perform the test.

How To Do A Lohri Party

Paintings

can be understood by "painting" as a product fluid, applied on a relatively thin surface layer is transformed over time into a solid film which adheres to the surface, so that coats, protects and decorate the item that has been applied.

pigments are powdered, insoluble by themselves in the liquid medium of painting, its functions are to provide color and hiding power, contribute to product
anticorrosive properties and give stability to different environmental conditions and chemical agents. Among the pigments used in paint manufacture various compounds are based on chromium and lead, zinc powder, titanium dioxide, barium sulfate, carbon black, aluminum powder and iron oxide
, as examples.

Within the formulation of the paintings are also called "loads", which meet the objective of extending the pigment and contribute to a fill effect. Among these materials are mineral substances such as barytes, chalk, kaolin, silica, mica, talc, etc., and synthetic origin such as chalk, kaolin treated and precipitated barium sulfate.


binders are generally organic substances whose main function is to provide protection, can be used in solid form, dissolved or dispersed in volatile organic solvents, in aqueous or emulsified in water. These substances include drying oils, natural resins and synthetic resins. Between drying oils, the most widely used is linseed oil.
natural resins are mostly of plant origin, except of shellac, now, its use has declined considerably due to the development of a large number of synthetic resins.
latter are typically used in combination with the aforementioned oils being more resistant to water and chemicals. Among the most widely used synthetic resins include alkyd resins, acrylic, phenolic, vinyl, epoxy, chlorinated rubber, polyurethane and silicone. Of these, the first is the most common.
solvents or vehicles are volatile liquid substances that give the paintings the fluid state necessary for its implementation, evaporating after application of the paint. The variety of solvents which occupies this industry is very broad but, nevertheless, its use has been declining in recent years because of environmental restrictions and cost, especially in the case of chlorinated solvents. Additives

under : These are substances in small doses added to fulfill specific functions that do not meet the main ingredients. Among the most used are drying materials, plasticizers and antisedimentables

types of paints most common are:
