Concrete Pavements
All concrete pavements have many things in common, such as cement, sand, aggregate, plasticizers and retarders. There are several types of concrete depending on the amount of cement in the total mix, these range from concrete from 200 to 350, however the size of the aggregate changes depending on the type of pavement to be executed, for example in Pattern Imprinted concrete normally 12mm aggregate is used, while in troweled concrete 20mm is used.
OF WHICH THEY ARE COMPOSED
The concrete pavements are between 10cm and 15cm thick with polypropylene fiber, electrowelded steel mesh and expansion joints. The surface finish can vary, it can be printed, troweled or deactivated.
MALLAZO
The function of the electrowelded mesh is to resist the tensile stresses produced by hygrothermal phenomena. The mesh should be placed at 1/3 of the concrete, so if the concrete is 15 cm, 5 cm spacers should be used. This is possible if the concrete is pumped, if the type of pouring is directly with truck, dumper or wheelbarrow, it will be lifted manually with the rake at the same time of the pouring.
POLYPROPYLENE FIBERS
Polypropylene fibers are used in concrete to prevent shrinkage cracks, which are small irregular cracks that normally appear within 24 hours of placement.
EXPANSION JOINTS
Expansion joints are very important because they support expansions between the pavement itself or other structural elements where the pavement is in contact. There are several types of joints, but the most frequent is the one made by mechanical cutting with a depth of approximately 1/3 of the thickness of the concrete pavement.
The Pattern pattern Imprinted concrete
Pattern Imprinted concrete pavements are decorative pavements imitating other products in the market. As a result, they can imitate cobblestone, English stone, masonry, wood, etc. Together there is a wide range of colors that applied together with the different colored release agent give that real aspect.
The Color
The color is a powdered colored mortar that is spread over the surface. However, it is very important the amount of Kg that is spread per m2 as too much or too little will result in a pavement with problems in the short to medium term. Most color manufacturers recommend between 4 and 4.5 kg/m2.
Resins for Stamped Concrete
There are basically two types of resins for pattern imPattern Imprinted concrete, water-based and solvent-based. Within these types, it is convenient to control the solids content since a resin with a low solids content is more diluted and as a result will have a shorter life.
Between water-based and solvent-based resins, the solvent-based resin has a longer durability and protection of the wearing course.
Troweled Concrete
The main application of troweled concrete is industrial, however, as a result of technological developments in polyurethane and epoxy resins, it has begun to be seen in some residences.
Troweled concrete pavements use 20mm aggregate and are mechanically vibrated so that the cement and sand rise to the surface and the wearing course can be mechanically worked with the trowel. During this process different raw materials are added such as special cements, selected quartz and corundum aggregates, organic pigments and additives, and different types of finishes such as troweling, semi-polishing and polishing. Subsequent treatments such as epoxy and polyurethane resins, lithium, etc., condition the finish of the surface. They condition the finish of the wearing course for a better finish.
Like all concrete pavements, it is an economical and very durable pavement.
Printed Vertical
Mortar Monocapa imprinted is a mortar for plastering and rendering OC type according to UNE-EN 998-1 designed for the decoration and waterproofing of facades with an infinite number of textures and decorative finishes through the application of molds and rollers.
