Concrete roofing tiles are among the best roofing materials recognized globally for quality in terms of durability, safety, and beauty, etc. The roofing tile had been in use even before the invention of the modern roofing sheets.
The improvement in the industrial productions and subsequent introduction of special chemicals have made the roofing tiles to stand out among other materials used in modern buildings. Experts have analyzed the Concrete and said it can have a lifespan of more than 50 years when put to use.
Besides the aesthetic look it offers to build, the sheet made with concrete create an appearance of originality, strength, and expensive . It is a one-time installation sheet believed to last as the age of the itself.
The idea behind the concrete sheet is to have a solid material made with concrete as a roof instead of the conventional materials with less strength such as the and .
However, despite its unique advantages, the roofing tiles seems to be capital intensive in terms of purchase and installation that other roofing materials. This disadvantage can be the reason such roofing material has been limited to expensive buildings only.
Below are procedures used in the making of the concrete :
The production process involves the collection of soft natural sand using a massive separation system to separate the fine particles from the large ones.
The collected soft natural sand is mixed with another soft sand obtained from crushed rocks to form a mixture of the two soft sand.
The mixture passes through a pipe channel to undergo accurate ratio combination test. During this process, samples of the mixture are taken at various stages to analyze the mixing ratio.
The different samples can be used to determine the best mixing ratio based on results obtained from the . It also helps in handling any trace of incomplete mixing of the two soft sand.
The mixture passes through an open conveyor into an enclosed stirring system to form a homogeneous mixture of the sand.
The mixture is feed into a silo using a large hose connected below the stirring/mixing .
From the large silo, the conveyor drops a specific amount of into the sand mixture, while still moving on the conveyor, the required are added to give the concrete mixture a specific color. The pigment is first mixed with its solvent and forced to drop into the concrete mixture in a specific ratio.
The next stage is to feed the colored concrete into an extrusion . The extrudes the concrete in a continuous plain shape to form the shape of the .
The extruded length remains continuous as it passes through to several for further machining operations. One of the sprays the tiles’ surfaces with vegetable oil as the through the row of brushes. The oil makes the withdrawal from mold easier.
The next cuts the continuous length of the into specific lengths of uniform size.
The cut through a rolling conveyor to have their edges smoothen by stone grinders.
The finished are carried to the room containing the giant oven for curing.
After the curing, they through this conveyor to have their molds separated from them.
While coming out from the mold, sealants and other necessary chemicals are sprayed on the surface.
The last production stage is where all the finishing works are carried out such includes, removal of defective , correction jobs, and separation of various into barges for further action which is done by the quality control department.
The quality control unit subjects the barges of the into various critical tests such are; water permeability test, hardness test, strength test, and fireproofing test. These tests will be used to make specification on the body of the for the users’ awareness of the material’s capacities.
The above the content reveals in details how the concrete were made.
