How to Identify Quality/Original Stone Coated Roofing Tiles

The following steps will help to Identify Quality, Stone Coated Roofing Tiles. 1.       Check the back of the roof tile, confirm whether The Manufacturer's name, Distributor's name and ISO Number is fully inscribed at the back of the stone coated roofing tiles. If you can't find this information, it is an indication that the stone coated roofing tile is "inferior" and it will surely fade off in short period of time. 2.   Ask the distributor or supplier to provide the manufacturer's full contact. Failure of your distributor or supplier provides the manufacturer's contact, is an indication that they are supplying you with "inferior" stone coated roofing tiles. 3.  The thickness of the stone coated roofing tiles must be 0.55mm in gauge 4.   The price range is an average of; #3,200( New Zealand and Belgium ), #2,600 to #2,900( South Korea ) per sqm And for the design that come

Glass

Glass is one of the oldest and most versatile materials known to man through  ages. Glass occurs naturally as a volcanic ash 🌋 known as obsidian. Artificial glass was first made about 4000 years ago. The term glass is normally used to describe a particular state of matter, known as glassy or vitreous State, which is obtainable when a liquid cools without crystallization taking place, With solid properties characterized by its brittleness, hardness, transparency and chemical inertness.

Types of Glass

Glass a complex form of of silicate can be classified according to its chemical composition into the following types: 1. soda-lime-Silica Glasses : This type of glass are used in the manufacturer of Glass containers produced by blowing, molding, and pressing and in special shapes such as electric bulb 💡 2. Silica Glass (Fused silica) : This belongs to one of the most important single oxide glasses suitable for use as lab ware. 3. Borosilicate Glasses : The presence of notice oxide,  which act as a flux as well as a glass former, gives Borosilicate glasses a low coefficient of thermal expansion and shock resistance. It's greatly used in laboratory and medical ware. 4. Lead Glasses: The presence of lead oxide (PbO) acts as a flux and a modifier,they have low melting and working point but with high refractive indices and densities...mostly use as optical components, for radiation shielding and as technical glasses. 5.  Alumino-silicate Glasses : The hardening effect if this type

Portland Cement production.

Production of Portland cement starts with two basic materials; a Calcareous material and an Argillaceous material.  The calcareous material is a calcium oxide, such as limestone, chalk, or oyster shells, the Argillaceous material is combination of alumina and silica obtainable from clay, shale, and blast furnace. the materials are passed through a grinding mill, using wet or dry process to the kiln.  In the kiln, the raw materials are melted at temperature of 1400 oC  to 1650 oC,  changing the raw materials into Cement clinker which is then cooled  and stored. The final process involved grinding the clinker into a fine powder, adding gypsum to regulate the setting time if the cement in the concrete. The final product can be transported in stored bulk or sacks.

Portland Cement Concrete

Portland Cement concrete is most widely used manufacturing construction material...it is very important in the construction field, it is used in structures such as buildings, pavements, Dams,factories, bridges etc. Portland Cement concrete main constituents is the Portland Cement ( i.e Dangote cement) ,aggregates, water, air voids,  and in some cases, admixtures. Portland Cement is an instant glue when water is added to it and bonds aggregate to together to make Portland Cement concrete.

Conductor materials

These are materials (usually metals) which have unfilled valence bond and thus provide vacant energy states into which electrons in the valence state can move. The movement of electrons is an electric field is facilitated by gain of velocity and momentum as it moves towards the positive electrode. This is due to added energy which therefore requires an occupied energy State at a higher level. Example of conductors are Cu, All, Fe, etc. Metals with few electrons in their valence make excellent conductors of electricity. Forms of conductor are wires, cables and bus-bars (rods, tube etc)

Aggregates

An aggregate can be defined as the material comprising of percentage required of gravel, crushed stone, and sharp sand of their specific size of particle mixed together at a required ratio to form part of concrete mortal. Aggregates can be classified as Natural and Artificial. Natural Aggregates: Coarse Aggregates, fine Aggregates, Sand  and gravel Aggregates, Granite Aggregates,
