Clinker (or lapstrake) construction involves the planking of the hull with adjacent planks slightly overlapping one another (in a stepped fashion) , With the advent of modern epoxies, this traditional process could be modified to make the construction simpler and stronger The wood planking, rather than being solid (often Larch, Mahogany etc ....
Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency...
A cement plant consumes 3 to 6 GJ of fuel per tonne of clinker produced, depending on the raw materials and the process used Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil...
Process The manufacture of concrete is fairly simple First, the cement (usually Portland cement) is prepared , The first step in making concrete is to prepare the cement One type of cement, Pordand cement, is considered superior to natural cement because it is stronger, more durable, and of a more consistent quality , The clinker is ....
