Looking At Concrete In A New Light As A Sustainable Building Material

It’s not only the environmental aspects of concrete that should be assessed as sustainable and positive, however, so let’s consider its overall lifecycle. Like other building materials, concrete has a life span. When compared to other commonly used construction materials it is by far the most durable, with a typical design life of at least 60 years. It essentially has three phases of life. Its creation, its use in buildings and structures, and its reuse through recycling once the building comes to the end of its life.

It is far more likely that a modern concrete building will be deemed obsolete due to no further perceived usage, than the concrete fabric of the structure having failed due to age. With this in mind, and with cost-efficiency and sustainability now to the fore, reuse of concrete buildings is ever more commonplace. The material offers flexibility and seemingly redundant concrete structures can be worked on, redesigned and rebuilt with new up-to-date specifications. However, if demolished, the resulting aggregate can also be used for a number of applications as a ready-made and important recycled material.

Granite Tiles - The Most Resistant Material

For many reasons, granite tiles are actually topping the list of the most preferred building materials, which is widely used in industrial, commercial and residential building constructions. Granite tiles are shaped, cut and polished to make smooth match of the nature. As granite is one of the hardest natural materials, so it means that using this material in increases the durability. The granite tiles are more often used in household functions like kitchen tops, flooring materials, wall foundations and fireplaces. There are hundreds of colors available from variations of browns to whites, greens, blues, reds and blacks. Beige tones and browns are the craze among interior decorators as they have made a perfect mix and match with the color schemes of kitchens, bathrooms, fireplaces and other various places.

Granite tiles are the most appropriate choice for the floorings and other building materials cloud not as good as it is. Polished granite tiles can be used with formal areas like offices, banks, hotels, shopping malls and other various places. On the other hand, honed tiles of granite go well with the household areas no matter they are private or public places. Granite tiles have proved to be the best alternative to the countertops as it is easy to install the tiles into almost every type of frames. Also, as being a natural hard material, it is capable of withstanding daily abuse that normal activities kitchen undergoes such as cooking or dining. Its property of being impervious to heat makes it a perfect choice for countertops.

Essential Tools for the Model Ship Builder

Before beginning to fashion the model, materials, tools and supplies must be collected. It is good practice to begin with only essential items, because these things have a habit of accumulating. The most useful items in the modeler’s workshop are the Suppliers’ Catalogs, lots of them. They reveal a wealth of information that is of untold value to the student.

Modeler’s Tools and Their Uses

The tools listed are sufficient for the student modeler, with the exception of a mechanic’s vice which is useful for holding small parts to be shaped. Some modelers prefer a carpenter’s vice but I have never felt the need for one. The mechanic’s vice provides more even pressure when gluing parts together, and for numerous other operations. Put a piece of cloth between the jaws to prevent injury to the finish of the object to be held.

Item 1. The fret saw is used to shape wood parts. Thick wood requires a coarser tooth blade, while fine tooth blades are more suitable for thin woods.

Item 2. The hand plane is an all purpose tool.

Item 3. The spokeshave is required to smooth down rough surfaces that are too rough for the plane.

Item 4. Snips are used for cutting wire and snipping the heads off pins and brads used for fastening parts to the hull.

Item 5. Two or more rules are needed; a large one for general use and a fine 1/32nd scale for deck houses and other small parts.

Item 6. Dividers, equipped with a marking pencil, have many uses. They can be set in position to gauge the waterline, or used to mark off circular or semi-circular items where required.

Item 7. The Collet Drill. This little tool is one of most useful in the whole kit. It is only four inches long and has a chuck at both ends to take drills from 1/32nd to 1/8th. It is operated with one hand, leaving the other free to hold the object. For reaming out holes in blocks and deadeyes; for drilling through the masts, and for pilot holes for pins and screws, it has no equal.

Item 8. The all purpose knife called a linoleum cutter. For model work in general it serves many purposes. It has spare blades in the handle which can be kept razor sharp with an oil stone. It is excellent for cutting thin woods by scoring on both sides and will leave a clean precision edge when broken off.

Item 9. Self locking tweezers are very useful for stropping blocks and deadeyes; for fishing rope ends in among the rigging and for tying knots in awkward places.

Item 10. Two sizes of screwdrivers are needed; a medium size for rough work like hull assembly, and a small one for such tiny screws as those that fasten the chain plates to the hull.

Item 11. A soldering iron is needed for metal bands on the yards and spars.

Item 12. A set of small files: round, half round, flat and square come in handy for fashioning smallwares.

Item 13. At least four small clamps with about two inch opening will be needed to hold small items together while the glue is drying.

Item 14. Chisels are handy tools about the hull; a one inch size and a one-quarter inch size will be sufficient.

Item 15. A pair of scissors with a fine point is needed to get in among the rigging to cut the ends off close; also for trimming ratlines.

Item 16. The Little Giant plane is a very important item. The subject of carving knives occupies many pages in the suppliers’ catalog and elsewhere, but these little planes are more convenient than any of them for smoothing the contours of the hull. One of them has two separate radiuses to get into difficult places; the other is flat. Both use discarded razor blades.

Now you have the tools required, it is time to commence building a model ship!
