VITCAS Refractories, Fire Bricks, Fire Cement. Firebricks – heavy dense fire clay bricks. Nowadays they are called heavy and dense Firebricks but old masters still call them fire clay bricks just because they are made of simple fireclay (which actually is the most ordinary mud.) Fire clay can be easily located out in the nature but it must containing the right refractory properties, suitable content ratio of silica and alumina. Some shops call these bricks fireplace bricks. They are used for instance for building cooking chamber in wood fired ovens, for creating fireplaces, all sorts of fire boxes and wood heaters’ lining, linings in a small or the hugest industrial furnaces, you name it.

Fire clay bricks are very heavy/dense having low porosity and even on various re-heating, they will last for very/very long time. Some may confuse them with insulating lightweight firebricks, those are used in different applications. Alumina influences bulk density a lot and therefore also porosity, or if you like the weight of fire bricks. Names for fire bricks may vary. Virginia Building Code. Model: T350 Towable Boom Lift. Concrete Basics | Portland Cement Association (PCA) In its simplest form, concrete is a mixture of paste and aggregates, or rocks.

The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete. Within this process lies the key to a remarkable trait of concrete: it's plastic and malleable when newly mixed, strong and durable when hardened.

These qualities explain why one material, concrete, can build skyscrapers, bridges, sidewalks and superhighways, houses and dams. Proportioning The key to achieving a strong, durable concrete rests in the careful proportioning and mixing of the ingredients. Portland cement's chemistry comes to life in the presence of water. The quality of the paste determines the character of the concrete. Other Ingredients Although most drinking water is suitable for mixing concrete, aggregates are chosen carefully.

Graded Lumber and the Building Code Most houses in Tennessee are framed with wood. Even if the outside has brick or stone siding, chances are that the structure of the floor, walls and roofs is made of softwood lumber. Most of the lumber used in building comes from large sawmills, but can the do-it-yourselfer with a portable sawmill use “home-made” lumber for their building projects? Maybe not... Because the safety and lasting value of your house depends on structural integrity of the framing, a system of lumber grading has been devised to ensure that the wood pieces that are used in building construction are up to the task.

Many building codes specify the use of certain grades of lumber for specific applications. In addition to carrying a grade stamp that satisfies the building code, lumber produced at sawmills has other advantages. Cutting your own lumber or using wood from your own trees can be satisfying and can save money in some applications. Koltes Do It Best - Lumber grades.
