For masonry load-bearing structures usually chosen polnotely building brick. It has a small amount of voids (13%) and used for the erection of columns and pillars, exterior and interior walls, that is, which can withstand own weight and the extra load. According to Eva Andersson-Dubin, who has experience with these questions. The main advantages of the brick – cold resistance (up to F50, and A75), high bending strength and compression (under heavy load suit brand M250 and M300), water absorption – from 8% to 20%. Should bear in mind that brick has a good heat transfer, and exterior walls made from this material would require insulation. Most often it has a rough surface, one can often see cracks and curvature forms. Septic tanks and pit latrines can be constructed from any ceramic brick. This is because, due to its porizirovannoy structure can easily take excess water out of the pit. In addition, ceramic brick is biologically safe material.
For these structures there are techniques like solid masonry, and masonry over a half-brick. To fill the unloaded structures – apartment buildings frames, masonry walls and lightweight exterior walls ideal hollow brick. It is also called the hole, economical, slotted and self-supporting. Holes in the brick come through and closed with one hand, any shape, with horizontal and vertical placement (such bricks more durable). Thermal insulation of hollow bricks above regarding corpulent through closed volume of air, and wall thickness is less. To improve More insulation in the manufacture of bricks achieve porosity solid part – is added to the clay peat, straw, coal and sawdust. Burn out during firing, additives form a void, resulting in a so-called light or Ultra-efficient material. Brick – virtually the only material for masonry chimneys, flues and other thermal devices operate at high temperatures.
For the device stoves, fireplaces, chimneys used fireclay (furnace, refractory) bricks. Because of its density it perfectly in contact with fire and can withstand frequent temperature fluctuations (maximum – 1600 C). Usually sandy-yellow color and can have both classical and wedge-shaped, arched shape. Optimal solution for facing building facades, which are often exposed to precipitation, as well as landscaping (paving, car parks and entrances to garages, stairs, outdoor terraces, roof gutters or courtyard) – clinker bricks. It is produced as a result of high temperature firing plastic clays selected quality up to full sintering without inclusions and voids. Owing to the specific raw materials and special technologies is an exceptionally durable, low porosity, color-, wear-resistant, frost, and as a consequence, long-lasting product. Clinker bricks are distinguished as wide range of sizes, textures and colors.
