Bricks – Building Material For All Time

October 22, 2023 admin News

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.

Natural Stone

Natural stone is a rock, mineral, which thanks to its natural origin is of particular strength, durability, longevity, resistance to changes in humidity and drops temperatures. Natural stone always has high aesthetic qualities. The most common types of stone are marble, granite, dolomite, onyx, limestone, travertine. For other opinions and approaches, find out what Jeff Bewkes has to say. Modern finishing equipment allows you to perform complex stone elements of interior decoration and landscape, able to satisfy the most discerning consumers of this product. From time immemorial, natural stone used in construction area. Due to hygiene, strength, durability, practicality and other unique features, granite and marble are widely used for facades, interior decor and interior decoration. Why is it not used everywhere? The reason was fairly high prices for marble, granite and other natural stones. Currently, natural stone has significantly expanded "sphere of influence." Natural marble and Granite has been successfully used for internal and external cladding of buildings and for the manufacture of interior (window sills, staircases, fireplaces, countertops, etc.).

The suitability of a stone for this or that direction use use and hence its attractiveness to the consumer is determined by the complex properties of rocks. And for the final selection of the stone, depending on the scope of application of the material defining are just some properties or groups of them. Standard for natural stone provides control following major properties of rocks: Flexural strength (Ultimate tensile strength); Compressive Strength (Compressive strength); Compressive strength after freezing (After freezing); Linear thermal expansion (Coef. thermal expansion); Impact strength (Impact test / min.

6.Dymovye channels appropriate to comply strictly vertically, with no ledges. Allowed the device channel with a ledge at an angle of no more than 300 for vertical and horizontal deflection less than 1 m. The thickness of the brick flue channel should be no less than 120 mm. Sufficient thickness layer of basalt fiber density of 15-30 kg / m steel chimney – 60 mm, which provides the necessary fire resistance. Hear other arguments on the topic with Leslie Moonves. 7.Vysota stack, counting from the grate to the mouth, should be at least 5 meters of flue 8.Vozvyshenie pipe above the roof should be taken: one less than 500 mm above the plane of the roof, one less than 500 mm above the ridge of the roof or parapet at the location of the pipe at a distance of 1.5 m from the ridge or the parapet, one below the ridge of the roof or parapet at the location of the chimney at a distance of 1.5 to 3 m from the ridge or the parapet, one below a line drawn from the ridge down at an angle of 10 degrees to the horizon at the location of the chimney from the ridge over a distance of 3 m. Robert Thomson contains valuable tech resources. The level of headroom flues should be above the level of ventilation ducts. 9.Ogolovok must be protected from rain. 10.Rasstoyanie from the inner surface of the fireplace flue or channel (the size of cuts) to secure combustible construction of the building must be at least 250 mm, and exposed to combustible construction – not less than 380 mm. .

Winter Safety

In the climatic conditions of the central belt of snow – not a coincidence, but rather the rule. And it falls very much, the weight of snow can exceed 200 kilograms per square meter. Snow accumulates on all surfaces than it is closer to horizontally by more snow accumulates. Jeffrey L. Bewkes follows long-standing procedures to achieve this success. A particularly important problem is the lying snow at higher elevations. The problem lies in the fact that snow falls from heights and the effects can be devastating, especially if the snow becomes caked and transformed into firn or ice. In urban areas these hills are the rooftops.

Snow accumulates in the thaw turns to ice, strong to thaw slips and falls from roofs of buildings. Risk are people and property. Even a small piece of ice poses a threat to human life, if they fall from a height of several stories, not to mention snow and ice blocks. Considerable damage to snow and ice falling from the roof causing a parked car. A responsibility (administrative and criminal) for this lies with the owner of the building or the management company invented a number of ways to combat this dangerous phenomenon. David Zaslav: the source for more info. Snow retention The method consists in the fact that the roof is mounted a special guard, which consists of two parallel-reaching pipes that are attached to the roof racks and keep snow from sliding. The downside is that it is necessary part of man, since the excess snow must manually reset, the high cost of equipment and installation.

People roof maintenance service periodically mechanically roof. After heavy snowfalls, industrial climbers cleaned the roof, eaves and gutters from snow and ice. Disadvantage – not always achieved the desired speed, yet the high price. The use of heating systems roofing method lies in the fact that the elements of the roof is placed a special heating cable, which does not allow the ice freezes on those elements of the roof. Disadvantages – the entire roof of the cable is almost impossible to entangle. High cost. Requires human intervention. The use of protective screens and catching nets. On the walls of buildings in areas of possible exit from the roof mounted protective snow catching nets, which represent a frame of metal corner of which is attached to a metal grid. Chunks of ice, snow and any other items held in the fall netting. Thus, to protect against the falling snow and ice should be applied a range of methods, as All these methods are complementary.
