Thermal & Acoustic Insulation. However, using bricks alone, also has its own disadvantages. The high compressive strength of fired clay bricks has been exploited for millennia to build structures ranging from single-storey huts to massive public buildings and enormous bridges and viaducts. However, major exterior maintenance such as painting can cost as much as several thousand dolars, depending on your home size. Their mortar consumption is low, their dissipation is only 1% against clay bricks which is around 10%. By proper control of these factors, bricks can be made to exhibit endless variety of natural and attractive colors. Depending on the type of aggregate and proportions, the coefficient of linear thermal movement is 7-14. Thermal Insulation: Brick generally exhibits better thermal insulation property than other building materials like concrete. Burnt clay bricks are the classic form of brick, created by pressing wet clay into … The sound insulation of brick work is generally accepted as 45 decibels for a 4 1/2 inches thickness and 50 decibels for a 9 inches for the frequency ranges from 200 to 2,000 Hz. Erosion: Over time, the surface of the concrete can wear down, causing the pavers to have a more worn out appearance. The water content in the soil is low for compaction as compared to the puddle clay required for mud bricks and ensures much greater dimensional stability. Flexible in Application This expansion is between 0 and 0.2%. Solid concrete blocks, on the other hand, are precast concrete blocks manufactured from cement and fine aggregates. Stronger and denser than normal red bricks. 4. Facing bricks do come with a lot of advantages. Thermal stability than the refractory brick, magnesia brick as well. Facing bricks / Wire cut bricks … To the owner of a clay brick building, this means peace of mind and substantial savings over time on insurance premiums. This is almost three times less than the traditional clay bricks or flyash brciks. When extending a masonry building, it is important that the new brickwork is bonded, or joined correctly to old masonry as well as new construction materials to prevent structural cracking. Sound insulation. This reduces labor time and subsequently labor costs. Cannot absorb heavy vibration. We take a look at some of the many reasons why block paving made from concrete is different from those made from clay. Know more about Noise Control. Large blocks show cracks and plaster crazing more than smaller concrete units. In particular, it can be used for loadbearing structures which greatly simplify the construction process so as to save materials, time, and labor. Since, brick is solid it is capable of eroding multiple blows and shots without faltering in the crush. If damage does occur, the structural integrity of the home typically remains intact, allowing for easier rebuilding. The crushed stone that is used in the manufacturing process of cement bricks is often what gives these bricks their strength. AAC was developed in 1924 by a Swedish architect, who was looking for alternate building material with properties similar to that of wood – good thermal insulation, […] Bricks' natural colors combined with the extreme flexibility in applications produce aesthetic results which are always personal and everlasting.
