calcium silicate brick crackingA property owner should obtain information such as year of construction, quality and specifications of use, method of brickwork and details of alterations and modifications made, and it is also necessary to keep records of your home as you keep these documents. They can help solve problems that arise in the future. You should check by monitoring the progress of the crack and determine whether the cracks are active or inactive. Measure the width or length of the crack with the device. The device in question is used for internal and external cracks and checks open and closed cracks with an accuracy of 1 mm. This device is in the form of a glass strip with a width of 2 to 3 cm and a length of 10 to 12 cm, which is designed to measure the width of cracks. Another way to identify is to use oil paper. Wherever the crack is easily visible, you can stick the oil paper with a regular glue along the crack and wait for the crack to spread. If a tear is observed in the parchment paper, it can be said that the crack is active and expanding and cannot be ignored.

Brick and block mortar repair The brick and cement block foundation is strengthened by the mortar that is poured between them. Be careful when you can remove the old mortar with a pencil and hammer. Be careful that the blows you make are gentle to prevent the area from cracking. Apply a little water to the places in the bricks so that the new mortar sticks faster and dries very quickly and prevents new cracks. With a small flat trowel, fill the joints and draw on the mortar until it is smooth and there are no air bubbles. Community Verified icon Silica refractory bricks are a type of refractory bricks that are widely used in the steel industry. Silica refractory bricks have different prices in each city and province. To buy all kinds of silica bricks in each region, you must have up-to-date information about the price of each of them, because bricks, like any other product, have the possibility of changing prices every day. For information on the most up-to-date price of silica refractory bricks, you can refer to reputable dealers and sites selling silica bricks. 
silica bricks specification
Silica brick is one of the types of refractory bricks. This brick can withstand up to 1700 degrees Celsius and can be used in coke, steel and glass furnaces. Refractory bricks are made in different types and each of them can withstand the temperature. Due to their high resistance to heat, firebricks are used in fireplaces, inner linings of industrial furnaces, etc. The general material of refractory bricks or refractory bricks is made of refractory clay, which is a type of porcelain or high quality ceramic. The firing temperature of refractory bricks is around 1500 degrees Celsius. The basis of the materials used in making such bricks are very special minerals and refractory mineral pumice, and refractory materials have high resistance to maintain physical and chemical characteristics. Silica brick is one of the most common types of acid refractories, the main raw material of which is quartzite or refractory silica stones, which were widely used in various industries in the past, especially the steel industry. Due to their high refractoriness, silicon refractories are compatible with high temperature working environments and have high mechanical strength and rigidity up to temperatures almost close to their melting point. They also have the ability to resist dust, soot and acid slag. 
Silica bricks have a thermal expansion of 12 to 15 mm/m at temperatures of 800 to 1000 degrees Celsius, but they exhibit negative expansion at temperatures higher than their limits. At temperatures below 500 degrees Celsius, these bricks have very low resistance to thermal shock, but at temperatures above 600 or 700 degrees, their resistance to thermal shock increases and they show good and acceptable shock resistance. . Therefore, the heating of furnaces covered with silicon bricks should be done slowly and carefully. The density of silica brick is 2.2 to 2.35 grams per cubic centimeter. Silicon oxide is an acidic oxide. Therefore, the chemical resistance of silica brick against acid melts is very good. But vapors and gases containing alkaline compounds cause corrosion of these bricks. This category of refractory bricks is very popular and has a special place in construction and industrial works. In the past, silica facing refractory bricks were used to cover the inner walls of steel production furnaces. Due to its heat conductivity and impermeability to gases, silica bricks are used to cover the inner walls of glass paste production furnaces in glass factories, gas-fired coking furnaces and ceramic production furnaces, hot air blowing devices and roofs of electric furnaces. They have a special use. In addition to the advantages that this brick has, it also has some weaknesses, which are very insignificant compared to the advantages of brick. Among these weaknesses is their low thermal shock resistance, which show low shock resistance at temperatures below 500 degrees. Another disadvantage of this brick is weakness in alkaline environments and in contact (adjacent) with game slags. 
By using firebrick in the facade of the building, you can be sure that the facade of your building will be attractive for future generations and your children as well as the first day. It goes without saying that this is possible if you use standard refractory bricks. There are various types of facing bricks called refractory bricks available in the market, but they do not have the necessary quality in the long term and after a few years of installation, they change color and shape, get algae or dandruff.
