compressive strength of burnt clay bricks

Categories: Μη κατηγοριοποιημένο

If the sound is dull ringing sound that the brick is said to be sound and hard but if it gives dull thud sound it is said to be soft useless brick. Among properties of bricks, there are some basic ones which are related to the physical character and there are some additional properties that describe their mechanical properties, durability and thermal characteristics. The compressive strength property of brick depends on the composition of clay and the degree of burning. 6:06. 5.2 Hand-moulded bricks of 90 mm or 70 111111 height shall be moulded with a frog 10 to 20 mrn How to Build a Traditional Barn Roof - … Mohan A Recommended for you. WATER ABSORPTION Saad Iqbal is a civil engineering geek and a passionate blogger from Pakistan – with handy graphics designing skills. Place the specimen prepared with flat faces horizontal and mortar filled faces (i.e., frog face) upwards between two 3mm plywood sheets and carefully centred between plates of testing machine. Procedure of Compressive Strength Test on Bricks. This is very important property of brick because the longevity and durable life of brick is directly related with its hardness. This phenomenon is termed as efflorescence. 1. • Its resilient and sustainable characteristics against forces of nature are not new or not unknown. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces. Your email address will not be published. It has the ability to absorb heat at fast rate but would release it at very slow rate and in doing so it can save up to 30 % energy making it a useful material for energy efficient buildings. When the bricks have a proper structure they can offer protection against fire with maximum rating of 6 hours. Introduction It is universally acknowledged that shelter is the basic need for both psychological and physical comfort of mankind (Saridharan and Venkatappa, 1973). Compressive strength of the brick is calculated in the following way. But as it is made with a clay, it has hundreds of voids in it that joins up to form capillaries for water to get absorbed. The specimen should be then removed and excess water is drained out at room temperature. determination of compressive strength of burnt clay building bricks. The 15 % replacement of sludge with RSA, SBA and WSA waste resulted in approximately 9.82 %, 11.04 % and 11.66 % lighter bricks compared with control bricks. Test for compressive strength. brick of classification 100 is further sub-classified as 100A and 100B and so on. Compressive /Crushing Strength of Bricks Compressive /Crushing strength of bricks (Indian Made) are very variable, and may vary from 30 kg/sq. codes that an ordinary type building brick must possess a minimum compressive strength of 35 kg/cm 2 . Generally, plenteous useful properties of bricks exist making it the widest used and most popular construction material. The frog portion and voids on the top surface if any has to be filled with cement mortar (1 cement,1 clean coarse sand of grade 3mm and down). Creative Head : A. Mohan K. Venkat Raman Project Assistant : A.John Kennedy S. Rajkumar Technical Support: P. Sadhan V. Vignesh Kumar Although the production of this flowery white powder is apparently not detrimental to the structural integrity of the brick wall. The plywood sheets will ensure that the load is transferred uniformly. The difference of these weights are noted as percentage to give %age absorption of bricks. Remove any unevenness observed on the bed faces (i.e., frog side and on the opposite side) by grinding. Pune, Maharashtra 411014. The load determined as a result required for crushing is divided by surface area of the brick to get the required value of compressive strength in units of N/mm2. After 24 hours, these saturated bricks are weight to get saturate / wet weight. Bricks are generally hard because of baking in kiln and if you scratch the brick with nails it must not produce any impression. If properly managed, this property is very useful in terms of regulating the temperature and humidity inside temperature. • RSA, SBA and WSA changed the bulk density of the clay bricks, making them lighter. So I have tried to explain various properties of bricks, please don’t forget to share it with your friends on social networking sites. So bricks do have water absorption properties that are sometimes in such a large quantity that the water could percolate towards the inside face of the wall, no matter how much thickness is of the wall. Five (5) number of burnt clay bricks are to be tested and the average compressive strength value has to be reported. The conductivity of heat and sound through bricks is dependent on density and porosity of bricks. Center Line Method for Calculating the Quantities of Building Materials. cm, and even … As per ‘National Building Code of India’ (1983), the compressive strength of brick should be of minimum 3.5 N/mm 2 i.e. These pores make up capillaries for the water to get absorbed. The compressive strength property of brick depends on the composition of clay and the degree of burning. Save my name, email, and website in this browser for the next time I comment.
