TRADITIONAL BRICK IS MORE VULNERABLE IN EARTHQUAKE

Dr. Ahmad Kamruzzaman Majumder

The history of brick making is not known to me but nearly 2050 years ago temple were made of these traditional brick. Nowadays the style of making home is that the cement and sand is kept between two brick but previously it’s a clay that is kept between two brick. In ancient times the styles of roof were also different. It used to be flat tiles but nowadays concrete and steel are used for making the roof. In ancient times the tiles were also made up of clay mud after burning in the fire. Today in Bangladesh the size of brick is 9.5''X4.5''X2.75'' which is seen all over the country. This brick is kept one after another and make the wall. In between two brick the paste of cement and sand is being used as a binding material. The readers might think that all these things are earlier whenever we keep our eyes it is seen. What new to tell. My opinion is that year after year we are doing the same mistake to make our buildings in local construction practice by using those ancient clay brick. What is this mistake and to recover the mistake and doing appropriate work is not concerned by anyone. When I saw that one or two organization understood this problem and try to change the ancient brick use and to do something new and facing lots of criticism then there is no other way except being disappointed. honestly speaking when the use of clay brick started is not known to me but in some places some temples are found to be mad by brick as per I know except Bangladesh west Bengal and Tripura of India and Nepal are not using this type of clay brick. No doubt Bangladesh is an earthquake prone county if we consider environmental, over weight/ heavy weight and earthquake we should not use. Clay mud made these traditional brick following are the some reason why people are using year after year this
