Make a new building with smart bricks - স্মার্ট ইট দিয়ে একটি নতুন বিল্ড...

SubhanAllah !! Watch the video once! Looking at the horizon in the dry season that means going to Ashulia or Savar in November-April, you will feel that the clouds are clouded in the sky and the rain is coming to mean. But if you give a little more attention, you can understand that it is not. In fact, the black smoke of brick burning in the brick fields has covered the sky. This is not the end here.

Apart from environmental pollution, brick fields also waste cropland, ground soil, groundwater and fuel. Studies have shown that the number of cultivated land is reduced by 42,000 hectares per annum, due to the establishment of brick and using ground-surface soil. Another study shows that the amount of organic matter in the area around the brick field is only 1, 64 percent, The amount of land is 2.45 percent.

According to experts, for natural regeneration, groundwater used in the brick field can take up to 20 years in place.

Bricks are one of our main building materials because there is not enough wood, stone, and iron in the country. Although reliable information-data is not available in this sector, it is assumed that 1 percent of the country's total production comes from the national importance of this sector. As well as employment of about two million workers, a large part of which is women. There are about 1,700 million bricks and bricks produced from around 10 thousand brickbats annually. Brick demand is increasing due to the increase in development-related construction and the trend of construction of tin or tin in the rural areas instead of tin or raw house.

Recently, considering the adverse impact of the brickwork on the environment, and the technical excellence has been achieved in the interest of preservation and development of environment and biodiversity. Bricks are now mainly produced in two ways: (1) burned down (2) not burnt. Apart from this, it is possible to prepare hollow bricks using less raw materials in both ways. In the burnt brick, the bricks are made by bundling of sand, cement, fly ash, gypsum etc. with the help of a foaming agent. Not the main advantages of burnt bricks are that the soil is not used in this field, pollutants, coal or any other fuel is not burnt and the use of water is much less than brick bricks.
