Fly ash bricks are constructed from industrial waste materials like fly ash, a by-product of coal-fired power plants. It is mixed with water, cement, and other materials to create a paste. Then, a fly ash brick making machine is used to pour the paste into molds and bake them at high temperatures to manufacture lightweight, durable bricks. Properties: Primary properties of fly ash bricks include impressive compressive strength, high melting point, non-toxic nature, excellent sound insulation, high durability, and eco-friendliness. ------------------------- What are Red Bricks? Red bricks, also known as clay bricks, are the building materials made of natural clay. They have been used in the construction business for centuries worldwide. However, they have some environmental issues because they create pollution, are against world food security standards, and cause the cutting of hills and agricultural land. Moreover, they have a heavier weight and non-uniform shape, making them more labour-intensive to transport and install. ----------------------- Which is Easier to Install? Fly Ash Bricks or Red Bricks Fly ash bricks are larger and lighter in size, making them easier to ship and install. It results in a faster installation process compared to red bricks. Comparatively, red bricks require more attention and skill to achieve a uniform and clean installation. Moreover, fly ash bricks require fewer materials for installation, which only includes laying a thin layer of cement mortar. On the contrary, red bricks need a thicker layer of sand-cement mortar due to their more absorbent and porous structure, causing them to crumble if they do not get the proper support.
