Fired bricks refer to bricks made from clay,shale,coal gangue,and other raw materials,which are formed and high-temperature baked.At present,fired bricks can be used in various occasions,and their specifications and sizes need to be selected according to specific construction scenarios.In terms of specifications,fired bricks not only have different lengths,but also different thicknesses.The application scenarios of fired bricks with different thicknesses are also different,so it is necessary to make corresponding distinctions and distinguish the areas where they should be used.
1.In terms of the thickness of fired bricks,we can consider laying 40mm pedestrian walkways,50mm vehicular and fire lanes,and 60mm heavy-duty lanes based on the required strength and compressive strength.Due to the much higher strength of fired bricks compared to cement bricks,this thickness of fired bricks is still sufficient for the corresponding lane.
2.Fired bricks are sintered in a high temperature environment of 1100℃to 1200℃,so there is almost a natural size error of±2mm.So we should leave a gap of about 2mm between bricks during the paving process,so that the paving effect can be more ideal.
When choosing fired bricks,the thickness selection must be based on the actual situation.If we choose a smaller thickness in areas with high strength requirements,the service life of fired bricks will inevitably be shortened and the cost of use will also increase;If thicker materials are chosen in areas where strength requirements are not high,it will also result in increased costs and resource waste.Choosing the appropriate fired brick will also leverage its thickness advantage,making it more suitable for use.
