The main function of the mortar joint of the masonry is to bond adjacent bricks and evenly transmit pressure, so that the wall is evenly stressed, the firmness is improved, and the integrity of the wall is improved. Construction specifications have strict requirements on the size of the mortar joint, the smaller mortar joint can influence the bonding degree between adjacent bricks, and on the contrary, the larger mortar joint can influence the accuracy and the pressure resistance of the wall size due to the dry shrinkage of mortar filling the mortar joint. The gap between the brick bodies 1 of two liang of contacts is very little when building by laying bricks or stones for the hollow brick of this design to the influence of mortar joint to brickwork wholeness and fastness has been avoided. According to the requirements, the diameter of the through hole 10 is 12mm, the diameter of the masonry mortar groove is 20mm, and the hollow brick has no plastering groove, basically has no mortar joint, is flat and compact in combination of adjacent bricks, and can be used as natural decoration of a wall surface.
Calculate the porosity of the individual hollow blocks:
p = hole volume/profile volume of shaped brick
=（240×10×115+80×π×102×2+1/2×240×102π+80×20×30+80×50×π×62）/（240×115×90）×100%
=(276000+50240+37680+48000+452160)/240×115×90=864080/2484000×100%
=34.786%。
It can be seen that the porosity of the hollow block is closer to about 35% of the porosity of the hollow block, and is therefore defined as a hollow block.
