Of course, most (2, 3 times) cross-sectional area is better for the stability of a brick pillar height of 2.3 m. But that's the hitch and all – if the area is increased by 2.3 times, and consumption materials also increased by 2.3 times. Not raise eyebrows with surprise – is not fit digits (height and volume increase) with the same brush and coincidence. So, if in the first case (25 X 25 cm) the volume of masonry pillars will be 1.75 m3, to which required 710 units. 0.45 m3 of brick and mortar M-100, or 140 kg of cement M-400, the second (38 X 38 cm) volume has already reached 4,0 m3, and therefore require a brick 1650 pcs. and cement M-100 – 1.0 m3, or 300 kg of cement M-400.
So imagine that you are profitable? 710 or 1650 pcs. Brick, 140 or 300 kg of cement? There is a difference, right? I will be in this case to focus on cross-section columns specified in the drawings, that is 25 X 25 cm must say that the laying of brick pillars, the more such small cross-section and a height refers to vysokorazryadnoy masonry. I am not saying this to scare you and add yourself to discourage these posts, but quite the contrary, that others are not scared and repulsed this hunt. In the end, not the gods of the same pots burn. And then, I – you. And so, modestly speaking, 70% success guarantee, plus your 30 / o – 15 / 15 and the courage / audacity to. And everything will be all right. Go to your existing instrument bricklayer make a new rule length of 1.5 – 1.75 m instead of meter.
