Sandstone blocks for construction and masonry: large blocks
Construction with natural stones is becoming more and more popular. Sandstone blocks is leading the way among them. Large blocks are used to erect buildings and masonry.
Features of the use of large sandstone blocks
The increased density and strength makes it possible to use large stones for foundation construction. Fragments from 40 to 70 cm in length are chosen for this purpose. When masonry works, the same technology is used as for other wall blocks.
The main thing is correct preparation of the mortar. For this purpose, a special tile adhesive is added to the mixture of sand and cement. In terms of volume, the amount of adhesive should be equal to sand. Not diluted glue is undesirable, as it will make the structure airtight.
Advantages and disadvantages of large sandstone blocks
Advantages of the mineral in construction:
- decorative effect;
- durability and resistance to negative environmental factors (precipitation, wind, extreme temperatures);
- easily processed (sawing, grinding) and has a non-slippery surface;
- resistant to abrasion and wear, no maintenance required;
- reasonable price.
The building material has one drawback: high specific weight (2300-2600 kg per m. cube).
