Ytong Blocchi forged blocks are used for the rapid creation of vertical stiffeners in masonry.‎ The block-formwork has a vertical hole in which the metal reinforcements can be placed and then the concrete cast.‎ The perforatedblocks are 25 cm high for 20 cm thickness and 20 cm high for 24-30-36-40 cm thickness, with a length of 62.‎5 cm.‎ The circular section of the perforated block has a diameter of 12.‎5 cm for 20 cm thickness, a diameter of 15 cm for 24 cm thickness, and a diameter of 20 cm for 30-36-40 cm thickness.‎ Before laying the perforated blocks, provide reinforcing irons or chemically grouted irons in the underlying reinforced concrete curb, which must be connected to the reinforcement cage of the pillar.‎ After laying the reinforcing irons, proceed with the overlapping of the perforated blocks and in the formwork thus obtained, insert reinforcement and concrete according to the indications of the designer calculating the work in accordance with the regulations in force.‎ More than 100 years ago, in 1923, architect and researcher Dr.‎ Axel Eriksson invented "vapor-vulcanized gas concrete" in Sweden - now known as autoclaved aerated concrete.‎ Together with Carl August Carlén, an entrepreneur, they started the first production in 1929 in Yxhult, southern Sweden, at a time of great scarcity of raw materials and stricter energy laws.‎ A competitive advantage on the market The sustainability of buildings is increasingly at the center of construction trends, with modern sustainability policies undertaken by international institutions and organizations that have favored the increase of this trend.‎ The choice of materials and construction technologies are fundamental to obtaining homes that consume less and consequently have a lower environmental impact.‎ A sustainable home can cost on average 8% more than a normal home, but this difference is compensated by numerous advantages in the long term: a healthier and more comfortable environment, significant economic savings compared to bills and a higher value of the building; It is estimated, in fact, that the value of a green property can increase from 2 to 10% with sales times halved from 8 to 4 months.‎
