Garden 'standing' on the wall thanks to bio-concrete

Thanks to a bio-concrete, dream of planting trees on the wall, the roof of many will become a reality.

Antonio Aguado, a scientist at the Catanulya Polytechnic Institute in Spain, and his colleagues have found a way to make bio-concrete to meet the vertical needs of Mediterranean people in the Mediterranean. In recent years, Gizmag reported.

Bio-concrete still contains magnesium phosphate as traditional concrete to create a favorable environment for the growth of microalgae, fungi, lichens and moss in Mediterranean climates. However, the proportion of components in the biological concrete is adjusted to increase the porosity and reduce the hardness of the concrete surface so that the plant can grow.

In structure, Aguado's biological concrete consists of three layers. By touching the surface of the building, the bottom layer will be waterproof. Water retention layer in the middle and upper suction layer. The team asserts that users can plant trees on their concrete after about a year - the time it takes for moss and other microorganisms to grow. But after that time, they will not need regular maintenance.

The research team found that if the plants grow on concrete, they will become soundproofed, heat-insulating. In addition, if all homes are standing gardens, they will create beautiful landscapes and contribute to reducing greenhouse gas emissions.
