Utilizing Rammed earth , Mine Tailings , Agriculture waste as Substitute Construction Material sector.
Building Sustainable affordable Modern Homes in Zimbabwe.
Rammed Earth
Rammed Earth or compress earth is the oldest techniques used in construction, the Great Wall of China, the castles in Spain , turkeys, Yemen and Timbuktu are built using same techniques.
Rammed Earth is the selection of native materials available in abundance, which after serving can be pilled in layer, forming a sort of geological deposition. Rammed Earth materials are mainly soils , fly-ashes , clay.
Rammed earth texture varies depending on the soil pigmentation, we can used additives to malaxe the colouring. To obtain a very durable rammed earth, Ranuko housing solutions develop our eco friendly reinforcement meshed. With our innovative of integrating reinforced meshes the wall of ( 2 metres height and 3 meters long , 0.3 m thickness ) can withstand a 500kg - 750 kg overburden weight. Compressed earth wall which integrates reinforced meshes can withstand lateral forces such as tornadoes, rain, storms, and torrential winds.
Mining Tailings
Mine Tailings or mining waste have been used in previous studies by Ranuko housing solutions as substitute construction material to recycle waste products, especially in hollow blocks and bricks production and as masonry mortar. The study investigated the use of pollymetaic copper and bauxite mine tailings in provenance from Republic Democratic of Congo and Guinée Conakry , a mining waste material consisting of finely grinded siliceous particles and other pollymetalic were obtained from Tailings Pond of mining company in Nkankan Guinée Conakry and Lubumbashi (DR Congo ).
A comprehensive experimental program was conducted to investigate the comparative compressive strength of Fly-ash containing Porac sand versus copper or bauxite mine Tailings , and the durability of the mine Tailings and fly-ash were put into test. Varying mixtures or ratio of Mining tailing , sand , fly ashes , and group 2 synthesis biding agent were test in contrast to Portland cement with zero or non-existing cement content , a low, medium, and high cement contents were casted and tested. The results obtained came back that the mining tailings/waste was 7% stronger than concrete.
Agriculture Waste
Most of agriculture waste incorporated in agriculture as coal-ashes or biogas, in Ranuko housing industry, we are experimented building house using agriculture waste with mycelium substances which is a fungi base organisms.
The results obtained is very promising, as the mycelium blocks are fire-resistance, can replace wooden beams and mitigate deforestation, provide stunning materials for interior design in construction, .
Other materials we are experiencing are hempcrete , which has a considerable compressive strength similar to Portland cement and greater than aircrete .
