Arun! i better dont say the construction technique coz i preferably speak about the material i.e BAMBOO which has an pretty good tendency to replace concrete in few design scenarios. We have for example bamboo houses,Bridges many structures made out of it.

Coming to Techniques, that would be Recycling, Reducing the material used for constructions!!!

You may use bio degradable chemical aditives for concrete curing, we can get non-harmful products nowadays, for example at BASF brand.

The first is reusing construction demolition waste as recycled aggregate to form an environmental- friendly concrete. The second is using industrial wastes (Fly ash, Blast furnace slag, glass, silica dust, steel slag, etc.) as replacement materials to both cement and aggregate for concrete. These more sustainable concrete are expected to play a key role in construction of safer mega cities in the coming time as it can help to cut down large volume of carbon dioxide emitted from cement production and also reduce pollution from exploitation of natural raw materials.

concrete building solutions for green credits through a level of cement reduction by using supplementary cementitious materials (SCMs) such as fly ash or blast furnace slag. Portland cement is not considered as an environmentally friendly material, because its manufacture creates greenhouse gas emissions.
