EFFICIENT MATERIALS FOR STRONGER STRUCTURES

Briquettes are compact bricks of saw dust, fodder, dried leaves, agricultural waste, cow dung (binder), sugarcane molasses (self-binding) etc. that may be used as fuel in the chulhas or boilers. These are generally kept cylindrical to increase the overall burning efficiency of the briquettes. The compact nature increases the calorific value of the fuel. When the briquettes are made, the dried leaves/sawdust is mixed with a binder like cow dung in an appropriate proportion. This mixture is subjected to high pressure for some period and finally briquettes are obtained.
One can come up with an affordable and efficient solution for automation of this whole procedure (mixing and pressing) of briquette making, or suggest a better method for briquette making
Efficient Materials for stronger structures :-Houses in the rural areas are built of different materials – mud, straws, wood, bricks etc. Could the binding be done stronger with other commonplace materials, or could the materials themselves be replaced with something more inherently stronger? Apply basic concepts to change the way these dainty houses are built.
Suggest some such methods for using more efficient building materials for building a residential structure and also describe the use of such materials in the construction giving proper financial and technical details.
