plant fibres as aggregates in concrete
Reinforced Concrete Used in Civil Construction
Reinforced concrete is used in the structures of buildings and it is differentiated from normal concrete because it has a metallic frame for resisting tractive effects, whereas the concrete itself resists the compression. It is composed of a compact mixture of medium aggregates such as broken rocks and rolled pebbles, small aggregates like sand and pebbles, water, and additives.
