Smart Concrete

Smart concrete has made from carbon fibre reinforced concrete. It has a very high compressive strength. This concrete has a sense of strain or stress. By using admixture it becomes sensor. This sensing ability is due to the change of electrical resistance.

Types of Smart Concrete

Ø Transparent Concrete

Ø High Volume Fly Ash Concrete

Ø Silica Fumes Concrete

Ø Self Healing Concrete

Ø Light Weight Concrete

Ø Polymer Concrete

Ø Self Compacting Concrete

Ø Bacterial concrete

Ø Fibre-reinforced concrete

Ø Pervious concrete

Ø Water-proof concrete

Ø Temperature controlled concrete

Ø Coloured concrete

It is widely used to construct civil engineering marvellous building, highway, bridges, runways for airport, continuous slab-type sleepers for high-speed trains, dams, and nuclear power plants, and especially has great potential in the field of structural health monitoring, traffic.

It contain short carbon fibres, typically 5 mm in length, Fibre content is 0.2 vol. % of cement, Silica fume content is 15% by weight of cement, Methylcellulose content is 0.4% by weight of cement.

Main drawback of this concrete is that it is quite costly than normal concrete so becomes uneconomical. It is not suitable for Indian atmospheric condition. It gives better results only if comes in contact with water.
