Description : Is it desirable to use concrete of very high strength i.e. exceeding 60MPa? What are the potential problems associated with such high strength concrete?
Last Answer : To increase the strength of concrete, say from 40MPa to 80MPa, it definitely helps in improving the structural performance of the structure by producing a denser, more durable and higher load ... Moreover, owing to a low aggregate content of high strength concrete, creep and shrinkage increases.
