Concrete is weak in tension becauseof the presence of a weak link within the concrete matrix known as the Interfacial Transition Zone of ITZ. Concrete is mainly composed of rock aggregates that are glued together by a cement paste which is a mixture of cement and water. ...
(41.4N/mm2)can be ot\btained.But concrete is very weak in tension,and so has to be adequately reinforced with steel bars .The concrete then takes the compression,and the steel takes all the tension.Both materials work together as a composite material.This material is then called reinforced ...
