Portland Cement Concrete - an overview

Portland cement concrete, in particular high strength concrete, is highly susceptible to spalling in a fire [37]. High strength concretes are generally defined as concretes with compressive strengths above 50 MPa, and are widely used in construction since the late 1980s. spalling of high strength concrete, first reported in 1993 [ 37 ], is an explosive dislodgement of pieces from the surface of concrete in a fire.
