    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

    Mar 01, 2021· Concrete pavement is continuously subjected to traffic and, in some cases, severe climatic conditions. Because of its relatively high stiffness, concrete pavements spread the imposed loads over large areas of the subgrade and are capable of resisting deformation caused by passing vehicles. The major variables likely to affect the performance of a well-designed concrete pavement
