Concrete Mix Ratios - Cement, Sand, Aggregate and Water
The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

Portland Cement Concrete - an overview - ScienceDirect
15.5.2 Fire test results. 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
