RESULTS FOR MATERIALS IN CONCRETE. The principal ingredients that make up the concrete mix are: cement, fine aggregate, coarse aggregate, water, chemical admixtures, and mineral admixtures. Concrete used in construction may also contain reinforcing bars, welded wire fabric (wire mesh), and various reinforcing fibers.
Concrete is a construction material composed of cement, fine aggregates (sand) and coarse aggregates mixed with water which hardens with time. Portland cement is the commonly used type of cement for production of concrete. Concrete technology deals with study of properties of concrete and its practical applications.
- Lime Concrete. Lime concrete uses Lime as the binding material. Lime is usually mixed with surki and khoa or stones in the proportion 1:2:5 unless otherwise specified.
- Cement Concrete. Most engineering construction uses cement concrete composites as the main building material. It consists of cement, sand, brick chips, or stone chips of the required size.
- Reinforced Cement Concretes. For enhancing the tensile strength of concrete, steel reinforcements are added. Sometimes, RCC is prestressed under compression to eliminate or reduce tensile stresses.
- Dry Ready Mix Concrete. This is the combination that may be found at most home improvement and hardware stores. It comes in baggage typically starting from sixty to eighty pounds.
Apr 3, 2020 · Though many use "cement" and "concrete" interchangeably, they actually refer to two different — but related — materials: Concrete is a composite made from several materials, one of which is cement. Cement production begins with limestone, a sedimentary rock.
