Mass Concrete - Portland Cement Association

Mass concrete is defined by the American Concrete Institute as: “any volume of concrete in which a combination of dimensions of the member being cast, the boundary conditions, the characteristics of the concrete mixture, and the ambient conditions can lead to undesirable thermal stresses, cracking, deleterious chemical reactions, or reduction in the long-term strength as a result of elevated ...

Mass Concrete - What is Mass Concrete Where It Is Used

Nov 22, 2017  The concrete placed in different massive structures such as dams, bridge piers, canal locks, etc is known as mass concrete. In mass concrete, larger size aggregates (up to 150 mm maximum) and low slump (very stiff consistency) are used to reduce the amount of cement in the concrete mix (normally 5 bags per m3 of mass concrete).

Mass concrete - Wikipedia

Mass concrete is defined by American Concrete Institute Committee 207 as "any volume of concrete with dimensions large enough to require that measures be taken to cope with the generation of heat from hydration of cement and attendant volume change to minimize cracking." As interior temperature of mass concrete rises due to the process of cementhydration, the outer concrete may be cooling and contracting. If the temperature differs too much within the structure, the material ca

EARLY HISTORY OF MASS CONCRETE

Dr. Roy W. Carlson was a giant in the field of mass concrete for large concrete dams. His pioneering work on stress meters, low-heat cements, and mathematical models for concrete had a tremendous influence in the field. Here he recollects his first works in the field. Not much was known about internal heating of concrete before 1925. In that year
