1:8:16 with ballast 20mm nominal size.
Also, since concrete is specified on the basis of strength in practice and the use of cement combinations could result in better performance at equal strength than at equal water/cement ratio [28,29], it becomes expedient to investigate the absorption characteristics of the concretes at equal strengths in order to provide more information on their durability and therefore suitability as alternatives to Portland cement concrete
Civil engineers who specialize in concrete and composites present 50 papers on such topics as using heat pretreatment to reduce the explosive spalling of high performance concrete, mechanical properties and resistance to water ingress of cement concrete
made with non-cyclic alkanes, a comparative investigation of some properties related to the durability of cement concretes
containing different fly ashes, mechanical and thermal properties of moderate-strength concrete with ceramic powder used as supplementary cementitious material, and mechanical and thermal properties of composites containing waste coir pith.
Briefly speaking, the rubberized concrete is a structure of conventional cement concrete
comprising crumb rubber.
Permissible uses for RCA in Michigan include as aggregate within Portland cement concrete

Over that time period, portland cement concrete
has become one of the most important of our construction materials for roads, buildings, and other large
Transportation Department's Federal Highway Administration (FHWA) has developed a method to determine the precise rate at which portland cement concrete
(PCC) contracts and expands during temperature changes.

A tremendous quantity of infrastructure Portland Cement Concrete
(PCC) is nearing the end of its useful life in the United States, and much of this concrete has the potential to be used as recycled concrete aggregate (RCA).
