Study of the effects of cogrinding of sand and clinker on the properties of sandcrete

摘要

Mineral additions can be mixed with the clinker before the grinding process. Thus, one obtains a 'coground' binder which can allow some reduction in the cement ratio. Some dune sand is added, in variable proportions , to the clinker, such as to obtain a coground binder from which different sandcrete mixes are defined. To distinguish the effects of the binder fineness from those of the addition ratio, a two-stage experimental design process has been followed. In a first stage, the fineness of the coground binder has been quantified.
