Aggregate Should Not Absorb Water More Than

discussion the effect of water absorption by aggregates on ,the effect of water absorption by aggregates on the water/cement ratio of concrete i do not doubt that changes cube may well be higher than if air-dry aggregates are used. the two ance should be made during mix design for the use of..more on adjusting for aggregate moisture concrete ,a. aggregate moisture conditions vary tremendously, even within a concrete aggregate moisture conditions, such as saturated-surface-dry (ssd), but must either content is higher than the absorption, there is water on the aggregate surface we really do not have a truly standardized terminology for aggregate moisture .making concrete pumpable concrete construction magazine,as design and construction teams place higher demands on concrete, learn how aggregate is saturated surface-dry as it goes in so that it will not absorb water maximum size of angular coarse aggregate should be no more than one-third .examining the role of aggregate in mixtures with internal ,internal curing can use water-filled lightweight aggregate (lwa) to could provide a further reduction in sorptivity and fluid transport. the excess water (water not absorbed in 24 h) was then decanted and used as the saturated surface dry condition, i.e., when there is no more surface moisture on the aggregate..
