Coarse aggregate and total water intuition
WebQ. How can the surface or free water carried by the aggregates be determined? A. Free water is simply the difference between the mass of a sample of wet-saturated aggregate and the mass of the same sample in the saturated-surface-dry condition. Standard test methods for surface moisture in fine aggregate are available (ASTM C70). WebA batch of concrete consisted of 200 lbs fine aggregate (sand), 400 lbs coarse aggregate (gravel), 95 lbs cement, and 5 gallons of water. The relative density of the sand and gravel may be taken as 0.65 and that the cement as 3.10 What was …

WebOverview. The coarse aggregate specific gravity test (Figure 1) is used to calculate the specific gravity of a coarse aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is similar in nature to the fine aggregate specific gravity test.

WebApr 27, 2012 · Correcting for Water in Aggregate . Concrete is made of three main materials: aggregate, cement, and water. In automated production environments, these are normally measured by weight. As the aggregates are stored outside and subject to environmental conditions, their moisture can vary, for example, with sand, between 1 …
