Discussion: 1- What is the difference between apparent specific weight and total specific weight? 2- If an error occurred and the model dried more than the case of S.S.D saturated and the surface is dry), what is the effect of this on the total specific weight and the apparent specific weight. 3- What are the difficulties that arise when using aggregates containing free water or dry aggregates in concrete mixtures? How to overcome this: A - in the laboratory? b- On the job site?
