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?

Two batches of concrete cylinders were made with and without a calciumchloride (CaCl2) accelerator admixture. Six cylinders were made of each batch andsubmerged in water for different times before testing for compressive strengthand the results are shown in Table P6.35.It is required to do the following:a. Using an Excel sheet, plot the relationship between curing time andcompressive strength of the two mixes on the same graph. Label all axesand curves.b. Comment on the effect of the accelerator on the compressive strength ofPCC at early and late ages.
