Regarding final exam

Dear all

Please find below the suggestions from course instructors regarding the final exams.

The exam will be online. The students are expected to study both lecture notes and other reference or textbook materials. The students can expect multiple choice questions similar to what was discussed in the special lectures and assignments. However, expecting the same pattern all throughout the paper may not be appropriate. Similarly, the level of difficulty could vary for each question and hence, a thorough study and understanding of the subject from the student is warranted so that he/she should be capable of handling the exam wisely.

All the best for your exam.

Regarding Statement B of Question 1 of assignment 2

Dear all

Statement B of Question 1 of assignment 2 states "  Aggregate samples are subjected to little or no impact loads in Deval’s abrasion test"

This statement is True.

Explanation: the subject on aggregate, cement and concrete is not rocket science and very much relative (i.e., nothing is absolutely true, everything is true when comparing one with another and viceversa). It is carefully mentioned in the lecture that there is no impact of aggregates in Devals abrasion test primarily because this is explained in comparison with Los Angeles absrasion test. In question, it is carefully stated that "Aggregate samples are subjected to little or no impact loads in Deval’s abrasion test" and this question is generally on "Abrasion test." In addition, both "little or no impact loads" is given in the question clearly and the answer for the line is "True." 

In case if any other explanation is given earlier kindly ignore it.
