Which of the below property of aggregates is not desirable?

Which of the below property of aggregates is not desirable? Correct Answer Angular shape

Aggregates should provide space for cement paste so as to lubricate the area. The parameters like texture, size, shape, grading are to be considered. Larger size, cubical, round and rough textured aggregates are preferred.

Read the passage and answer the questions that follow. Evaluation of candidate vaccines for COVID-19 should be done on technical parameters and programmatic suitability. An ideal vaccine would provide the following- immunity that is of a high degree (90%+ protective especially against severe illness), broad-scale (against different variants) and durable (at least five years if not lifelong); a vaccine that is safe (little or no side effects and definitely no serious adverse effects); a vaccine that is cheap (similar to current childhood vaccines); a vaccine that is programmatically suitable- single dose, can be kept at room temperature or at worst needs simple refrigeration between 2 degrees Celsius and 4 degrees Celsius, needle-free delivery, and a vaccine that is available is multi-dose vials, has long shelf life and is amenable to rapid production. Obviously, a vaccine having all these desirable characteristics is a pipe dream, and most vaccines fare well in some and not so well in other parameters, making it difficult to choose between them. According to the passage, which of the following is NOT a desirable parameter for a vaccine?
Which of the following statements are correct with reference to ensuring minimum shrinkage of prestressed concrete? 1. The water-cement ratio and proportion of cement paste should be kept minimum to reduce shrinkage. 2. Aggregates of larger size, well graded for minimum void, need a smaller amount of cement paste, and attendant shrinkage will be smaller. 3. Harder and denser aggregates of low water absorptions and high modulus of elasticity will exhibit small shrinkage.
