Question 10 The following are disadvantage of concrete except O Low fire resistance O Shrinkage and creep O None of the choices. O Forms and shoring 3 pts
Question 9 3 pts If the depth of compression block in the concrete at failure is 130 mm, calculate the maximum possible value of the depth of the neutral axis in mm. O 233.667 O 200 O 152.941 O 173.333 Next
D 3 pts Question 7 Which of the following statements is false about the stress strain diagram of concrete. O The rising portion of the stress-strain curve resembles a parabola with its vertex at the maximum stress. O The slope of the descending branch of the stress- strain curve results from the destruction of the structure of the concrete, caused by the spread of microcracking and overall cracking. O The initial slope of the curves (initial tangent modulus of elasticity) decreases with an increase in compressive strength. O The strain at maximum stress increases as the concrete strength increases. Nout
3 pts Question 6 The following procedures will offer an increase in the compressive strength of concrete except O The use angular aggregates rather than rounded aggregates O Prolonged curing O Reduction in water cement ratio O Rapid loading rate than standard rate is used in the short term compression test. O All of the choices
Question 5 It is the slope of the stress-strain curve at the origin. O Initial tangent modulus of elasticity O Tangent modulus of elasticity O Secant modulus of elasticity Poisson's Ratio of concrete << Previous
