- Q; What are the harmful materials in aggregates? What are their harmful effects? Subject: Concrete Technology Department: BE-Civil EngineeringA contractor claims that the mean compressive strength for a concrete mix is 32.4 MPa and that it has a standard deviation of 2.8 MPa. If you break 16 cylinders and obtain a mean compressive strength of 30.3 MPa, would you believe the contractor’s claim? Why? (Hint: Use statistical t-test.)Estimate the tensile strength required to prevent cracking in a concrete-like material that is cast into a bar, 50 in. long, and is fully restrained at each end against axial movement. The concrete is initially cast and cured at a temperature of 100°F and subsequently cools to a temperature of 0°F. Assumethat the modulus of elasticity is 5 million psi and the thermal coefficient is 5 * 10-6 in./in./°F.
