Read the given statement and conclusions and select the correct option. Statement: In the design of a concrete mix, the proportion of coarse aggregate to fine aggregate affects the workability and strength of the concrete. It is often recommended to use a well-graded aggregate to improve the mix's properties. Conclusion 1: Using a well-graded aggregate generally improves the workability and reduces the voids in the concrete mix. Conclusion 2: A higher proportion of coarse aggregate relative to fine aggregate will always increase the compressive strength of the concrete.
- 1Only Conclusion 2 is correct.
- 2Neither Conclusion 1 nor Conclusion 2 is correct.
- 3Only Conclusion 1 is correct.✓
- 4Both Conclusion 1 and Conclusion 2 are correct.
