What does the Sand Cone Method measure?
Think about the purpose of the method.
What type of apparatus is used in the Sand Cone Method?
Consider what key tool is involved in the method.
What does the Sand Cone Method primarily measure?
Focus on what aspect of the soil the method looks at.
True or False: The Sand Cone Method does not compare field results to laboratory results.
Think about the purpose of the method.
Field measurements show that the in-situ dry density is 550 kg/m³, while the lab-determined MDD is at 600 kg/m³. Is the field density acceptable, and what actions would you recommend?
Consider the percentages involved to guide your analysis.
The weight of the soil removed from an excavated hole is 8 kg, and it took 0.04 m³ of sand to fill the void. Calculate the in-situ dry density and assess if it meets an MDD of 700 kg/m³.
Use the density formula you learned earlier.
