Aggregate properties
Do not write the whole report. Just write two parts of it which is the procedure of the six parts of this report and the group discussion.
1. Using your gradation analysis and the stockpile definitions given in ASTM D448, determine the most likely aggregate stockpile that you sieved.
2. List and discuss three potential problems with a sieve analysis. How would each problem affect the test results?
3. In ASTM C128 and ASTM C127, what would be the consequences of failing to dry the aggregate to SSD before weighing it? Use a simple numerical example to prove your conclusion.
4. How is absorption of the aggregate related to the workability of concrete and to the amount of binder that is needed in an AC mix?
5. The method to find the specific gravity of coarse and fine aggregates is different, but both are based on the same basic physical phenomenon. What is this phenomenon? Explain the formulas used to calculate the fine and coarse specific gravities as well as the absorption.
6. Why is it important to calculate the specific gravity for both dry and SSD condition?
Paper format: MLA
Paper details: Do not write the whole report. Just write two parts of it which is the procedure of the six parts of this report and the group discussion. You'll just need to work with the group discussion questions. Search for them in google or from your knowledge if you took this class before. Comments from Support Team: The procedure part is for all the six parts of the report not only for part six. I just want to clear this out for you. Discipline: Civil engineering materials

Calculate the work done and the heat transfer. Hint: Use the ideal gas law pv = RT to nd the temperature at the end of compression. Take R = 0.287 kJ/kg.K and cv = 0.718 kJ/kg.K.
Atrazine is adsorbed to a soil that is only saturated by 5%(i.e. only a twentieth of the pore volume is filled with water), how much atrazine is bound to the soil, dissolved in the water, and present as vapor in the gas phase
Let the noise variance be N0/2 per dimension. Describe a ML detector on this set of M signals.
Tall buildings can develop a significant difference in pressure between the inside and the outside of the building. Air lock entrances are used at the ground level so the pressure at the ground floor is not the same as atmospheric pressure. Assume th..
A supply of geothermal hot water is to be used as the energy source in an ideal Rankine cycle, with R-134a as the cycle working fluid. Saturated vapor R-134a leaves the boiler at a temperature of 180 F, and the condenser temperature is 100 F. Calc..
