1. how do you determine the absorption capacity of a coarse aggregate?

2. what aggregate property is measured by the los angeles machine?

3. List two types of concrete admixtures and their effects on fresh and hardened concrete properties.

Expert Solution

2. Aggregate toughness and abration characteristics can be determined using Los Angeles machine.

3.

a) Air entraining admixtures:

-> effects on fresh concrete: Air entraining admixtures is replacement of fine aggregate as small bubbles of Air. Air entraining admixtures produce millions of non coalescing air bubbles, which will act as flexible ball bearings and will modify the properties of plastic concrete regarding workability, segregation, bleeding and finishing quality of fresh concrete.

-> effects on hardened concrete: Regarding hardened concrete it's resistance to Frost action and permeability increases.

b) superplasticizers:

-> effects on fresh concrete: It improves the workability of concrete.

-> effects on hardened concrete: Usage of superplasticizers upto certain limit will improve compressive strength after exceeding the limit compressive strength decreases.

Part 1: understanding the AS-AD framework Understand how aggregate supply and aggregate demand determine macroeconomic equilibrium. 1) Draw AD and AS curves where macroeconomic equilibrium occurs at an output of $25 trillion. On your graph, indicate the equilibrium price level (you can assign an exact value). Indicate on the graph where macroeconomic equilibrium occurs. Make sure to label each part of the graph. Part 2: applying the AS-AD framework Evaluate the forces that shape the total quantity of goods and...
