Aggregates are used in two different remarkable sizes to increase the concrete's bulk density. Bigger aggregates are known as coarse aggregate (grit), while the smaller aggregates are referred to as fine aggregate (sand). Fine aggregates that pass through a 4.75 mm sieve are described as 'fine.' These can Received: November 20, 2021

The Aggregate Demand Curve. Aggregate demand, or AD, refers to the amount of total spending on domestic goods and services in an economy. Strictly speaking, AD is what economists call total planned expenditure. We'll talk about that more in other articles, but for now, just think of aggregate demand as total spending.
