The mix ratio for Hollow Concrete Block (HCB) production in Ethiopia is a critical factor in ensuring the blocks' quality and strength. Typically, a mix ratio of 1:5 to 1:6 is commonly used, indicating one part cement to five to six parts aggregate (a combination of sand and crushed stone or available raw materials based on the region).

In many applications, we want to understand how the aggregate production function responds to variations in the technology or other inputs. This is illustrated in Figure 16.9.An increase in, say, technology means that for a given level of the capital stock, more output is produced: the production function shifts upward as technology increases.

An aggregate production function relates the total output of an economy to the total amount of labor employed in the economy, all other determinants of production (that is, capital, natural resources, and technology) being unchanged. An economy operating on its aggregate production function is producing its potential level of output.
