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).

Quadratic production and restricted profit functions are estimated using farm-level survey data from Ethiopia in 1994. The results indicate that farmers respond only modestly to price incentives. The own-price output supply elasticity is very low and output supply is not responsive to fertilizer prices or the wage rate.
