The art of mixing cement

Ijigu supervises, as Gazan and Debebe prepare aan aggregate and cement blend for portland cement.  Depending on where the concrete is being used, cement to aggregate ratios are anywhere between 6 to 1 to 8 to 1.  Everything is mixed by hand. So far we have gone through over 130 bags of cement and more than 4 dump trucks of aggregate.
