Covered Drying for Green Bricks: How Much Roof per Thousand Bricks Keeps Rain Losses Below Fuel Savings

This paper addresses green bricks ruined by rain during open-air drying in wet seasons. It presents a covered-drying sizing rule expressed as roof area per thousand bricks, derived entirely from stated assumptions and a computation whose code and full output accompany the paper. The sweep covers covered fraction of drying yard from 0 to 1. The headline outcome is: best x 0.6; best total usd 152.5; total uncovered usd 198; total full cover usd 178; bricks lost at best 628; bricks lost uncovered 2200. These figures identify a specific operating point or bound that a workshop can apply directly, and they also show how quickly performance deteriorates away from it. No kiln was built, no ware was fired, and nothing was measured for this study. SIMULATED, NOT MEASURED.
