Solar Belite Concrete

Step	Process	Input Material	Local Source (Maysville region)	Output	Notes
1	Quarrying	Limestone (CaCO₃)	Local limestone quarry	Raw limestone rock	Also used later as aggregate
2	Sand sourcing	Silica sand (SiO₂)	Local sand/gravel pit	Raw sand	Must be quartz-rich
3	Coarse crushing	Limestone + sand	On-site	Crushed rock (≤1")	Skid steer crusher sufficient
4	Fine grinding (raw meal)	Crushed limestone + sand	On-site	Fine powder (“raw meal”)	Critical for reaction
5	Blending	Raw meal	On-site	Homogeneous mix	Target CaO:SiO₂ ≈ 2:1
6	Pelletizing	Raw meal	On-site	Pellets/nodules	Improves kiln efficiency
7	Kiln firing	Pellets	Electric kiln	Belite clinker (C₂S) + CO₂	1,250–1,350°C
8	Clinker cooling	Hot clinker	On-site	Cooled clinker	Preserve belite phase
9	Finish grinding	Clinker	On-site	Belite cement powder	Cement-like fineness
10	Aggregate production	Limestone	Quarry + crusher	Gravel + sand	For concrete mix
11	Concrete batching	Cement + aggregate + water	On-site	Fresh concrete	w/b ≈ 0.40–0.47
12	Placement	Fresh concrete	Construction site	Structural element	Foundations, slabs, walls
13	Moist curing	Water	On-site	Hardened concrete	28–56 day strength development
