History of Cement | Construction Materials
Cement as we know it was first developed by Joseph Aspdin, an enterprising 19th-century British stonemason, who heated a mix of ground limestone and clay in his kitchen stove, then pulverized the concoction into a fine powder. The result was the world's first hydraulic cement: one that hardens when water is added.

Improving Your Clay Soil By Adding Lime – A Complete Guide
— When To Add Lime To Clay Soil. Lime can be added to clay soils any time of the year, but the best time is in the fall. This gives it a chance to start working over the winter before spring planting. Lime moves down through the soil slowly so it needs time to incorporate. Apply lime at least 2-3 months before growing plants that need high pH levels.
