Chapter 231: Stumped at the First Step
Su Bai sat at the wooden table, twirling the pencil in his hand, pondering over the production of cement.
He pursed his lips and furrowed his brow, looking troubled. After all, cement was not something that could be easily produced.
Cement was one of the most common building materials, essential for construction.
[Generally, cement is divided into three types: ordinary silicate cement, silicate cement with mixed materials, and special cement…] Su Bai thought with a frown. He picked up the cup on the table, about to take a drink when he realised it was empty. Also, they were not done boiling the water.
He now missed the fox eared girl a bit, after all, back in the Tribe, he could easily get a full cup of water at any time.
Su Bai sighed at this thought, realising he’d have to wait a few days until the fox eared girl arrived.
He asked a nearby slave to check if the water had boiled yet, while he continued to contemplate the components of cement.
[The main components of ordinary silicate cement are limestone, clay, and iron ore powder…] Su Bai wrote on the Wolf Tail Grass Paper. Ordinary silicate cement was made by finely grinding and mixing limestone, clay, and iron ore powder in a specific proportion. The mixture at this stage would be called raw material. Once the raw material was calcined, usually at a temperature of about 1450 degrees, the product after calcination was called clinker.
Clinker would be finely ground with gypsum, mixed in proportion. Only after this step could the final product be called cement.
[For silicate cement with mixed materials, I would need limestone, clay, iron ore powder, and the mixed materials…] Su Bai continued.
