รายละเอียดเพิ่มเติมPortland cement takes quite long to cure. I let it sit on the ball for three days and then I carefully placed the ball upside down so the cement was at the bottom side and I removed the ball. That was easy because the plastic did not stick the the ball. Then I also removed the plastic and let the cement dry further for another 5 days.

รายละเอียดเพิ่มเติมPortland cement must not exceed 400 lb/cy proportionally, and only comprise 50% max by mass of the total cementitious materials content. This is meant to encourage use of mineral admixtures and cement replacers. The water to cement (w/c) ratio must be 0.35 or greater. Water pre-absorbed by the aggregates is not considered part of the w/c ratio.
