Not only does the rain cause standing water, but the limestone is also wetter coming out of the ground. Little of that water is lost in the crushing process, and dry material can absorb moisture as it is reduced in size. So in the winter months, by the time the material lands in the 486 t limestone silo, it is nearly saturated. In prior years

28.10.2021It takes a long time for the cement to hydrate and harden and needs enough water to ensure hydration. For ordinary Portland cement, the addition of gypsum is kept between 3% and 4%, while for quick-setting cement, the gypsum addition can be 2.5%.
