Why GP Group invested GP Group started looking to build its limestone activities outside of Thailand and partnered with the Al Rawas family in Oman to secure a one billion tonne reserve of very high quality limestone (about 98% calcium carbonate).
A number of attempts have been made to classify water hardness. Water with hardness values greater than 150 mg L −1 is designated as very hard. Soft water has values of less than 60 mg L −1.Groundwaters in contact with limestone or gypsum (CaSO 4.2H 2 O) rocks can commonly attain levels of 200–300 mg L −1.In water from …

One popular method is the use of pink limestone to make limestone water. The natural mineral water is often used in cooking fried food or pickling. The natural characteristics of the limestone water yield a crispy texture. Other limestone powders can be dissolved into water to provide calcium and mineral support.
Water can deteriorate the compositional properties of rock through softening and dissolution. The water content rate of rock has a certain effect and can cause changes in rock properties caused by the water action. In this research, to study the effects of the water content rate on the strength and brittle plasticity of limestone, uniaxial …
