Make Water Soluble Calcium At Home | Growing Organic
Believe it or not, calcium is as essential for plants as it is for humans. It is commonly found in nature and is second to being as common as oxygen. In the form of calcium carbonate, calcium can be extracted from something as common as eggshells when paired with vinegar. Natural and organic farmers, even gardeners, tend to create their own water soluble calcium at home.

Effect of nano-sized calcium carbonate on cure kinetics
It can be suggested that the improvement in the pull-off strength of the filled polyester/epoxy system is due to the presence of nano-sized and well-distributed calcium carbonate particles which can minimized the porosity of the coated films and thus it depicts better adhesion performance compared to the neat system.

MECHANICAL AND MORPHOLOGICAL PROPERTIES OF POLY (LACTIC
fiber, calcium carbonate (CaCO3) have poor mechanical properties due to the poor interfacial adhesion. Maleic anhydride grafted PLA (PLA-g-MA) has been used to improve the interfacial adhesion between PLA and other polymers [6, 7, 8] or PLA and fillers [9, 10, 11]. CaCO3 is selected in this study since it yields a cost reduction in polymer
