Normal hemostasis requires free ionized calcium for the initial platelet plug formation and also for most events in the blood coagulation process. Calcium is essential for normal platelet adherence and for the subsequent spreading of platelets on the sub endothelium. Blood clotting process involves both intrinsic and extrinsic pathways.

These pathways converge to a common point, the formation of the Factor Xa/Va complex which together with calcium and bound on a phospholipids surface, generate thrombin (Factor IIa) from prothrombin (Factor II) . Coagulation is the push-off-the-cliff that turns milk into cheese. Liquid milk is converted into a solid mass. This solid mass is often called “curd”, “gel” or the “coagulum”. Coagulation can occur in a few different ways: enzyme action, acid addition, or acid/heat addition. When tissue extracts and calcium chloride (CaCl 2) are mixed in optimum amount of blood of normal fibrinogen content, they only factor which has an inadequate concentration of prothrombin can very the coagulation time.

It will help establish proper pH of the mash and the wort and provide sufficient calcium ions essential for enzyme function, kettle protein coagulation and yeast 

Thrombin acts as a catalyst to convert the soluble plasma protein fibrinogen (‘giving birth to fibrin’) into the insoluble, stringy plasma protein fibrin. The fibrin threads entangle the blood cells and create a clot. Hypercalcemia is a condition in which you have too high a concentration of calcium in your blood. Calcium is essential for the normal function of organs, cells, muscles, and nerves.

Coagulation and flocculation occurs in successive steps, allowing particle collision and growth of floc. This is then followed by sedimentation (see Sedimentation Chapter). If coagulation is incomplete, flocculation step will be unsuccessful, and if flocculation is incomplete, sedimentation will be unsuccessful.
