Calcium aluminoferrite has little effect upon the physical properties of cement. On hydration it forms  : 175 4CaO⋅Al 2 O 3 ⋅nH 2 O and hydrated iron oxide gel. In principle, this is a fast and energetic reaction, but precipitation of an insoluble layer of hydrated iron oxide upon the calcium aluminoferrite crystal surface forms a barrier to further reaction.

Daily urinary calcium loss varies according to the calcium intake amount: values in excess of 7.5 to 8.5 mmol per day (300–340 mg/day) are typically regarded as representing hypercalciuria. Serum ionized calcium concentration is controlled largely through the action of parathyroid hormone (PTH), an 84-amino-acid polypeptide with a circulating t½ of 3 to 4 minutes.

What is the formula for the ionic compound composed …
Ca_3(PO_4)_2 Well, the name will be simple, as by ionic bonding rules, we first write down the name of the ion, in this case calcium, and then the name of the anion, which in this case is phosphate. The name is thus: calcium phosphate Now, we need to criss-cross to get the chemical formula. Calcium usually exists in its +2 state, while a phosphate ion has a -3 charge. So, we get: Ca^(2+)PO
