The best nutrient utilization in the diet with phytase addition was evident especially in the last two phases, in which the phytase 1,500+MT C (reduction of 0.225% avP; 0.245% Ca; and 0.053% Na, with 1,500 FTU/kg phytase) did not decreased broiler performance, enabling partial and total replacement of dicalcium phosphate on starter, grower and finisher phases, respectively.
This may be because, with a reduction in the cement-sand ratio, the hydration reaction gradually proceeded toward the hydration reaction of dicalcium silicate.
The ionic products of plasma-sprayed dicalcium silicate coating are beneficial to the proliferation and differentiation of MG63 osteoblast-like cells, and they differentially regulated osteoclastogenic gene expression by upregulating OPG and downregulating RANKL [16, 17].
Neo MTA Plus cement is a dicalcium silicate-based powder-gel system that may be used as restorative or endodontic cement with varying powder-gel ratios.

Dicalcium silicate also affects the strength of concrete through its hydration.

In the present study, three basic powders have been used which are dicalcium silicate ([C.sub.2]S), tricalcium phosphate ([C.sub.3]P) and zinc oxide (ZnO).

By contrast, acidic calcium phosphates, dicalcium phosphate anhydrous (CaHP[O.sub.4] , DCPA, Monetite) and dicalcium phosphate dehydrate (CaHP[O.sub.4]-[H.sub.2]O, DCPD, Brushite), are more degradable at physiologic pH than HA and will form a [Ca.sup.2+] and P[O.sub.4.sup.3-] supersaturated zone at the interface of implant and bone that may induce osteoblastic differentiation [6].
