presence of dolomite additive. It means that there is no especially retarded setting at additive up to 30% cement replacement. One can see (table 2) that the total heat related to the amount of neat cement is higher in the pastes with dolomite. It means that the hydration of cement is accelerated in the presence of additive. The same effect is

Replacement of cement with dolomite powder is found to improve the strength of concrete. The maximum replacement percentage of cement with dolomite powder is found to be 5% and at this replacement level, the maximum increase in the 28th day compression and flexural strength were found to be 5.84% and 2.73% respectively.

D111 is a liquid thixotropic additive that helps manage lost circulation during cementing from offshore platforms or any other location where the handling of solid additives is impractical. Because it can be easily used with any portland cement, D111 improves performance and reliability as compared with conventional thixotropic additives that ...
Calorimetry was applied to follow the hydration in the Portland cement–dolomite–limestone mixtures. In the experiments the limestone additive of various fineness (standard component of various common cements), as well as the dolomite additive (not a standard component) were used. The rate of hydration versus time for common cements reflects the proper setting and early hardening during the ...
Diatomite is available in grey, white, yellow colors whereas, Dolomite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Diatomite is Soft and that of Dolomite is Glassy or Pearly. Properties of rock is another aspect for Diatomite vs Dolomite. The hardness of Diatomite is 1 and that of Dolomite is 3.5-4.
