Resum
This research work aims to study the porosity of these CBPC formulated with LG-MgO as a function of the amount of setting retardant admixtures, such as boron compounds or polyphosphates. These additives improve the fluidity of the fresh paste and its workability, shifting the equilibrium of acid - base reaction between the metal oxide and the phosphates. By this way, the initial setting time can be delayed and the release of the heat flux from exothermic reaction decreased. Both parameters have ...
