Sep 01, 2014 · The compressive strength of 28 days aged samples is presented in Fig. 4. The value of the strength varied from 3.35 MPa (talc cement with 0% added MgO) to 4.50 MPa (talc cement with 20% added MgO). The addition of the calcined magnesia (MgO) leads to an increase of the compressive strength. Author: C.J. Ngally Sabouang, J.A. Mbey, J.A. Mbey, Liboum, F. Thomas, D.
