Study on the Density and Performance of Cementitious Materials Compounded by Multiple Mineral Admixtures
This paper studies on the relative denseness of fresh cement pastes compounded with multi-cementitious materials and the performances of their harden concretes. Results show that with the dense packing of several ultra-fine particles, higher the relative denseness of different cementitious material system, higher the compressive strength and lower the air permeability of the harden concrete. The multi-cementitious material compounded by 37% cement、20% fly ash、40% pulverized slag and 3% silica fume has the higher relative denseness of fresh cement paste, and its compressive strength and air permeation of harden concrete composite is also improved.
