Flexural strength of cement paste composites containing micron and sub-micron nickel particulates
The effect of nickel particle addition (0.3 microns to 5.0 microns diameter) to brittle cement paste matrices on flexural strength was investigated. Strengthening was observed for nickel particle addition up to 15 % by volume. Addition of micron and sub-micron size nickel particulates to brittle cement paste matrices can increase flexural strength. Porosity is reduced by approximately 15 % with the addition of 10 percent (by volume) of nickel particles. The volume of large pores (0.009 microns to 0.017 microns) is reduced and the volume of fine pores (0.004 microns to 0.005 microns) is increased. Reduced porosity and toughening mechanisms e.g. crack pinning and bifurcation would appear to result in strengthening of brittle cement matrices.
