摘要

This article deals the effect of oxygen plasma modification on mechanical properties of lightweight cement matrix. There is also described the process of plasma modification. Test specimens contain polypropylene microfibers, cement, recycled concrete, foaming agent and mixing water. Two sets of lightweight test samples with different density and a set of non-lightweight samples were made. To determine the effect of the plasma modification on the mechanical properties of the resulting cementitious composite, the samples were divided into two groups. Half of the samples contain oxygen plasma treated microfibers; the other half of the samples have the same composition but contain microfibers without plasma treatment. The mechanical properties of the test specimens were measured and the compressive strength of samples containing plasma modified fibers were compared with samples containing fibers without plasma modification.
