Test on mechanical capability of steel fiber reinforced cement-base composites

摘要

In order to enhance the mechanics capability of RPC, the tests on the cement steel fiber reinforced cement-base composites with different steel fiber bulk ratio were carried out. Many kinds of strengths of the cement with different steel fiber bulk ratios are obtained. The results show that the enhanced ratio of bending strength is more than that of cleavage strength with the same steel fiber bulk ratio, but the strength is less enhanced when the ratio reaches a certain percentage. The compressive strength becomes also higher with the increase of steel fiber bulk ratio, which is not apparent. The causations worked out through analysis are that the distances between fibers have the important influence on the strength.
