Abstract:
To establish the calculation method for local compression bearing capacity of reactive powder concrete(RPC),the axial local compression experiments on 48 RPC prism specimens are completed.The influences of strength of RPC and the local compression area ratio on local compression performance of RPC are researched.Experimental results show that the strength grades of RPC have a little influence on local compression enhancement coefficient and the coefficient increases with the increase of the local compression area ratio.Under the same local compression area ratio,the local compression enhancement coefficient of RPC is lower than the high strength concrete.Based on the experimental results,two kinds of calculation formulas for local compression bearing capacity of plain RPC and RPC with steel fiber are brought forward.All these can be served as references when revising the relevant design standards.
