Abstract：A series of ultra-high performance engineering protective materials with compressive strength higher than 100 MPa is prepared by utilizing composite mineral admixtures(20%–50% mass replacing portland cement)，polycarboxylic type high performance water reducer(water reducing ratio 40%)，short and fine steel fibers on normal shaping and curing condition. Based on the empirical formula，the properties of anti-penetration and anti-explosion of target specimens with different compressive strength(C100，C150，C200) are investigated. The experimental results show that the green ultra-high performance concrete(GUHPC) has excellent performance in anti-penetration and anti-explosion，especially in the C200 target specimens. The corresponding energy dissipation per meter，coefficient of penetration and coefficient of explosion cavity radius are 516 kJ/m，0.389 mm2•s/kg and 0.051 m/kg1/3，respectively. Its ability of anti-explosion is equivalent with reactive powder concrete(RPC)，in addition，the performance of anti-secondary explosion and spalling resistance is excellent.
