| Abstract: | Based on the principle of DSP,some measures were taken,such as adding silica ash,ultra-fine powder,and nano-SiO2 were dispersed into the porosity between cement and silica ash.The highest density was achieved.The influences of type of cement(C) and high-range water reducer(HRWR) on compressive strength are evaluated.Through a large number of experiments,an ultrahigh performance cementitious materials with a 1 d compressive strength of 62 MPa and 28 d compressive strength of 165 MPa was successfully develope... |
