A new type of concrete mineral admixture:Super-fine active silica powder(SSP) was studled.First,the pozzolanic activity of SSP was determinded by the method of motar strength.Subsequently,a series of different mineral admixture and content concrete experiments were been tested.Finally,the content of CH in the different types of concrete was compared by the method of XRD.Test result shows that:SSP has a very high pozzolanic activity;conditions in the appropriate mixing amount,SSP can… CONTINUE READING
