SPECIFIC SURFACE OF HARDENED PORTLAND CEMENT PASTE AS MEASURED BY LOW-ANGLE X-RAY SCATTERING

LOW-ANGLE X-RAY SCATTERING OFFERS THE POSSIBILITY OF MEASURING THE SURFACE AREA OF CEMENT PASTE IN A MANNER NOT SUBJECT TO THE ASSUMPTIONS INHERENT IN ANALYZING SORPTION DATA, AND IS FREE FROM THE POSSIBILITY OF SPECIFIC INTERACTIONS BETWEEN ADSORBENT AND ADSORBATE. FURTHER, IT PERMITS SPECIFIC SURFACE MEASUREMENTS TO BE MADE ON SATURATED, I.E., UNDISTURBED SAMPLES. NITROGEN ADSORPTION MEASUREMENTS FAIL TO REGISTER MOST OF THE SURFACE THAT IS PRESENT IN CEMENT PASTE. WATER VAPOR ADSORPTION MEASUREMENTS ARE COMPARABLE IN MAGNITUDE TO THOSE OBTAINED BY X-RAY SCATTERING FOR DRIED SAMPLES.
