  • Use of borosilicate glass powder in cementitious

    Borosilicate glass powder resulted in a 8% increase in the 28 d compressive strength of mortar for the replacement levels of up to 25% by mass. The neutron attenuation coefficient of mortar increased (10–40%) as the amount of borosilicate glass powder increased; however, it appears to plateau when the cement replacement ratio was higher than 25%.
