Effect of temperature and slag powder on the cement-based ternary system
Source abstract
Abstract
Portland cement–aluminate cement–gypsum is a very complex gelling system and is currently widely used in various repair projects. Due to the influence of the construction environment, the system is greatly affected by temperature, and the main hydration product, ettringite, is volatile. Therefore, to test the fluidity, setting time and compressive strength of the ternary system at 20, 40 and 80°C, slag powders were added to study the influence of different curing temperatures and slag powders on the performance of the ternary system and X-ray diffraction was used to analyze the change mechanism. Due to the high temperature resistance and micro-aggregate effect of the slag powder, the high temperature strength loss of the ternary system was effectively compensated by the slag powder with the increase of temperature.
