Research on the Effect of the Type of Alkali Activators on the Recycled Mixture of Slag Cement
In order to respond to the requirements of the call for green and environmental-protection engineering,improve the utilization rate of solid waste,and explore the effect of the type of alkali activators on the strength of slag cement,this paper studies the effect of the two alkali activators of NaOH and Na2SiO3 on the performance of alkali-activated recycled concrete formed by the combination of the cementing material and recycled aggregate of slag cement,explores the influence effects of different alkali activators on the mixture from macro and micro views,and determines the best alkali activator suitable for the alkali-activated recycled mixture of slag cement.NaOH,as an alkali activator,is used to improve the defects of slag cement,shorten its setting time and increase its early strength.When Na2SiO3 is used as an alkali activator,the compressive strength and splitting strength of the mixture specimen are the highest at the sodium silicate modulus of 1.0.
