Effects of Activator on the Properties of Brick Powder Foam Concrete Xiang Liu1,a,Yuanjun LI1,b 1School of Architectural and Civil Engineering, Inner Mongolia University of Science and Technology, Baotou 014000, China aiuxiangwd@126.com,b1990liyuanjun@163.com Keywords: Brick Powder Foam Concrete;Activation;Gypsum;Lime Abstract.The main chemical composition of waste brick is silicon dioxide,by means of chemical can stimulate its activity.In this experiment, gypsum, lime sodium hydroxide as activators,through the testing and research about the properties of compressive strength, dry density, water absorption of brick powder foam concrete,analyse the influence of three activators on the properties of foam concrete.The test results show that the:Mixing about 25% lime can guarantee the dry apparent density on the basis of compressive strength increases;Mixing 20% gypsum can make the strength and dry apparent density relatively stable;The incorporation of NaOH make the foam concrete
(3)When NaOH as activator,concrete foam prone to quick solidification phenomenon,not conducive to use in practical engineering; At the same time, the use of NaOH easily contaminate water resources,contrary to the original intention of the utilization of the waste bricks of energy saving and environmental protection,so do not recommend the use of NaOH as a active agent for waste brick .

These transformations are typically enabled by stimuli-responsive materials such as metals, ceramics, and polymers, which can evolve into new configurations over time [1, 2]. 4D printing holds significant promise for applications in aerospace, automotive, and structural engineering.
However, structures composed solely of polymeric materials often exhibit insufficient mechanical performance, such as low stiffness and limited strength, which restricts their practical engineering use and design versatility [3].
