Experimental Research on Strengthen Mechanism of NaOH on Light Wall Materials Prepared from Crushed Brick Powder

Abstract:

Crushed brick light weight wall material, which was made of crushed brick as a main raw material and P•S cement as a cementious material. Crushed foam glass and some admixtures were added, is prepared under the ordinary temperature and pressure condition. The main research in this paper is if NaOH has good alkaline excitation on crushed brick light weight wall material through experimental research and mechanism analysis. Studies have shown that: (1) The main chemical composition of crushed brick powder are SiO2 and Al2O3, crushed brick powder have a certain activity.(2) NaOH releases the activity of the internal soluble SiO2 and Al2O3.(3) In this experiment system, when the caustic soda content is about 3%, there has been an obvious peak of compressive strength.
