Use of discarded aluminium foil in cementitious material as fire retardant - An experimental study

The research adopts the raw material of 89% slag with the composite activators and the compressive strength, hydration heat, temperature and expansion property of the material are studied. And the new cementitious material is obtained with the properties of low-heat and small expansion, convenience-confect, easy-operation and need no mass production. This material has the remarkable economic profit and good application foreground especially in the mass grouting engineering.

Alkaline Activator

In order to utilize the waste steel slag effectively, three kinds of alkaline activator such as Na2SO4, Na2SiO3, Na2CO3 were used to prepare steel slag cementitious material and measure its strength of 28 days and 60 days in the standard wet conditions. Microcosmic structure form of hydration products of cementitious material was analyzed by the test of SEM. The results indicate that: three activators on the strength of steel slag all have certain stimulation effect, and Na2SO4 has the apparent stimulation effect on the strength of steel slag, the analysis and test of SEM also shows that hydration products structure form of steel slag cementitious material added with Na2SO4 is much more than other two activators and is more helpful to improve steel slag strength.

Maximum Content

In this paper, the performance of steel slag composite cementitious material and the performance of steel slag concrete were studied, which provides reference for the comprehensive utilization of steel slag. The test shows that the activity of steel slag composite cementitious material with the specific surface area is greater than or equal to 400m2/kg to meet the use requirements; When the maximum content of coarse aggregate of steel slag was 25%, the volume stability of steel slag concrete was best. But when the content of steel slag powder was controlled within 30%, the concrete had good resistance to carbonation.
