UG-Mat Coal Bottom Ash/Boiler Slag Recycled Materials

Obtaining adequate compaction is essential with boiler slag mixtures. Optimum compaction is produced by blending boiler slag with well-graded, angular, rough-textured aggregate and limiting the percentage of boiler slag to 50 percent. Porous boiler slag can be used in greater percentages, but excessively porous slag are weak and can crush.

Effect of Silica Fume on Steel Slag Concrete ethesis

Steel slag aggregate generally exhibit a propensity to expand because of the presence of free lime and magnesium oxides hence steel slag aggregates are not used in concrete making. Proper weathering treatment and use of pozzolanic materials like silica fume with steel slag is reported to reduce the expansion of the concrete.
