Working with silica-fume concrete
silica-fume concrete Improving concrete with silica fume requires using the correct placing, finishing, and curing procedures Construction workers must be carefully trained to get the best results with silica-fume concrete. There is little or no bleeding in flatwork, so finishers must adjust the timing of finishing operations.
How microsilica improves concrete – Concrete Construction
microsilica concrete and a low-slump dense concrete without microsilica, both compounded for bridge deck overlays. Early strength of the microsilica concrete is lower. But after two days, values are about equal. After 28 days, microsilica concrete is about 40 percent stronger and after 56 days, 50 percent stronger (from Reference 2).
