Silica fume advantages and disadvantages in concrete

Today, silica fume is widely used in the construction industry because its strengths and weaknesses are accepted. What are the advantages and disadvantages of silica fume? Silica fume particles have an average diameter of less than 1 micron. Silica fume is a grey superfine powder with a density of 2. Due to the filling effect of silica fume, the moisture in concrete decreases and local dry shrinkage cracks are caused.

Therefore, strengthening concrete maintenance after construction can effectively alleviate the problem. If the external temperature is too high, it will cause the dry shrinkage of concrete surface.

Before concrete condensation, if the surface water evaporation rate is higher than the bleeding rate, the dry shrinkage crack will appear on the surface. The excessive amount of silica powder will reduce the constructability, make the concrete become compacted, and make the surface of construction difficult. Very low chloride ion diffusion 2. Increased compressive strength 3. Reduced water permeability 4.

Improved sulfate resistance 5. Improved abrasion resistance 6. Improved resistance to chemical attack 7. Improved stability in geothermal environments 8. Reduced efflorescence Silica fume disadvantages include Due to the filling effect of silica fume, the moisture in concrete decreases and local dry shrinkage cracks are caused.
