What's the Deal with 96% Undensified Microsilica?
Microsilica, also known as silica fume, is a byproduct of the production of silicon metal and ferrosilicon alloys. It is a highly reactive mineral admixture that is used to enhance the properties of concrete. One of the most important properties that microsilica improves is the strength of concrete.
The strength of concrete is directly related to the amount of cementitious materials present in the mixture. Cementitious materials include cement, fly ash, slag, and microsilica. Microsilica is able to improve the strength of concrete due to its high reactivity. When microsilica is added to the mixture, it reacts with the cement to produce additional calcium silicate hydrate (C-S-H) gel. The C-S-H gel is the primary binder in concrete and is responsible for its strength.
However, not all microsilica is created equal. Microsilica can be classified as either densified or undensified. Densified microsilica has particles that are closely packed together, while undensified microsilica has particles that are more loosely packed. The degree of densification affects the reactivity of microsilica. Undensified microsilica is less reactive than densified microsilica.
So, what's the deal with 96% undensified microsilica? 96% undensified microsilica is a type of microsilica that has a purity level of 96%, but its particles are less densely packed. This means that it is less reactive than densified microsilica, but more reactive than other types of undensified microsilica. .
The use of 96% undensified microsilica in concrete has several benefits. First and foremost, it provides a cost-effective way to increase the strength of concrete. 96% undensified microsilica is less expensive than densified microsilica, but still provides a significant boost to strength. Additionally, the lower reactivity of 96% undensified microsilica can be an advantage in some situations. For instance, it can be used in hot weather conditions to extend the working time of the mixture.
In conclusion, 96% undensified microsilica is a type of microsilica that has a purity level of 96%, but its particles are less densely packed. While it is not as reactive as densified microsilica, it still provides a cost-effective way to increase the strength of concrete. The use of 96% undensified microsilica in concrete has many advantages, and it is an important ingredient for enhancing the properties of concrete.
