What is the effect of adding silica to concrete?
Introducing silica into cement-based material concrete in a more uniform manner can improve its physical and mechanical properties. Adding silica and PC modified products to concrete under certain conditions can effectively improve the workability and mechanical properties of cement paste and mortar. That is to say, the addition of silica can improve the physical and mechanical properties of concrete. Moreover, black carbon black can also be added to concrete, and its main function is coloring.
What is the dosage of black concrete carbon black?
The amount of carbon black in concrete depends on the strength grade of the concrete label. For example, if concrete is used to restore asphalt pavement, the color is inconsistent.
