As we all know, the basalt aggregates we commonly use in construction projects are widely applied. Have you ever wondered whether the basalt aggregates we use daily are alkaline or acidic? To facilitate your selection, we will now introduce the acidity and alkalinity of this aggregate.
It's well-known that the main component of basalt aggregate is silicon dioxide, along with trace amounts of potassium oxide and sodium oxide. Silicon dioxide makes up around 45% to 50%, indicating that basalt aggregate is an alkaline stone. In contrast, the main component of limestone, which we commonly use, is calcium carbonate, also an alkaline substance.
Detailed introductions have been provided on the acidity and alkalinity of basalt aggregates, so it is crucial for everyone to properly match them in everyday use, thereby enhancing their effectiveness during application.
