New cold mixes components for pavements by product iron ore

Nov 25, 2021 Apaza et al. analysed the incorporation of three different contents (10, 15, and 20% by weight of mixture) of iron ore residue as aggregate in a cold asphalt mixture for micro-surfacing. They pointed out that the mixture made up of 20% iron ore residue performed better in terms of abrasion resistance than those with lower iron content

    Slag cement is as old as iron-making itself. In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s. In the U.S., blends of slag and portland cements were introduced in 1896. Today, slag cement can account for 30% to 50% of the cement
