combinations of Magnesian limestone coarse aggregate and natural sand; wide variations in the strength and porosity of the coarse aggregate have minimal effect. —Crushed Magnesian limestone sands are suitable for use in concrete, especially those from sources where the coarse aggregate absorption value is less than 4%. Sands from sources where the coarse

Magnesian Limestone Aggregate In Concrete | Agg-Net

On average, the Magnesian limestones were significantly harder and less porous than the Jurassic limestones, and some of them had properties similar to Carboniferous limestones. Nevertheless, quite a few were extremely weak and porous. In several quarries different horizons had very different properties, but the lateral variation was found to be fairly small. Sometimes …
