Magnesian Limestone Aggregate In Concrete Agg-Net

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 aggregate absorption value is in the range 4–7% may also be acceptable in many circumstances, however an increased requirement for dust removal is

Archaeologists have, for the last 30 years, been recording the rural archaeology of the Magnesian Limestone belt and adjacent areas in South, West and North Yorkshire. This has occurred in a rather piecemeal way. Initially this was carried out through the air reconnaissance of cropmarks, but more lately through a combination of air photo interpretation and mapping, geophysical survey and

Physical properties of magnesian lime mortars

Magnesian lime is made from dolomitic limestone. The properties of magnesian lime mortars are not yet clearly established: some authors claim that Mg-lime has no hydraulicity and produces poor quality mortars that fracture, while others state that it produces quality hydraulic mortars. Here, Mg-lime was produced by burning magnesium limestone in a traditional limekiln.
