EVALUATION OF LIMONITE CONCRETIONS BY
limonite weathers. In the past limonite was also referred to as swamp ore, brown hematite, brown ironstone, hydrogoethite, etc. There are several types of limoniteThe mineralogical characteristics indicated that Mn goethite was present as nano-granular (<15 nm) or acicular (50–100 nm long, ~10 nm wide, i.e. high Mineralogy and Geochemistry of Limonite as a Weathering

Hematite Common Minerals
Goethite (a.k.a. Limonite): Goethite is a hydrous (water-bearing) iron oxide that forms as a direct precipitate in marine water and bogs, and as an alteration of other iron-bearing minerals. Along with hematite, goethite is the other mineral that makes up most of the rust on natural and artificial iron exposures.Reference [] developed bulk concrete mixtures with varying water/cement ratio’s ranging 0.3–0.6 to find out the ultimate appreciable water/cement ratio of bulky concrete yielded with barite.Also, there was a utilization of two different types of cement that is PKC 32.5 and PC 42.5 in the experimental analysis.
