Fin (geology) - Wikipedia

Sandstone is bedded, which provides zones of weakness, along which weathering and erosion takes place Iron oxide and calcium carbonate cemented sandstones produce fins These are typically seen as weak cements, compared to the erosion resistant silica cement, but in arid and semi-arid regions they are much more resistant...

Concrete Coloring with Iron Oxide Pigment

When cement, water and iron oxide pigment are present together, water is preferentially absorbed by the cement leaving the pigment in a semi dry stage This state encourage the clumping together of the pigment particles forming dry balls This condition of "BALLING" will not breakup totally during the short mixing cycle of the concrete...

Cementation (geology) - Wikipedia

Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains The new pore-filling minerals forms "bridges" between original sediment grains, thereby binding them together In this way sand becomes "sandstone", and gravel becomes "conglomerate" or "breccia" Cementation occurs as part of the ,...

Sedimentary rock - Sandstones | Britannica

Sedimentary rock - Sedimentary rock - Sandstones: Sandstones are siliciclastic sedimentary rocks that consist mainly of sand-size grains (clast diameters from 2 to 116 millimetre) either bonded together by interstitial chemical cement or lithified into a cohesive rock by the compaction of the sand-size framework component together with any interstitial primary (detrital) and secondary ....
