Phosphate rocks: Phosphorus, an element of phosphate, strengthens roots and helps them to mature early. Table 7.6 shows the rock phosphate analysis which contains 26.7% P 2 O 5.Rock phosphate is recommended in organic farming as a source of phosphorus for plants.
Note: Soft Rock Phosphate does not contain soluble phosphate, therefore the phosphate availability is a function of acid soil conditions and/or active soil biology, i.e. soft rock phosphate becomes available rapidly in acidic soils. In alkaline soils, it should be combined with REGYP compost, humates, microbial agents.
An article of manufacture including reinforcement material embedded in a phosphate cement composition is provided. The phosphate cement composition includes about 10 to 40 percent by weight calcium or magnesium oxide, about 10 to 40 percent by weight acid phosphate, and about 10 to 50 percent by weight vermiculite or perlite or mixture thereof.

Sep 23, 2011· High-Early-Strength Magnesium Phosphate Cement with Fly Ash. The microstructure and properties of a novel magnesia phosphate cement (MPC) with large amounts of fly ash were studied in the present work. For comparison purposes, reference specimens without the incorporation of fly ash were also investigated.
Feb 07, 2003· In addition, removal of set phosphate cement excess was perceived as being easier to do with zinc phosphate cement than with resin cements. As a consequence, dentists felt more comfortable with using zinc phosphate and glass ionomer cements, something that facilitated the introduction of Procera crowns.
phosphate ion interaction in concrete, it is necessary to take into account other mutual interactions between phosphate compounds, concrete constituents and other external chemical species. Regarding this topic, the possible synergic action of phosphate and sulfate-based pollutants toward the alteration of cement-based materials needs to
Meeting future demand for rock phosphate, the key raw material of fertilizer, is expected to be difficult due to continued oligopoly caused by the small number of producing countries, scarcity of resources, and the export limits imposed by China, the largest producing country in the world.
