Apr 01, 2013· Its production is about 4–5 tons for each one ton of phosphoric aside produced in the factory (Odat et al., 2008). Sulfuric acid is added to limestone to produce phosphoric acide. As a result hydrate calcium sulfate is produced (phosphogypsum, CaSO 4 ⋅2H 2 O). Natural gypsum (NG) is usually added to cement in the final stage of cement ...

Aug 28, 2001· Phosphogypsum (PG, CaSO4·H2O), a byproduct of phosphoric acid manufacturing, contains low levels of Ra226. PG can be stabilized with portland type II cement and class C fly ash for use in marine environments, thus eliminating the airborne vector of transmission for radon gas. An augmented simplex centroid design with pseudocomponents was used to select 10 PG:class C fly .
In 2007, the output of natural gypsum in China was more than 50 million tons (of which 35 million tons was used for cement retarder and the others were converted to hemihydrate gypsum or gypsum board), so that even if all the chemical gypsum was completely replaced The natural gypsum, there may still be tens of millions of tons of gypsum and ...
Jun 27, 2012· The utilization of the phosphogypsum (PG) as cement retarder is both an economical and an ecological approach to treat this solid waste. Cement using raw PG as retarder has two problems pressing for solution,namely, delaying the setting time and difficulty being fed into the cement mill. The soluble phosphates in PG behave as superretarder and bring about retarding in the setting process .

The paper presents the research and engineering experience in the calculation and design of concrete structural elements, reinforced by fiberglass rods. The construction of a concrete beam reinforced by fiberglass rods is presented. Research in preserving prestressing forces in a beam subjected to weathering for about 30 years is considered.
