“…In early application of MPCs in engineering, ammonium dihydrogen phosphate (ADP) was used as the phosphate component in the MPCs system [11]. However, subsequent study indicated that ADP-based MPCs release a large amount of unpleasant gas ammonia, which restricts it to outdoor applications and led to attempts to replace ADP by potassium dihydrogen phosphate (KDP) [12][13][14]. In addition, sodium dihydrogen phosphate (SDP) was also reported to substitute ADP for academic research [15].…”

“…The immersed mass (M 2 ) and the wet mass (M 3 ) were determined after the specimens were immersed in water for 1 h and fully saturated. Therefore, the apparent porosity (P A ) and the bulk density (D A ) were respectively calculated according to Eqs (6) and (7)326:…”

High-porosity magnesia phosphate paste (HPMPP) was prepared via the pre-foaming method. In the pre-foaming method, sintering treatment was not required. The bulk density and maximum compressive strength of the HPMPP prepared according to the ratio of water to solids (W/So) of 0.32 reached 464.00 ± 5.00 Kg/m3 and 0.30 ± 0.05 MPa, respectively. The compressive strength increased with the increases in the addition amounts of sodium silicate and polypropylene fibers. The bulk density of HPMPP increased with the increase in the addition of sodium silicate and decreased with the increase in the addition of polypropylene fibers. Besides, the porosity of the magnesia phosphate paste increased from 79.85% to 81.27% and from 80.31% to 83.75% after the addition of sodium silicate and polypropylene fibers respectively. The highest porosity (83.75%) of the prepared HPMPP was realized under the addition proportion (sodium silicate: polypropylene fibers: solids = 0.06:0.0025:1). The average pore size of the prepared HPMPP is about 180 μm and the pore distribution range is relatively narrow. The hydration product (struvite) is combined with MgO particle one by one and then coated on the surface of bubbles. With the decrease of the water content, after breaking bubbles, the porous structure can be achieved.

“…A. Wang, Yuan, et al (2013) calcined the MgO (1 200 • C) for 3 hours and dried particles of KH 2 PO 4 (100 • C) as acidic component for 6 hours. Then, by grinding, they pre-mixed the two components and dried them for 3 hours forming a powder compound (grams) that was mixed with deionized water in different proportions.…”

Phosphate cements originated more than a century ago for specific applications to the field of dentistry. These cements have other applications including: biomaterials with bone applications, stabilization of hazardous waste, and structural cements. However, the applications in civil infrastructure are recent and not widely known. Therefore, this review discusses and analyzes phosphate cements, presenting the most significant findings of the research to address their mechanical behavior of these cements. It also describes the impact and application of phosphate cements as a structural product (pastes, mortars and concretes), in addition to typical values of mechanical strength, workability, commercial applications, etc. As a result, the review allows to elucidate advantages and disadvantages in comparison with existing technologies and the mechanical possibilities of these cements as biomaterials and for the immobilization of radioactive waste.
