Influence of Mixing Factors on the Early-Age Properties of Magnesium Potassium Phosphate Cement Mortar
Kang, Suk-Pyo; Kim, Jae-Hwan;
In early applications of Magnesia-phosphate cements (MPCs) in civil repair engineering, ammonium dihydrogen phosphate(ADP) was usually used as the phosphate component. the ADP-based MPC can be termed as magnesium ammonium phosphate cement (MAPC), However, as the byproduct of the reaction forming struvite, ammonium gas would generate an unpleasant odor, leading to attempts to replace ADP by potassium dihydrogen phosphate(KDP), The KDP based MPC can be termed as magnesium potassium phosphate cement(MKPC). The properties of magnesium potassium phosphate cement (MKPC) mortars with different potassium phosphate to magnesia (KDP/MgO) weight ratios and water to binder (W/B) weight ratios have been investigated. The experimental results show that both KDP/MgO and W/B ratios have large influence on the setting time and mechanical properties of MKPC mortars. Therefore, the formulation has to be optimized in terms of the workability, performance, as well as cost consideration.
