Effect of cattle manure ash on workability and mechanical properties of magnesium phosphate cement

Cattle manure ash (CMA) is an industrial waste produced from the combustion of cattle manure. This research examined the effect of added CMA produced at combustion temperatures of 500 °C, 650 °C and 800 °C on the workability and mechanical properties of magnesium phosphate cement (MPC). The obtained data indicates that CMA decreases workability and mechanical properties of MPC to which it is added. However, relatively higher combustion temperature in CMA preparation can diminish the adverse effect that CMA exerted on mechanical properties and workability of MPC. CMA promotes the formation of struvite in the hydration reaction of MPC.
