The results of studies on the development of composition gypsum solution mixtures on the pumice with the application of a multifunctional additive D, are represented. Are proposed the compositions of mortars on composition gypsum that binding and ashes, that make it possible to substantially improve the physicomechanical properties of solution mixtures and solution. The introduction of multifunctional additive D -5 to solution mixtures makes it possible to improve the properties of composition solution mixtures. The developed composition gypsum solution mixtures correspond to requirements ALL-UNION STATE STAN. 28013–98 and have low prime cost due to the use of the pumice
