Are given the results of studies on the creation of samouplotnyayushchikhsya fine-grained fibrobetonov on the withdrawals of lithotrity with the application of a polyfunctional additive D -5. Are developed the compositions of samouplotnyayushchikhsya fine-grained fibrobetonov with the application of a basaltic fibre, which make it possible to considerably decrease the expenditure of cement and to improve the characteristics of fine-grained concrete mixture and concrete. The use of a polyfunctional additive D -5 in the mixtures makes it possible to increase the strength properties of fine-grained fibrobetonov with a simultaneous improvement in the rheological characteristics of concrete mixtures. The replacement of cement to 10 % from the mass by ashes of fraction d0,14 mm in the fine-grained concrete mixtures does not cause noticeable reduction in the strength properties of concrete. Developed samouplotnyayushchiesya fine-grained fibrobetony possess the increased strength properties and have low prime cost due to the use of local raw material and withdrawals of lithotrity

The results of studies on the development of solution mixtures on the withdrawals of lithotrity with the application of pumice and additive D, are represented. Are proposed the compositions of mortars, which make it possible to substantially reduce the expenditure of portland cement and to simultaneously improve the physicomechanical properties of solution mixtures and solution. The application of a multifunctional additive D -5 in the mixtures makes it possible to increase the strength properties of solution with a simultaneous improvement in the rheological properties of solution mixtures. The replacement of cement to 20 % from the mass by pumice of fraction d0,14 mm in the solution mixtures does not cause noticeable reduction in the strength properties of solution. The developed solution mixtures correspond to requirements ALL-UNION STATE STAN. 28013–98 and have low prime cost due to the use of local raw material and withdrawals of lithotrity

Keywords: portland cement, the withdrawals of lithotrity, pumice, additive D -5, transverse strength and compression, the mobility of mixture, exfoliation property, the water-holding ability
