Test method for rheological behavior of mortar for building work

Korobko B., Vasyliev I.

Acta Mechanica et Automatica

2017

Vol. 11, no. 3

173--177

This paper offers a test method for rheological behavior of mortars with different mobility and different composition, which are used for execution of construction work. This method is based on investigation of the interaction between the valve ball and the mortar under study and allows quick defining of experimental variables for any composition of building mortars. Certain rheological behavior will permit to calculate the design parameters of machines for specific conditions of work performance – mixing (pre-operation), pressure generation, pumping to the work site, workpiece surfacing.

The use of biofuel on the railway transport

Mogila V., Vasyliev I., Nozhenko E.

Transport Problems

2012

T. 7, z. 1

21-26

The potential of biofuel application on rail transport for reducing the dependence on using the non-renewable diesel fuel and improving the environmental characteristics of the locomotive have been considered. The technique of comparative research concerning fuels on the rheostat and through operational tests has been offered. The methods of measuring harmful emissions with exhaust gases and the use of existing methods of controlling the fuel consumption have been developed. The conclusion about the prospects of using on diesel locomotives first the additives to the diesel fuel the biofuels of the first generation (biodiesel), and in future, the fuel of the second generation (synthetic biofuels) has been made.
