Investigation into porous concrete formation peculiarities with a mixed binder composition/Dujų betono su mišria rišančiąja medžiaga formavimo ypatumų tyrimai

Abstract

Porous concrete is a cheap material produced from local raw materials. That is why, it is important to improve it's properties, especially the product's density.


This paper deals with porous concrete made using a mixed binder composition (lime+Portlandcement) formation peculiarities and determination of optimal product formation parameters for 300–350 kg/m3product dependency on the binder mixture composition. A wide density interval (200–500 kg/m3) was investigated to determine the optimal above mentioned porous concrete density parameters.


It was determined, that the porous concrete density with a mixed binder composition has a complex dependency from water and dry solids ratio (V/K), mixed binder composition and amount of Al powder.


Mathematical equations of porous concrete density on technological parameter were derrived. It was found that the lime contant increase in the lime- Portlandcement binder mixture, lowers Al powder effectiveness, increases the product's density and decreases the technological operation time duration.
