STAPA® Alupor RO are aluminum pastes to produce lightweight concrete (AAC). These pastes are free of water based on diethylenglycol. These products distinguish themselves by increased storage life which makes them particularly attractive for use in warmer regions. the STAPA® Alupor pastes allows for good water wettability and therefore they are easy to disperse. They allow for dust-free processing and are consequently a significant contributing factor to safety. The STAPA Alupor RO 100 is used for high to very high raw densities in formulations with a higher lime-cement ratio.
