Product Info
Impact of aspha-min®:• Added to the mix shortly before or at the same
time as the binder at a rate of 0.3% by mass, the zeolite starts to release water, creating a very fine water spray
• This controlled foaming effect leads to a slight increase of the binder volume
• The gradual release of the water provides the impact over a longer period of time (6 to 7 hrs.)
• The effect lasts until the mix has cooled to (212° F) thus ensuring comfortable workability of the mix
