Inexpensive intumescent alkali-activated natural pozzolan pastes
, 2015 Perlite, a natural pozzolan, was activated with NaOH to prepare alkali-activated (AA) intumescent pastes. After curing at 100 degrees C for 3-24 h, the solidified pastes had medium strengths, up to 40 MPa, and low densities, similar to 1500-2000 kg/m(3),
