Abstract

In this study, we investigated hydrogen-peroxide foamed cement foams to which we used sodium-lauryl-sulfate (SLS) as a foam stabilizing additive. The specimens were pre-pared cement, water, hydrogen peroxide, expanded perlite and the aforementioned foam sta-bilizer. The substances listed were applied in two series. In one the amount of foam stabilizer additive was 0.01 wt%, while in the other it was twice 0.02 wt% relative to the weight of the cement. The samples were foamed with a 30% hydrogen-peroxide solution in 4 wt%, 6 wt% and 8 wt%. As a result, we obtained specimens with a body density of 450–660 kg/m3. The prepared samples had 0.89–2.24 MPa compressive strength on the 28th day. In addition, we examined the macro structure of the specimens.
