They can be classified as one or the other by looking at the characteristics of gas bubbles found within the ejected magma- in explosive eruptions, the gas bubbles, or vesicles, rapidly expand to fragment the magma, which degasses as it cools to form pumice.
The scientists suggest that the bubbles in the magma turned it into a buoyant foam that rose to the seafloor, where it turned into molten pumice 'balloons' and continued to ascend to the sea surface.
The reason for this is advanced construction technologies and the use of lightweight materials such as pumice, perlite, and aerated concrete in buildings.
In this study, it was aimed to solve the waste ash problem emerging from coal, which is used for producing energy in the industry and thermal power plants, as well as producing lightweight building materials by evaluating the utilization efficiency of BA, FA, pumice, and cement.
The acidic pumice used in the study is supplied from Nevsehir province.
The granulometric distribution of the pumice sieved with 8 mm square sieve, IFA, GBA, and BBA sieved with 1 mm square-mesh sieve are given in Figure 1.
Pumice was used as coarse material in the samples consisting of waste ash + pumice mixing.
