firstly, sintering to obtain the glass pumice, wherein the step is similar to the sintering mode of the conventional glass pumice;
the glass pumice mainly comprises the following components in percentage by weight: glass powder: 90-95, marble powder: 2-5, alumina powder: 1-3, calcite powder: 1-3; wherein the fineness of the glass powder is 40-100 μm, the fineness of the marble powder is 20-40 μm, and the fineness of the alumina powder is 20-40 μm; the fineness of the calcite powder is 20-40 mu m.
The glass pumice obtained under different mixture ratio combinations can have the following performance relationship:
serial number Monomer Dry Density (g/cm)2 Monomer mass water retention (%) Compressive strength of monomer (MPa) Barrel pressure intensity (MPa)
1 0.2~0.4 ≥40 0.9~1.5 ≥0.08
2 0.3~0.5 30~40 2.5~3.0 ≥0.25
