Compressive strength measurement

the compressive strengths of SH-H-7, SS-H-7, SH-HV-7 and SS-HV-7 are 13.2 MPa, 18.96 MPa, 8.93 MPa and 29.81 MPa, respectively.

the compressive strength of the specimens with respect to compaction pressure. Compaction pressures of 0, 2.5, 5.0, and 7.5 MPa yielded compressive strengths of 20.8, 46.3, 53.5, and 56.2 MPa,

The results showed that the 28-day compressive strength of the BH-1 geopolymer was improved by up to 100.8%.

The primary aim of this study is to understand how changes in composition affect the material properties of geopolymers formed from BP-1 lunar regolith simulant under a standardized curing protocol.

Engineering stress strain curves for 6 samples of BP-1 geopolymer created with 70 wt% BP-1, an activating solution of nominal molar ratio 0.3Si/, and an activating solution of 60 wt% water.
