Tension and compression strength evaluation method for LSAM-50 high-temperature performance

The invention discloses a lamp with LSAM-50 high-temperature performance and a preparation method of the lamp. The compressive strength evaluation method comprises the following steps: preparing a cylindrical test piece with a specific size; placing the cylindrical test piece in a T DEG C environment box, and preserving heat for 6-8 hours; taking out the heat-preserved test piece, and testing the compressive strength R and the splitting strength r of the cylindrical test piece; according to the compressive strength R and the splitting strength r of the LSAM-50, the cohesive force a and the internal friction angle gamma are calculated according to a formula; the LSAM-50 lamp is calculated according to a formula; the pressure strength is mu; the method comprises the following steps: preparing an LSAM-50 cylinder test piece, preserving the temperature of the test piece to a specific temperature, testing the compressive strength R and the splitting strength r of the cylinder test piece according to Test Regulatio
