ABSTRACK
The research objective was to determine the properties of physical and mechanics of mouse
purun cement board on various hardeners. The cement board was processed with a size of 30 cm
x 30 cm x 2 cm, a ratio of 3: 1, a density of 2 g / cm2
, purified water content of 15%, hardener
Ca(OH)2, CaCl2, MgCl2 with a concentration of 2%. Before making the cement board the
hydration temperature test is carried out, then the resulting board is tested for the physical
properties of the mechanics. And the grave test for 3 months. Data averaged and SD then
tabulated and written in graphical form. The results of the study were hydration temperature:
31.38-33.50oC, inhibiting factors: 6.94-10.19%, board water content: 13.55% - 15.77%; density:
1.07-1.16 g / cm2; MoR: 22.96 - 30.31 kg / cm2, Compressive strength: 0.84 - 3.34%.
Conclusion: Mouse purun can be processed into cement board. The good nature of the cement
board is to treat CaCl2 2% hardener.
Keywords: Purun, cement board, hardener, hydration and MoR
