| Résumé : |
This paper mainly explores the strength and performance of rice straw ash cernent mortar. Firstly, the straw ash was obtained through high-temperature calcination, and the ash formation rate was measured. Then, the straw ash was rinsed with clean water and mixed into cernent mortar test pieces. According to the mass ratio of cernent in the test pieces, the proportion of straw ash were determined as 5 %, 10 %, 15 % and 20 %, respectively. Next, the following properties of each test piece were measured, including water absorption rate, 3d and 28d flexural strength and compressive strength. On this basis, the flexural strength and compressive strength were fitted and correlated with the proportion of straw ash. The fitting formulas and correlation functions proposed in this paper lay a theoretical basis for the engineering application of straw ash cernent mortar. |
