Research on the properties of rubber concrete containing surface-modified rubber powders
Original language description
Through the comparison of several modified rubber powders and their corresponding rubber concrete, the influence of rubber surface modification on the properties of rubber concrete and the engineering practicability of rubber concrete prepared by different rubber modification methods are understood. The surface changes of rubber modified by sodium hydroxide, sulfonation and urea were studied by contact angle and infrared spectroscopy. The basic mechanical properties and impact resistance of modified rubber concrete were studied by SEM and software image analysis. The results show that the rubber modification can improve the interaction between cement paste and rubber and improve the adhesion between them. Compared with ordinary rubber concrete, the compressive strength of rubber concrete treated with sodium hydroxide is only slightly improved, but its flexural strength,tensile splitting strength and impact resistance are greatly improved. After the rubber is modified by urea or sulfonation, a variety of polar groups are introduced on the rubber surface, which increases the mutual attraction between rubber particles and cement paste, improves the compressive strength, tensile splitting strength, flexural strength and impact resistance of rubber concrete, and greatly reduces the strength loss of rubber concrete. Rubber modification improves the performance of rubber concrete, showing good application potential.
