Dispersion performance of carbon nanotubes on ultra-light foamed concrete

Abstract

This study investigates the effect of carbon nanotube (CNT) dispersion on the mechanical properties and microstructures of ultra-light foamed concrete. A type of uniform and stable CNT dispersion solution is obtained by adding nano-Ce(SO4)2. Results show that CNT dispersion increases the compressive and breaking strengths of foamed concrete. CNTs play a nuclear role in the crystallization of C-S-H, and CNT dispersion effectively promotes the grain growth of C-S-H. The effect of CNT dispersion on the compressive and breaking strengths of foamed concrete is predicted through simulation.
