Exploration of Ultra-Lightweight Aggregate Concrete with Minimal Nano-Si Clay

Abstract

In spite of the fact that Nano modification of cement-based concrete has been praised as a viable technique to increase its mechanical properties, Low-dose Nano alteration of lightweight cement-based concrete has not yet been studied extensively. Low doses of Nano-silica particle-modified light weight cement were studied in this research. “The lightweight concrete samples were made using both non-prewetting and prewetting procedures. Compressive and flexural strengths of lightweight concrete were studied to evaluate how low-dose Nano silica influenced those attributes by the research team.” A novel hydration product has been discovered when it was found that the hydration process may be altered by adding Nano-silica to the cementitious matrix. Using Nano-silica to improve the cement paste's adhesion to lightweight aggregates is now conceivable since new hydration products exist. The novel hydration products' volume expansion at the interface between light aggregates and cement paste is reduced by the presence of large quantities of Nano-silica. Lightweight concrete's mechanical characteristics can be improved using low-dose Nano alteration, and this opens up possibilities for the development and production of new high-performance lightweight concrete products.
