Investigation of the Effect of Microcapsule Additive on Mechanical and Physical Properties of Concrete

Cracks are a fundamental problem in concrete, so this research investigates an experimental study of the effect adding SiO2 on self-healing behaviour concrete. The is done by studying physical properties, microstructure, and mechanical properties Microcapsules were prepared to contain (cement nano SiO2) (palettization (fluidize bed coating) method) with (5,10, 15) % cement weight. ratio concrete mixture was (1: 2: 4) water (W / C) 0.45 weight also added as 0.6% Superplasticizer all mixtures. MC (2.5) mixture. In study, porosity, density, absorption tests performed compressive bending strength properties. So, referring results, (SiO2 MC) used effective cracking mechanism, improving strength. Also, 10 wt. recorded best addition because it has positive be applied construction.
