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