Properties of Concrete made with Waste Clay Brick as Sand Incorporating Nano SiO2


The present study aims to investigate the use of clay bricks in concrete preparation. In the first phase of the study, the clay bricks as waste materials from building remains were collected and ground by jaw mills and finally graded in the range of standard sand. The first experiments like XRF, water absorption, and unit weight were then carried out on the materials. After that, some samples with substitution percents of zero to one hundred from waste bricks as sand were made and the new concrete parameters such as compressive strength, water absorption and unit Weight were examined. In the second phase, nano SiO2 in all mixes from the brick waste materials were replaced for the cement and then the experiments of compressive strength and water absorption were done on the samples that contained nano SiO2 and waste clay bricks. The results clearly revealed that, in light of some positive effect such as a reduction in the concrete unit weight and recycling the waste materials and also the minimum reduction of compressive strength, using brick waste materials may be considered a suitable choice in concrete especially in areas close to brick furnaces. Furthermore, nano SiO2 can improve the strength and durability of concrete. Conclusively, using waste bricks can be an effective measure in sustainable development.
