ABSTRACT

Because of the characteristics of the materials and the limitations of the use environment, the durability of cement-based materials is insufficient. The freeze-thaw damage of cement-based materials is the most serious in the south. Based on the above background, the main purpose of this paper is to study the frost resistance of nano and PVA modified fiber cement-based composites. In this research, varied amounts of PVA fiber and nano particle are mixed with a fixed amount of water, superplasticizer, and sand in a cement-based composite. Then, using the quick freezing method, the relative dynamic elastic modulus of each sample is determined. The frost resistance of single PVA fiber and nano PVA fiber cement-based composites is examined, and the influence of nano-SiO2 and PVA fiber on cement-based composites is investigated. Frozen resistance has an impact. The findings of the experiments suggest that adding PVA fiber to cement-based composites improves their frost resistance significantly. With the addition of nano silica to PVA fiber cement-based composites, the frost resistance of PVA fiber cement-based composites is increased. When nano silica content is high, when the content of nano silica is 2.5% and PVA fiber is 0.4%, the frost resistance of cement-based composite is the best.
