Abstract: In order to study the influence of carbobutadiene latex on the properties of concrete, this study studied the influence of carbobutadiene latex content on the microstructure of modified concrete. First of all, material selection and production of specimens, and then the physical properties, mechanical properties and microstructure of specimens were analysed to complete the effect of carboxybutene styrene latex content on the microstructure of modified concrete. The experimental results show that the modified concrete has better performance, minimum water reduction rate and higher bulk density when the content of carboxybutene styrene emulsion is 15%. By observing the microstructure, it is found that there are tree-trunk structure, latex film structure and interpenetrating network structure between latex film and concrete hydration products. At the same time, there are conical particles, which can greatly improve the performance of concrete.

Keywords: carboxybutylbenzene; lotion content; modified concrete; microstructure.
