Special Issue Information

Dear Colleagues,

The development of polymer–cement composites provides multi-functionalized materials necessary to optimize the use of cement composites in practical engineering. Various polymers have been developed to modify the properties of cement and enhance the performance of cement composites. The synthesis, properties and applications of polymers, as well as polymer–cement composites are popular topics in the area of construction materials. In recent years, extensive studies have been carried out to explore new polymers to improve the performance of cement composites. The effects of these polymers on the properties of cement composites have been investigated and revealed, and the results  demonstrate promising applications of the new composites. In this regard, this Special Issue, entitled “Polymer–Cement Composites: Synthesis, Properties and Applications”,  aims to collect and summarize novel ideas, results and reviews on polymer–cement composites. This list is only indicative and by no means exhaustive; any original theoretical or simulation studies or review articles on the role of polymer–cement composites are welcome.

The integrity of oil well cement sheaths is closely related to the long-term production safety of oil and gas wells. The primary material used to form a cement sheath is brittle. In order to reduce the brittleness of oil well cement and improve its flexibility and resistance to stress damage, nano-silica was used to modify polymer elastic particles, and their properties were analyzed. The influence of the modified polymer particles on the properties of oil well cement-based composite materials was studied, and the microstructure of the polymer particle cement sample was analyzed. The results showed that nano-silica effectively encapsulates polymer particles, improves their hydrophilicity, and achieves a maximum temperature resistance of 415 °C. The effect of the modified polymer particles on the compressive strength of cement sample is reduced. Polymer particles with different dosages can effectively reduce the elastic modulus of cement paste, improve the deformation and elasticity of cement paste, and enhance the toughness of cement paste. Microstructural analysis showed that the polymer particles are embedded in the hydration products, which is the main reason for the improvement in the elasticity of cement paste. At the same time, polymer particle cement slurry can ensure the integrity of the cement sample after it is impacted, which helps to improve the ability of oil well cement-based composite materials to resist stress damage underground.
