Research on increasing effect of solution polymerization for cement-based composite

Cement-based materials are brittle and low in flexural strength, which can be greatly improved by adding organic monomers to cement-based matrixes due to the polymerization effect of added the organics. The solution polymerization behaviors of organic monomer in cement paste and its effect on cement properties have been studied in this paper. The results show that the organic monomers used in the experiment can well polymerize themselves in cement pastes by solution polymerization effect under common conditions. As results, the cement composites have a flexural strength between 17.8 and 33.4 MPa, greatly dependent on the amount of organic monomers added and is stable when it is immersed in water, acid, alkali and salt solutions. Besides, the setting time of the composites can be controlled and regulated.
