Project Background:
Concrete's low toughness and flexural strength, coupled with high brittleness, lead to cracking that accelerates deterioration and reduces load capacity, impacting structural safety. Modern construction demands materials with better crack and toughness resistance. While polymers improve toughness, issues with dispersion and bonding within cementitious materials limit performance gains, and enhancing these properties remains a challenge.
Aims & Goals:
1. To develop a cement-based composite material with enhanced flexural strength;
2. To foster organic-inorganic bonding between monomers/polymers and cement;
3. To clarify the mechanism by which in-situ monomer polymerization modifies the performance and microstructure of cement-based materials.
4. To promote the application of oil-based monomers of acrylates in civil engineering materials.
