Study on Modification Mechanism of the Polymer Modified Cement Concrete

摘要

The Modification mechanism of the Polymer Modified Cement Concrete was studied by the DTA, SEM and MIP with the confirmation of lab test results. The research indicated: the more dosage of the polymer, the less content of the Ca(OH)2 in the Cement hydrated product. The pore structure was improved evidently simultaneously. The polymer film tend to more complete and interweaved with Hydration products. Therefore the netted structure was formed and the flexiblity of concrete was increase greatly. Lab test results also proved it: when continued adding the polymer, the performance of concrete improved remarkably.
