“…These particles, without suffering many Coulomb scattering, is a good measure of the hadrons produced in the last few generations. It's a useful parameter sensitive to the identity of the primary particle, because the number of hadrons in a shower reduces with the elongation of the shower quite sensitively [3].…”

“…By this "inserting action", telechlic polymer enhances the binding force between C-S-H gels, so as to realize the In-situ toughening. This concept enlightened Ding Bei [2,3] to successfully improve the toughness of concrete significantly with relatively small amount of a type of telechlic polymer through polymer design and functional groups selection. Further study revealed that this type of telechlic polymer did increase the average chain length of silicon oxygen tetrahedron in C-S-H gel, but did not insert into its layer structure, which violated the original In-situ toughening Concept.…”

To find out the toughening mechanism of in-situ toughening telechelic polymers (ITTP) in concrete, SEM & EDS and Nano indenter were used to research the variation of concrete hydration products and the interfacial transition zone between the cement paste and aggregate. The results indicate that the toughening effect of ITTP is not carried out by film formation. And the proportion of LD C-S-H in cement hydration products increased significantly and the CH content decreased after introducing the ITTP into concrete. Nano indentation test results show that the non-dense area ratio of ITZ decreased, and the CH content in ITZ increased slightly. The Ca/Si blurred from mutation pattern with decreasing the distance to aggregate surface in the region of interfacial transition zone between aggregate and cement paste, and the thickness of ITZ increased. The conclusions show that the ITZ and hydration products are both key micro-structures which affect the toughness of concrete, and it provides us some guidance for realizing concrete toughness ascension through microstructure adjustment.
