The results of researching mechanical properties of quick hardening modified concrete materials
Incoming article date: 16.12.2016The results of researching the speed of increasing strength of modified concrete materials in early period of hardening used for mounting underground structures are given. As a result of researching the most effective supplements like D5 and RELAMIX T-2 are determined. The composition of supplement D5 with fillers of ordinary quality and a con drafting 15 sm, it will gain high strength of 6.5 MРa in 18 hours while with RELAMIX T-2 fillers it will be 2.8 MРa. The given results were used for modeling stress strained state of ground mass and concrete fastenings of non- circular shape.
