After 6.55%, resistance to compression, flexural strength are improved, but the slump is 0, is unable to moulding by casting.It is with water ratio and silicon ash ratio
Governing factor, as long as in the reasonable scope with water and the control of silicon ash ratio, UHPC performance is met the requirements.
As shown in Figs 1-4, the track plates of the anti-stray current include track plates main body 4, and 4 upper surface of track plates main body is set
Two column tracks 2 are set, the injected hole 3 of penetrating orbit plate, the track plates are set between two column tracks 2 in track plates main body 4
Track plates bottom 7 is arranged in the lower part of main body 4, sets FRP tendons net, entire track plates external coating emulsified asphalt in track plates main body 4
Coating 1；The material of the track plates main body 4 is phosphor aluminate cement base UHPC, and the material of the track plates bottom 7 is phosphorus aluminic acid
Salt cement base UHPC adds 30% emulsified asphalt.
The FRP tendons net includes FRP transverse bar 5, the vertical muscle 6 of FRP and FRP supporting rib 8；
The FRP transverse bar 5 and FRP indulge 6 interlaced arrangement of muscle and form one layer of FRP tendons net, and the FRP tendons net includes upper and lower two
Layer FRP tendons net, upper and lower two layers of FRP tendons Netcom crosses FRP supporting rib 8 and is connected as one, the FRP transverse bar 5 of upper and lower two layers of FRP tendons net
6 point of intersection of muscle is indulged with FRP and FRP supporting rib 8 ties up fixation by plastic ties.
When prepared by track plates, it will first be assembled with the mold that track 2 constructs, in the default prefabricated PVC in slip casting hole site
FRP transverse bar 5 and FRP are indulged muscle 6 and the plastic ties 9 of FRP supporting rib 8 are bundled into FRP tendons net, FRP tendons net is put into mold by pipe,
Successively be poured into mold by the UHPC mixture prepared and mixed with the UHPC mixture of 30% emulsified asphalt, in mold from down toward
On sequentially form track 2, track plates main body 4 and track plates bottom 7, pull out pvc pipe, pvc pipe after UHPC mixture final set
Position formed injected hole 3.After standing 1 day, demoulding, track plates external coating emulsified asphalt coating steams track plates with 90 DEG C
Vapour conserves 48 hours or natural environment conserves one week.
