Embodiment 1
[0037] Thixotropic and self-curing materials are formulated as follows:
[0038] 20% polycarboxylate superplasticizer masterbatch: 12kg;
[0039] Sodium lauryl sulfate: 0.8kg;
[0040] Sodium dodecylbenzenesulfonate: 5kg;
[0041] Xanthan gum: 0.4kg;
[0042] Hydroxyethyl methyl cellulose ether: 1kg;
[0043] Warm rubber: 0.18kg;
[0044] Water: 980.62kg.
[0045] The preparation process is as follows: the xanthan gum, hydroxyethyl methyl cellulose ether and Wenlun gum in the components are first added to the water through sieve analysis and feeding method and stirred to dissolve evenly, and then polycarboxylate superplasticizer is added , Sodium dodecylsulfate and sodium dodecylbenzenesulfonate continue to stir, mixing and stirring for 50 minutes, until they dissolve into a uniform solution without agglomeration.
[0046] The slip form construction process is as follows:
[0047] (1) The C40 concrete mix ratio for the 1.18-meter-high anti-collision barrier is as follow...
Embodiment 2
[0063] Thixotropic and self-curing materials are formulated as follows:
[0064] 40% polycarboxylate superplasticizer masterbatch: 5kg;
[0065] Sodium lauryl sulfate: 0.5kg;
[0066] Sodium dodecylbenzenesulfonate: 3kg;
[0067] Xanthan gum: 0.2kg;
[0068] Hydroxypropyl methylcellulose ether: 0.7kg;
[0069] Modified starch ether: 0.05kg;
[0070] Water: 990.55kg.
[0071]The preparation process is as follows: the xanthan gum, hydroxypropyl methyl cellulose ether and modified starch ether in the components are first added into water by sieve analysis and feeding method, stirred to make them uniformly dissolved, and then polycarboxylate water-reducing The agent, sodium dodecylsulfate and sodium dodecylbenzenesulfonate continue to stir for 40 minutes until they dissolve into a uniform solution without agglomerates.
[0072] The slip form construction process is as follows:
[0073] (1) The C35 concrete mix ratio of 0.5m high drainage ditch is as follows:
[0074] P.O42...
