Embodiment 1
[0035] refer to figure 1 , a concrete application process with antirust function, comprising the steps of:
[0036] S1: Build the pouring formwork. According to the design drawings, build the pouring formwork for the concrete components.
[0037] S2: Reinforcement pretreatment. Clean the steel bars with clean water first, and then use oxalic acid to clean the steel bars a second time. Then, 25 parts by weight of dodecenyl succinic acid and 25 parts of sodium petroleum sulfonate are painted on the surface of the steel bar, and then 30 parts by weight of water-based acrylic polyurethane are painted on the steel bar. Finally, 15 parts by weight of triethanolamine dodecylbenzenesulfonate was coated on the steel bar, and then S3 was performed.
[0038] S3: Pre-embedded reinforcement. According to the design drawings, the steel bars after S2 treatment are pre-embedded, bound and fixed in the pouring formwork.
[0039] S4: Prepare concrete. At room temperature, 379 parts by we...
Embodiment 2
[0043] An application process of concrete with antirust function, comprising the steps of:
[0044] S1: Build the pouring formwork. According to the design drawings, build the pouring formwork for the concrete components.
[0045] S2: Reinforcement pretreatment. Clean the steel bars with clean water first, and then use oxalic acid to clean the steel bars a second time. Then, 20 parts by weight of dodecenyl succinic acid and 20 parts of sodium petroleum sulfonate are painted on the surface of the steel bar, and then 20 parts by weight of water-based acrylic polyurethane are painted on the steel bar. Finally, 10 parts by weight of triethanolamine dodecylbenzenesulfonate was coated on the steel bar, and then S3 was performed.
[0046] S3: Pre-embedded reinforcement. According to the design drawings, the steel bars after S2 treatment are pre-embedded, bound and fixed in the pouring formwork.
[0047] S4: Prepare concrete. At room temperature, 325 parts by weight of Portland ...
Embodiment 3
[0051] An application process of concrete with antirust function, comprising the steps of:
[0052] S1: Build the pouring formwork. According to the design drawings, build the pouring formwork for the concrete components.
[0053] S2: Reinforcement pretreatment. Clean the steel bars with clean water first, and then use oxalic acid to clean the steel bars a second time. Then, 30 parts by weight of dodecenyl succinic acid and 30 parts of sodium petroleum sulfonate are painted on the surface of the steel bar, and then 40 parts by weight of water-based acrylic polyurethane are painted on the steel bar. Finally, 20 parts by weight of triethanolamine dodecylbenzenesulfonate was coated on the steel bar, and then S3 was performed.
[0054] S3: Pre-embedded reinforcement. According to the design drawings, the steel bars after S2 treatment are pre-embedded, bound and fixed in the pouring formwork.
[0055] S4: Prepare concrete. At room temperature, first add 432 parts of Portland ...
