Embodiment Construction
[0009] C30 column, 2.8 meters high, using ordinary concrete formwork and adding concrete surface anti-carbonation formwork for comparison, the admixture is added 40%, and the slump is 210mm. After pouring, the ordinary mold is well sealed and there is no water seepage. Increase the anti-carbonation formwork of the concrete surface, the surface has good water permeability, and no concrete slurry is secreted. The purpose of reducing the water consumption of concrete is achieved without affecting the appearance and shape of concrete.
[0010] After 28 days of outdoor testing, the carbonation depth of the concrete formed by ordinary formwork is 6.2mm. Increase the carbonation depth of the concrete formed by the anti-carbonation formwork on the concrete surface to 1.7mm to achieve the purpose of improving the carbonation resistance of the concrete.
