Problems solved by technology

[0003] The existing concrete aging technology uses chemical substances such as acid to corrode the concrete surface, so as to achieve the effect of aging, but the effect is not ideal, because the concrete material is hard, high density, not easy to corrode, and the traditional treatment technology is difficult If it is uniformly corroded, the effect is difficult to meet the requirements and the cost is high
The economy and environmental protection are also relatively poor, and the environmental pollution is serious

Embodiment 1

[0027] Prepare 30 pieces of 400mm*400mm*60mm rigid molds for mold cleaning and assembly; reconcile the aging treatment solution A with water at a mass ratio of 1:4, and spray the prepared aging treatment solution A evenly on the 400mm*400mm rigid mold surface Above: Pour fresh concrete into the mold coated with aging treatment solution A, let it stand for curing for 24 hours and then release the mold; rinse the 400mm*400mm concrete surface in contact with aging treatment solution A with clean water, and wash off the uncured concrete Ingredients, let it stand to dry for 3 hours; mix the aging treatment solution B with water at a mass ratio of 1:1, spray it on the dried 400mm*400mm concrete surface, and let it stand for 3 hours after spraying to make the aging treatment solution B fully penetrates into the pores of the concrete surface to form a protective layer, and the aging process ends.

Abstract

The invention discloses a concrete antiquing method which mainly comprises the following four steps: step 1, before pouring concrete, assembling a mold, and spraying a layer of concrete antiquing treatment liquid A on the inner surface of the mold; step 2, pouring concrete into the mold, and curing and demolding; step 3, washing the surface of the demolded concrete with clear water; and step 4, spraying an antiquing treatment liquid B after the water on the surface of the concrete is evaporated. According to the method, the antiquing effect is directly achieved after concrete demolding throughearlier-stage treatment, convenience and environmental protection are achieved, and the durability of concrete is not greatly affected.

Description

technical field [0001] The invention relates to a method for making old concrete, in particular to a method for making old prefabricated concrete in a factory. Background technique [0002] Concrete aging is a special process in the renovation of the old urban area. It is mainly to process brand-new concrete products to form a seemingly decades-old baptism, which can give people a sense of vicissitudes and depth. The precipitation of the years is consistent with the visual impact of the old city and ancient buildings, and is coordinated with the entire area. [0003] The existing concrete aging technology uses chemical substances such as acid to corrode the concrete surface, so as to achieve the effect of aging, but the effect is not ideal, because the concrete material is hard, high density, not easy to corrode, and the traditional treatment technology is difficult If it is uniformly corroded, the effect is difficult to meet the requirements, and the cost is high.
