Problems solved by technology

The initial setting time of concrete needs to be adjusted according to the actual construction conditions. For example, when the construction of occlusal piles is too long, the initial setting time of concrete is generally required to be about 60 hours, while the initial setting time of general concrete is 6- About 8 hours, so ordinary concrete cannot adapt to this construction condition

Embodiment 1

[0032] The invention discloses a super retarded concrete, which comprises the following raw materials in parts by weight:

[0033]

[0034]

[0035] Wherein, super retarder comprises the following components by weight percentage:

[0036]

[0037] The emulsifier in the super retarder is OP-40 emulsifier.

[0038] In terms of weight percentage, the reinforcing agent raw materials include 30% polypropylene fiber, 30% steel fiber, 5% rolling aid, 5% self-repairing microcapsule, 2% dispersant, and 28% water, wherein the rolling aid includes silane coupling Agent 30%, OP-40 emulsifier 10%, epoxy resin 5%, butyl acetate 55%. The core material of the self-healing microcapsule is epoxy resin core material; the wall material is urea-formaldehyde resin.

[0039] The reinforcing agent production steps are as follows: knead the polypropylene fiber and the steel fiber by using a texturing machine, and spray the mixed solution of kneading aid, self-repairing microcapsule, dispers...

Abstract

The invention discloses super retarded concrete, and relates to the technical field of concrete, and the super retarded concrete comprises the following raw materials in parts by weight: 280-380 partsof cement, 80-100 parts of mineral powder, 100-125 parts of fly ash, 1100-1600 parts of natural macadam, 600-700 parts of yellow sand, 3-8 parts of an ultra-retarding agent and 180-200 parts of water. The preparation method has the advantages that the initial setting time of the concrete is prolonged, and the strength of the concrete is improved.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a super retarded concrete. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. [0003] Existing concrete is usually poured and formed by mixing and stirring aggregates, cementitious materials and various additives. The initial setting time of concrete needs to be adjusted according to the actual construction conditions. For example, when the construction of occlusal piles is too long, the initial setting time of concrete is generally required to be about 60 hours, while the initial setting time of general concrete is 6- About 8 hours, so ordinary concrete cannot adapt to the construction conditions. Contents of the invention [0004] In view of ...
