Embodiment 1

[0011] Example 1: Take the construction of a bearing column for a large-scale workshop of a factory building as an example

[0012] Concrete composite agent, composed of the following raw materials in weight percentage: 50% silicon dioxide, 35% fluorspar, 5.5% sodium cetylbenzenesulfonate, 8.7% hydroxycarboxylic acid, aliphatic hydroxysulfonate high-efficiency water reducer 0.8%. Firstly, silicon dioxide, fluorspar, and sodium cetylbenzenesulfonate are firstly ground by Raymond Mill respectively, mixed in proportion and then secondly ground by ball mill, and the obtained powdery mixture is passed through a standard with a fineness of 400 mesh. Sieve, then add hydroxycarboxylic acid and aliphatic hydroxysulfonate high-efficiency water reducer to the above powder mixture, stir evenly, pass through a standard sieve with a fineness of 400 mesh, and the sieve residue is less than 5% to be the finished product.

Abstract

The invention discloses a concrete complexing agent as additive in the architectural material technical domain, which comprises the following parts: 48-55% silica, 27.5-45% fluorite, 2.5-8% sodium cetylsulfate, 4-9% hydroxy carboxyl acid and 0.5-1% aliphatic hydroxy sulfonate high-effective dehydragent. The complexing agent improves particle bond of concrete aggregate, which saves cement quantity by 10-20%.

Description

technical field [0001] The invention relates to an additive in the technical field of building materials, in particular to a concrete compounding agent. Background technique [0002] Known concrete components such as concrete railway sleepers, concrete bridge decks, bridges, expressway cushions, etc. are all rigid structures. At present, the evaluation of known concrete components pays more attention to their compressive strength. However, the compressive grades of existing domestic concrete components are generally C30-C50, and foreign countries are C50-C70. The surface of components is prone to cracks and damage. The main reason is After the concrete is solidified, the void ratio in it is relatively high, and the particle holding force is poor. In this way, under the (frequent) instantaneous heavy pressure or impact force of the concrete member, the (frequent) ultimate load of the concrete member will cause the surface of the member to appear tortoise. Cracks and damages ...
