Concrete anticorrosive and rust-inhibiting pumping agent

Abstract

The invention relates to a concrete anticorrosive and rust-inhibiting pumping agent which is compounded by using a water-reducing component, a slump-retaining component, a rust-inhibiting component, an expansion component, an air-entraining component, and a defoaming component. The pumping agent satisfies various performance specifications of three national industry standards which are JC473-2001 concrete pumping agent, JC / T1011-2006 of concrete sulfate-erosion-resistant preservative, and JT / T537-2004 reinforced concrete rust inhibitor. With one time of dosing, concrete corrosion prevention, reinforcement rust inhibition, and pumping construction requirements can be satisfied.

Description

technical field [0001] The invention belongs to a concrete anti-corrosion and anti-rust pumping agent. Background technique [0002] Concrete pumping agent is an admixture that can improve the pumping performance of concrete mixture, so that the concrete mixture can pass through the pipeline smoothly, without blocking, without segregation, and with good viscoplasticity. It is usually composed of water reducing agent , retarder and other compounds. With the continuous development of concrete construction engineering technology, higher requirements are put forward for the performance of concrete, especially the durability indicators of concrete such as anti-corrosion and anti-corrosion of steel bars are more prominent. At present, in order to meet the common needs of concrete performance and construction, the usual method is to add one or two functional admixtures and pumping agents to the concrete to form a mixture, which not only increases the difficulty of construction and...

Problems solved by technology

At present, in order to meet the common needs of concrete performance and construction, the usual method is to add one or two functional admixtures and pumping agents to the concrete to form a mixture, which not only increases the difficulty of construction and production costs , and it is very easy to repeatedly add the same or similar components in several concrete admixtures, resulting in excessive or missing additions, etc., especially when encountering several concrete admixtures with poor or even incompatible compatibility When the admixture is added, it will reduce the effectiveness of the admixture, and the light result will cause concrete water leakage, segregation, hardening, reduce until the loss of working performance, so that it cannot be pumped, and the severe one will cause construction safety accidents and serious concrete quality accidents, thus endangering Building Safety Life
