Abstract
The invention discloses a concrete modifying agent. The concrete modifying agent comprises the following components in percent by weight: 20%-30% of bentonite, 5%-10% of acrylic emulsion, 5%-10% of polypropylene fiber and the balance of nano carbon powder. The concrete modifying agent prepared in the invention is small in adulterate amount and good in conductivity, and does not affect strength of the concrete.
Description
Technical field
The present invention relates to a kind of concrete modifying agent, be specifically related to a kind of concrete modifying agent with conductivity.
Background technology
Concrete, because its good physical and mechanical property is widely applied in field of civil engineering, is a kind of material of construction of current usage quantity maximum.The resistivity of normal concrete is high, belongs to electric poor conductor.In normal concrete, add the electro-conductive material of certain content, can make its conductivity greatly improve.The feature of conducting concrete existing structure material, there is again electroconductibility and alert and resourceful characteristic, this just makes concrete not only as a kind of structured material, use, and at electrician, electromagnetic interference shield, industrial electrostatic prevention, electric heater, power equipment earth work, and the aspect such as the internal stress of great Civil Infrastructure Systems and healthy state self diagnosis and monitoring has vital role.
Wherein, conductive component, as disperse phase, adopts carbon fiber, graphite, steel fiber etc. more.Graphite is a kind of inorganic materials easily obtaining, and it not only has good electroconductibility, thermal conductivity, and has good unreactiveness, but its volume is high, can make concrete intensity significantly reduce.
Summary of the invention
To the object of the invention is the defect existing in prior art in order solving, a kind of properties-correcting agent that has excellent conductive performance and do not affect concrete strength to be provided.
In order to achieve the above object, the invention provides a kind of concrete modifying agent, comprise the component of following weight percentage:
Wilkinite 20%-30%,
ACRYLIC EMULSION 5%-10%,
Polypropylene fibre 5%-10%,
All the other are nano-carbon powder.
Wherein, the preferred sodium bentonite of wilkinite.
The screening formulation of concrete modifying agent of the present invention is:
Nano-carbon powder 60%,
Sodium bentonite 25%,
ACRYLIC EMULSION 7%,
Polypropylene fibre 8%.
The present invention has the following advantages compared to existing technology: the conductivity that utilizes nano-carbon powder, by adding wilkinite to make product there is good plasticity-and cohesiveness, utilize nano-carbon powder and wilkinite composite as suspension agent simultaneously, increase the stability of product, reduce the consumption of nano-carbon powder simultaneously.The present invention utilizes ACRYLIC EMULSION to improve the impermeability of product, utilizes polypropylene fibre in concrete, to form the netted support effect of three-dimensional random distribution, effectively improves concrete intensity, improves concrete anti-crack and anti-seepage performance.The concrete modifying agent volume little (add-on is only the 3%-5% of concrete quality) that the present invention prepares, the incorporating modified dose of concrete preparing resistivity under drying conditions is less than 1.47 Ω m, folding strength is greater than 9.1MPa, and ultimate compression strength is greater than 45.3MPa.
