Abstract
The invention discloses a concrete expanding agent. The concrete expanding agent comprises, by weight, 30 parts of fly ash, 5 parts of fluorogypsum powder, 3 parts of mekralon, 15 parts of calcium carbonate powder, 1.8 parts of high-aluminum clinker and 11.6 parts of aluminum slag. The concrete expanding agent has a simple formula and good cement adaptability, utilizes industrial waste residue as a raw material, and has a low cost, a low doping amount, low alkali content, high compressive strength, a high expansion ratio, good expansion stability and outstanding economic benefits, environmental protection benefits and social benefits.
Description
Technical field
The present invention relates to a kind of concrete external additive, be specifically related to a kind of cement expansive material.
Background technology
Swelling agent is a kind of concrete external additive, is added in cement and makes concrete, and when cement setting hardens, volumetric expansion thereupon, plays compensate for shrinkage and tension reinforcing steel bar produces prestress and filling concrete gap.The exploitation trend of current cement expansive material is, utilize all types of industries waste residue, such as aluminum oxide clinker, and use for reference production and the utilisation technology of other concrete admixture, the blended material class raw material and admixture component with dedicated functions is mixed when preparing swelling agent, while reducing to make cost, obtain the product of superior performance.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cement expansive material simple, rate of expansion is high of filling a prescription.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A kind of cement expansive material, be made up of the component of following weight part:
20 ~ 30 parts, flyash, fluorine gypsum powder 5 ~ 15 parts, polypropylene fibre 1 ~ 5 part, Paris white 5 ~ 15 parts, high alumina 1 ~ 10 part, aluminium ore slag 10 ~ 20 parts.
As one of preferred, the weight part of described component is:
20 parts, flyash, fluorine gypsum powder 11.5 parts, polypropylene fibre 5 parts, Paris white 5 parts, high alumina 8.8 parts, aluminium ore slag 20 parts.
As one of preferred, the weight part of described component is:
24 parts, flyash, fluorine gypsum powder 15 parts, polypropylene fibre 1 part, Paris white 12 parts, high alumina 9.5 parts, aluminium ore slag 10 parts.
As one of preferred, the weight part of described component is:
30 parts, flyash, fluorine gypsum powder 5 parts, polypropylene fibre 3 parts, Paris white 15 parts, high alumina 1.8 parts, aluminium ore slag 11.6 parts.
The invention has the beneficial effects as follows:
Cement expansive material provided by the invention is owing to adopting new formula, it is good to cement adaptability, product with all types of industries waste residues such as aluminum oxide clinker, aluminium ore slag for raw material obtain, cost is low, and its volume is low, and alkali content is low, ultimate compression strength is high, rate of expansion is high, expansion good stability, has outstanding economic benefit, environmental benefit and social benefit.
