Abstract
The invention discloses a concrete waterproofing agent. The concrete waterproofing agent is prepared from the following constituents in parts by weight: 10-20 parts of aluminum slag, 15-25 parts of iron-ore slag, 5-15 parts of silica fume, 1-5 parts of white alum, 1-5 parts of calcium chloride, 1-5 parts of sodium nitrite, 2-8 parts of aluminum potassium sulfate, 0.5-3 parts of alkyl sodium sulfonate, 1-5 parts of calcium phosphate, 1-5 parts of stearic acid, and 0.1-1 part of triethanolamine. The concrete waterproofing agent provided by the invention is simple in formula, good in adaptability to cement, stable in quality, low in cost, good in acid-base resistance and waterproofing crack resistance, high in anti-permeability strength, and good in ageing-resistant performance.
Description
Technical field
The present invention relates to a kind of concrete external additive, be specifically related to a kind of concrete waterproofer.
Background technology
In concrete construction, after concrete coagulation sclerosis, be easy to produce cracking phenomena owing to producing by reinforced binding effect, had a strong impact on concrete weather resistance.For this reason, people add all kinds of external additive usually to improve concrete resistance to cleavage in concrete.Concrete waterproofer is exactly one wherein, and it plays shrinkage-compensating effect in cement concrete, prevent concrete cracking.The exploitation trend of current concrete waterproofer is, utilize all types of industries waste residue 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 concrete waterproofer simple, water-proofing anticracking performance is good 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 concrete waterproofer, be made up of the component of following weight part:
Aluminium ore slag 10 ~ 20 parts, Iron-ore Slag 15 ~ 25 parts, silicon ash 5 ~ 15 parts, 1 ~ 5 part, alum, 1 ~ 5 part, calcium chloride, Sodium Nitrite 1 ~ 5 part, potassium aluminium sulfate 2 ~ 8 parts, alkyl sodium sulfonate 0.5 ~ 3 part, 1 ~ 5 part, calcium phosphate, stearic acid 1 ~ 5 part, trolamine 0.1 ~ 1 part.
