Abstract
The invention provides a concrete waterproof agent. The concrete waterproof agent is prepared from the following raw materials in parts by weight: 30-50 parts of straw powder, 5-10 parts of silicon powder, 4-6 parts of alum, 4-7 parts of rosin soap, 2-6 parts of potassium dichromate, 5-8 parts of gelatin, 0.5-1.2 parts of sodium chloride, 10-15 parts of stearic acid, 12-16 parts of dimethyl siloxane, and 5-10 parts of polyvinyl alcohol. The waterproof agent disclosed by the invention is good in adaptability to concrete, good in stability, light in weight and low in cost, has favorable waterproof crack resistance and ageing resistance, and is good in impermeability intensity.
Description
Technical field
The present invention relates to a kind of waterproofing agent, be specifically related to a kind of waterproofing agent for concrete.
Background technology
In concrete construction, after concrete coagulation hardening, it is easy to produce cracking phenomena owing to being produced by reinforced binding effect, has had a strong impact on the durability of concrete, to this end, people generally add all kinds of external additive to improve the cracking resistance of concrete in concrete.Concrete waterproofer is exactly one therein, and it, in cement concrete, plays shrinkage-compensating effect, prevent concrete cracking.At present, the problem that the waterproofing agent of concrete the most often exists poor effect it is commercially for.
Summary of the invention
The technical problem to be solved is to provide a kind of concrete waterproofer.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of concrete waterproofer, it is made up of the raw material of following weight portion:
Powder of straw 30-50 part；
SILICA FUME 5-10 part；
Alumen 4-6 part；
Rosin soap 4-7 part；
Potassium dichromate 2-6 part；
Gelatin 5-8 part；
Sodium chloride 0.5-1.2 part；
Stearic acid 10-15 part；
Dimethyl siloxane 12-16 part；
Polyvinyl alcohol 5-10 part.
The particle diameter of described powder of straw is 15-22 μm.
The invention has the beneficial effects as follows: the waterproofing agent of the present invention is good to concrete adaptability, good stability, light weight, cost is relatively low, has good water-proofing anticracking performance and ageing-resistant performance, and anti-permeability strength is high.
Detailed description of the invention:
Below in conjunction with embodiment, the present invention is described in further details.
