Metal soaps waterproofing agent

Waterproofing agents of metal soaps soluble metal soaps waterproofing agent and a metal soap asphalt waterproofing agent II. Soluble metal soaps
Class waterproofing agent is stearic acid, potassium hydroxide, ammonia and water, by mixing the  tribasic lead sulfate heat saponification preparation, mixed
The cement mortar or concrete, the cement particles and aggregates can form a hydrophobic adsorption layer and between the formation of insoluble matter, from the
Fill tiny pores and clogging the capillary channel effect. Bituminous waterproofing agent is a metal soap liquid petroleum asphalt, stone
Ash and water, mixing, grinding is made by drying, mixed in cement mortar and concrete, mainly from the fill tiny pores and blocking
Cypriot capillary channel effect. Within the mixed metal soaps waterproofing agents for concrete waterproofing and resistance to chloride ion effect study
Concrete is a porous material, a pore size in the nanometer to millimeter. If the surface in contact with the aqueous solution through
Wicking adsorbed to the titanium dioxide  surface of concrete and further penetrate into the concrete; same time, harmful substances in solution,
Such as chloride ions, sulfate ions, it is easy to transport water into the concrete, a reinforced concrete structure serious
Corrosion damage [1]. At present, domestic and foreign has been widely adopted penetration waterproofing agent on the concrete surface water treatment
[2], but using the traditional processing methods, waterproofing agent, the penetration depth is very limited, in some special cases the anti-
Water, the effect is not very satisfactory. If you can mortar or concrete waterproofing agent is used as a component incorporated therein, then the protective
Would be better, this approach is within the mixed water treatment. This paper mainly uses four different types, two kinds of different doping
Amount of metal soap, add it to the pvc additive  concrete mix to compare, test and research within the mixed metal soap of concrete anti-
Compressive strength, water absorption coefficient by capillarity, and anti-invasive ability of chloride ion. Raw materials and the preparation of the specimen
Test the water-cement ratio concrete specimens was 0.5, see the detailed mix. Raw materials used in the experiment are from Qingdao local,
Wherein the maximum particle size of gravel 25mm, sand fineness modulus of
