metal soaps introduce some of the main waterproofing agent

Waterproofing agents of metal soaps soluble metal soaps (the soluble soap ) waterproofing agent , and asphaltenes II metal soap waterproofing agent . Water soluble metal soaps agent is stearic acid , ammonia , potassium hydroxide ( or soda) and water heating by  magnesium hydroxide flame retardant mixing a saponified preparation waterproofing agent . This product is a paste -like, mixed with 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 tiny pores and clogging the capillary filling passage effect. Bituminous waterproofing agent is a metal soap liquid petroleum asphalt, lime and water, mixing, grinding is made by drying . Mixed with the PVC foaming board stabilizer  cement mortar and concrete ... a pore size in the nanometer to millimeter . If the surface in contact with the aqueous solution by capillary action will be adsorbed to the surface of concrete and further penetrate into the concrete ; same time , the solution of harmful substances such as chlorine ion , sulfate ion and the like can also be easily transported water into the concrete , reinforced concrete structure to bring serious corrosion damage [ 1 ] . At present , domestic and foreign has  red iron oxide been widely adopted penetration waterproofing agent on the concrete surface water treatment [ 2 ] , but using this traditional approach , the penetration depth of the water repellent is very limited , and in some special cases waterproof effect is not very satisfactory . If you can water repellent mortar or concrete as a component incorporated therein , its protection would be better, this approach is within the mixed water treatment. This paper mainly uses four different types , two kinds of different dosage of metal soap , add it to the concrete mixture to compare , test and research within the mixed metal soap of concrete compressive strength, water absorption coefficient by capillarity and resistance to chloride ion intrusion ability.
