Abstract: inorganic salts are important admixtures usually used in cold weather concrete. as research basic of influence of salts on concrete durability, effects of inorganic salts on pore structure of cement paste were studied in this paper, and possible implications of concrete property with pore structure was also analyzed.
Porestructure And Microstructural Investigation Of
In the present paper, the effect of three different types of nanomontmorillonite dispersions (nmt) on the (i) microstructure as witnessed by scanning electron microscopy, (ii) long term density measurements and (iii) pore structure as determined via mercury intrusion porosimetry of portland – limestone cement formulations have been compared, in an effort to determine the upper.
Cement Slurry Accelerators Mechanism Amp; Chemistry
Many inorganic salts are accelerators of portland cement slurry. chloride salts are used most frequently. other salts that have an accelerating effect include carbonates, silicates (especially sodium silicate), aluminates, nitrates, sulfates, thiosulfates, and alkaline bases e.g., sodium hydroxide (naoh), potassium hydroxide (koh), and ammonium hydroxide (nh4oh).
Effect Of Inorganic Salts On Pore Structure Of Cement
As research basic of influence of salts on concrete durability, effects of inorganic salts on pore structure of cement paste were studied in this paper, and possible implications of concrete property with pore structure was also analyzed. pore structure of paste added cacl2, nacl, na2so4, nano2, ca(no3)2 and ca(no2)2 curing for 3 days and 28 days were tested through mercury intrusion.

Effects Of Recycled Fine Aggregates And Inorganic
Concrete is porous; the partial pores in the internal structure of concrete are generated by hydration products, such as calcium hydroxide, dissolved in water. external harmful substances in the form of gases or aqueous solutions can penetrate concrete. the destruction of the internal structure of concrete leads to problems such as shortening of the service life of concrete as well as the.
