<p>Concrete protective sol consists of sodium silicate, potassium silicate and water as main components. The sodium silicate as well as the potassium silicate mentioned here are ultra-fine divided solid particles with the diameter of 1 ~100 nm, and their proportion is set as (3.2~4.2) : 1; Furthermore, the proportion of the gross weight of the ultra-fine divided solid particles and the water in the sol is 26~30%: 74~70%.Since the concrete protective sol is prepared by the completely dispersed ultra-fine divided particles, which makes the subject that reacts with the hydrate in the capillary of the concrete changed from ions to the ultra-fine divided solid particles; the dual-segregation protection both for integral and partial are achieved, hereafter on the basis of this mighty dual protection, the strongpoint of the concrete protect sol is result from the combination and conjunction of the sol and gel. The merits of the concrete protect sol can be generally concluded as its ability of anti- corruption that strongly resists the invasion and erosion of the causticity medium, and consequently realizes the long-run stable and effective protection for the concrete structure, indeed improves its durability and prolongs its life-span thereby. Consequently, the maintenance will be greatly decreased.</p> |
