In concrete products, concrete aging occurs due to freezing and thawing when moisture enters the concrete gap, and leaching of calcium hydroxide (Ca (OH) ₂) produced by the hydration of portland cement causes large infiltration of moisture. It creates a gap, and freezing causes the water to expand by about 9% by volume. At this time, a pressure of 30,000 psi causes the concrete to crack.

The fly ash combines calcium silicate (Ca (oH) ₂), which is a strong alkaline (PH 12-13) produced by the hydration reaction of cement, with the main component silicate (SiO₂) to produce a cementitious adhesive material, cementitious adhesive material Since it is to reduce the amount of calcium hydroxide leaching to the outside can increase the resistance to freezing and thawing, it is possible to minimize the whitening phenomenon.

Fly ash reduces the moisture required for blending by 2-10% by weight, which limits the penetration of moisture because spherical particles of fly ash reduce bleeding passages and voids, and reduce bleeding passages. It plays a role to increase durability.

The water-repellent admixture is a silicone-based water-soluble agent, which contains 0.3-1% by weight of the cement, increases the early strength within 28 days, and exhibits the water repellent effect, thereby preventing water absorption of the concrete block to prevent contamination by organic substances. Blocks the absorption of sodium hydroxide compounds by winter snow removal.

Water-repellent admixture is a water-soluble silicone water-soluble adsorbent, which fills the pores of the concrete composition and improves the bonding strength of the composition to improve product strength, and fills the pores of the concrete composition to block the water absorption of the concrete block by the water repellent effect. Absorption rate can be lowered to 4% or less, and the water absorption on the surface of the concrete block (1) prevents contamination by organic matter and blocks sodium hydroxide sprayed for winter snow removal, so that the concrete block (1) To increase the corrosion resistance and durability, and to increase the strength of the bonding composition of the concrete composition.
