ConBlock SH Water Based, Penetrating Reactive Concrete Densifier & Hardener

ConBlock SH is a non-toxic, water-based penetrating concrete sealer made from a proprietary blend of inorganic materials that reacts with Portland Cement Concrete to create crystalline formations within the concrete pore structure. Applying ConBlock SH improves the durability, chemical resistance, and hardness, as well as reducing the porosity of concrete.

Technical Data

PRODUCT DESCRIPTION

ConBlock SH is a non-toxic, water-based penetrating concrete sealer made from a proprietary blend of inorganic materials that reacts with Portland Cement Concrete to create crystalline formations within the concrete pore structure. Applying ConBlock SH improves the durability, chemical resistance, and hardness, as well as reducing the porosity of concrete.

Additionally, ConBlock SH reduces “dusting” on concrete surfaces which is beneficial in preparing the surface for the application of coatings and adhesives. ConBlock SH will not change the color of your concrete and can be polished after treatment to create a glossy sheen. Since ConBlock SH is a penetrating sealer and not a coating, the surface characteristics are virtually unaffected.

FEATURES & BENEFITS

  • Reduces dusting
  • Reduces porosity / absorbency
  • Improves freeze / thaw scaling protection
  • Increases chemical resistance
  • Improves abrasion resistance

PRODUCT TESTING

Scaling Resistance

ASTM C-672 Standard Test Method for Scaling Resistance of Concrete Surfaces Exposed to Deicing Chemicals.

After 50 cycles, the ConBlock SH treated block showed minimal scaling as compared to the control, which showed severe scaling.

Abrasion Resistance

After 40,000 cycles with a Taber Abrasion Tester, the treated concrete (left) was unaffected. The untreated concrete (right) suffered significant abrasion.


ASTM C642 Standard Test Method for Density, Absorption, and Voids in Concrete ConBlock SH passes the 24 hour and 50 day test requirements for absorption.

ODOT SS 841 Proof of Crack Sealing Test (Modified AASHTO T259) The test requires a minimum result of 2 for treated specimens over untreated specimens. ConBlock SH passed with a rating of 8.8 with an average crack width of 0.002” (0.05mm).
