Efflorescence Protection
Time-Tested Performance Efflorescence is a white crystalline deposit that can form on surfaces of concrete, stucco, brick or masonry. These deposits are water-soluble salts that come from the ground. For water to carry or move the salts to the surface there must be channels through which to migrate in a process called capillarity. Porous materials […]

Concrete Protection
Time-Tested Performance The life of concrete is limited by a number of disintegrating factors: Weathering by rain and frost action is chiefly a function of water-tightness or impermeability, since leach and attack by the carbonic and other acids present in rainwater, and disruption by frost action, depend on the penetration of water into the surface. […]

Concrete Dusting
Time-Tested Performance Test results indicate that abrasion resistance is closely related to the compressive strength of concrete. Strong concrete has more resistance to abrasion than weak concrete. *As shown in the picture, even ‘strong’ concrete is damaged as time takes its toll on unsealed, untreated concrete. *Compression Strength (surface coat only) Results: +15% at 8 […]

Concrete Curing
Time-Tested Performance The chemical action which results in the setting and hardening of concrete is dependant on the presence of water. Although there is normally an adequate quantity for full hydration at the time of mixing, it is necessary to ensure that the water is either retained or replenished to enable the chemical action to […]

Chlorides and Concrete
Time-Tested Performance Calcium chloride has been the most widely used accelerator in the past because of its low cost and predictable performance. However, the use of calcium chloride also comes with these disadvantages: Corrode the reinforcement steel within the concrete, (particularly if the dosage is large and if it is not properly controlled) Reduce the […]
