SCP Tech Brief: Concrete Curing

ACI 308R-16 Guide to External Curing of Concrete refers to curing as “Curing is an action taken to maintain moisture and temperature conditions in a freshly placed cementitious mixture to allow hydraulic cement hydration and, if pozzolans are used, pozzolanic reactions to occur so that the potential properties of the mixture may develop.” Spray-Lock Concrete […]

SCP and Structural Integrity

  Structural integrity is defined by Dr. Steve Roberts of Oxford University as “the science and technology of the margin between safety and disaster.” When taken in context of the broader idea that structural integrity refers to the ability of a structure to resist loads or other damaging effects from its environment, Dr. Robert’s definition […]

Sustainability in Construction: Going Beyond Using Recycled Materials

Sustainability is a buzzword in construction, manufacturing, and every other industry today. Fundamentally, sustainability is the idea of managing our resources so that future generations have access to those resources. Naturally, this idea brings with it the desire to utilize recycled and renewable materials. Yet in construction, sustainability can also be addressed through dramatically increasing the expected life […]

Reducing Reinforcing Steel Corrosion with SCP

Since the late-1800’s, the use of reinforced concrete has been the most widely used construction practice globally because reinforcement helps concrete in tension. However, one concern of using this practice is the durability and longevity of the concrete due to the corrosion potential of the reinforcement. Corrosion of reinforcing steel is the number one cause […]

Is Spray-Lock Concrete Protection a Bond Breaker?

“Are Spray-Lock Concrete Protection (SCP) products bond breakers?” To answer this question, we need to define a bond breaker and examine how SCP reacts in the concrete matrix. A bond breaker is a product that forms varying layers of separation between contact surfaces. SCP is a penetrating concrete treatment that does not change the surface […]

Calcium Hydroxide Consumption by SCP’s Colloidal Silica

Concrete in service can sometimes be exposed to attack from chemical agents. Two principal factors affect concrete’s durability in chemical attack situations: 1) the concrete’s permeability and 2) readily available reactants in the concrete. When Portland cement reacts chemically with water, it produces several reaction products.  Calcium Silicate Hydrate (C-S-H) is the primary reaction product […]

Polished Concrete with Spray-Lock Concrete Protection Products

The Concrete Polishing Council defines polished concrete as the result of “changing a concrete floor surface, with or without aggregate exposure, to achieve a specified level of gloss.”1 Concrete polishing is a process where the upper paste portion of the concrete surface is removed. Based on the desired appearance, polishing can expose fine and/or coarse […]

Waterproofing Concrete: One-time Treatment vs Topical Treatments

Most waterproofing sealers can be grouped into two categories: topical and penetrating. Before examining treatment options, however, the difference between waterproofing and dampproofing should be established. The American Concrete Institute (ACI) Terminology Committee (TAC 90-02) has changed the definitions of these terms: Waterproof: an idealized property of a material indicating imperviousness to water in either […]

SCP Accelerates Schedule with a Superior Cure for Tukwila’s First High-Rise

The city of Tukwila, WA, just outside of Seattle, has experienced significant growth over the past decade. Washington Place, slated to be complete in 2017, will be the city’s first high-rise. Construction began on the 19-story, 418,000 ft2 building in 2014, and to accelerate the schedule of this large project, Absher Construction chose SCP Treatments […]

SCP is a Home Run for Parties at Cheney Stadium

Peanuts, popcorn, crackerjacks, and more are a big part of baseball culture.  But much of the food and drinks land on the concrete in a baseball stadium, creating ongoing maintenance and safety issues.  And, on ballpark party decks, there’s a greater variety of spillage, including BBQ sauce and grease, creating major cleanup challenges.  That’s why […]
