Abrams’ Law – a rule on concrete stating that with the provided materials, testing conditions, and curing, the strength of concrete is oppositely related to the ratio of cement to water. Low cement to water rations create higher concrete strengths
Accelerator – a chemical substance that is placed on a concrete mixture to minimize the set time through increasing the hydration rate
Antiquing – a technique used for color layering that gives decorative concrete surfaces a mottled or aged appearance.
Bleeding – water that emerges on freshly placed concrete’s surface caused by segregation. Bleeding could interfere with the setting of the finishing touches
Blistering – the development of blisters in coatings or toppings and the loss of the bond with the substrate. With concrete surfaces, blistering is a result of moisture vapor transmission or moisture problems
Broom Finish – a type of surface texture that is achieved by pushing a broom on top of freshly placed concrete (this is used for sidewalks and driveways)
Concrete – a mixture of cement, sand, water, coarse aggregate and fine aggregate
Calcine – heating a substance to an elevated temperature but under the fusing or melting point, thus causing oxidation, reduction, moisture loss, and the decomposition of carbonates and other compounds
Cement – a construction material produced by grinding clay and calcined limestone to a fine powdery substance that can be used as an ingredient for making concrete or mortar, or combined with water and poured to a set to create a solid mass
Cast – to create an object by using concrete in fluid form and pouring it into a mold, then allowing it to harden.
Decorative Concrete – concrete enhanced by texture, pattern, color or a mixture of ornamental treatments
Densifier – a hardening liquid chemical, which penetrates into concrete when applied, to help densify and solidify the surface and offer additional protection from staining and water penetration
Reinforced Concrete – concrete construction containing welded wire mesh or steel rebar embedded inside to offer more tolerance to flexural stress and tension.
Another type of reinforced concrete contains glass fibers / glass sheeting. It’s called GFRC – Glass Fiber Reinforced Concrete. The glass fibers add tensile strength, which is also reinforcement and this is the type that is usually used for projects such as architectural precast concrete.
