Certified Material Testing Products offers the latest products specifically designed for Self Consolidating Concrete (SCC). Self Consolidating Concrete (SCC) is a flowable and non-segregating concrete that spreads and fills a variety of frameworks without the aid of powered vibrations.
The J-Ring Test Set includes all the necessary items to determine the ability of Self Consolidated Concrete (SCC) mixtures to flow around reinforcing structures. Certified Material Testing Products also provide The L-Box for Self Consolidating Concrete, the Static Segregation Column Mold and the V-Funnel Flowability Test Set.
All of our Self-Consolidating Concrete products are in stock and ship today.
This highly flowable, non-segregating concrete has many benefits. With a slump flow of 20 to 30 inches, self-consolidating concrete (SCC) spreads into place, fills your formwork and encapsulates the reinforcement without segregation or bleeding.
You don't need any mechanical consolidation – this versatile concrete consolidates under its own weight. As a result, you enjoy these advantages when using self-compacting concrete:
There are certain applications where using self-consolidating concrete is optimal. For example, it's used for beams and columns, foundations, pumped concrete and other applications where flowing concrete is beneficial to concrete placement. These days, architects are often tasked with creating unique and innovative structures. Concrete has a history of being a versatile material, and self-consolidating concrete has done much to solidify that position, particularly when it comes to architectural concrete.
Additionally, you can use SCC mixtures to mimic various formed surfaces, from wood textures to intricate carvings. Practically any element the architect and owner have in mind can be produced in self-consolidating concrete construction.
Four procedures are used in self-consolidating concrete testing to ensure it's ready to use at your job site. Whether you use a slump flow test, L-Box, J-Ring or V-funnel test, Certified MTP has all the testing apparatus you need.
This SCC testing is conducted using a slump cone. You fill the cone, lift it up and measure the spread of the concrete. The spread should measure from 18 to 32 inches. You will also be looking at the leading edge of the spreading concrete to see whether there's any bleed water or if any aggregates accumulate at the center of the flow.
When testing for self-consolidating concrete, you'll also need to measure the time it takes for the concrete to reach the 20-inch diameter spread after you lift the slump cone. For SCC, it typically takes from two to ten seconds. It takes longer for a more viscous mix, which would be used for congested reinforcement or deep areas. Shorter times indicate a more fluid mixture that needs to flow across larger expanses without obstruction.
Another method of SCC testing is the V-funnel test. It determines how quickly self-consolidating concrete passes through a constricted area. The funnel opening is set to a specific size. You pour the concrete into the funnel and measure the time it takes to flow through the opening at the bottom.
A variation of the slump flow test, the J-ring uses a simulated rebar cage that surrounds the slump cone. You then evaluate the ability of the self-consolidating concrete mix to spread past the cage without segregation.
This SCC testing is used for product development or prequalification. The L-Box test is performed by pouring concrete into one side of the box, then opening a gate to let the concrete flow through the opening on the opposite side, which contains simulated rebar. The depth of the concrete is then measured. The proportional difference is the blocking ratio. (Some tests are performed by timing the flow with a stopwatch.)
Here are some of the commonly asked questions about SCC. If you don't see an answer to the question you have, please contact us and let us know how we can help.
Yes, SCC mixtures are generally more costly than conventional concrete. However, you'll save in other ways, including reduced labor costs, shorter construction times and less wear and tear on your equipment. Plus, you'll enjoy more flexibility – so the added cost of an SCC mix is well worth it.
Self-consolidating concrete was developed by Japanese researchers in the late 1980s.
Essentially, SCC needs to have low-yield stress and high viscosity to ensure it suspends aggregate particles without segregation, excessive bleeding/air migration or paste separation.
Testing concrete to ensure it's properly proportioned for optimal performance is an essential task on any construction site. Make sure your self-consolidating concrete is up to speed with high-quality SCC testing products.
