Low-Density, Low-Strength Concrete
Engineered to dramatically and uniformly reduce the weight of concrete without requiring airentraining admixtures, SYNTHEON® ELEMIX® ExB™ concrete additive leverages its dynamic structure
and dispersion characteristics to become an integral part of the concrete matrix. This results in reliably
consistent, high-performance lightweight concrete no matter how high or far it is pumped. ELEMIX
ExB can be used in a variety of applications including geotechnical underground engineering as a
low-density, controlled, low-strength material.
BACKGROUND
Cellular concrete mix designs create a low-density and relatively lower compressive strength concrete
when compared to conventional concrete. The typical density range of neat cement cellular concrete
mixes is 20 - 60 lb/ft3 (320 - 961 kg/m3), which develops a corresponding compressive strength range
of 50 psi - 930 psi (345 - 6408 kPa).
MIXES
Mixes with ELEMIX ExB additive can be designed to reach densities lighter than soil but with equivalent
or higher compressive strengths. This allows the concrete to flow into areas that are difficult to reach,
yet still provides an equivalent 100% compaction.
Mixes designed for low strengths are able to be excavated using hand tools or machinery. The low unit
weights provide low resultant pressures on any retaining structure.
Mixes of ELEMIX ExB additive can be designed with densities ranging from 36 pcf to 100 pcf and
compressive strengths ranging from 200 psi to 1200 psi. The actual strengths and density of the
ELEMIX ExB additive low-density concrete is determined by the quantities of ELEMIX ExB additive
placed in the mix.
Mixes can be tailored to the exact specifications required by the engineer for the specific application.
ELEMIX ExB additive may be added at the ready-mix plant or on the job.
WHY ELEMIX ExB ADDITIVE?
ELEMIX ExB additive can improve the physical characteristics that make low-density concrete
successful – highly flowable/pumpable, with load-bearing capacity – and add the element of
consistency batch-to-batch, job-to-job, anywhere in the world.
ELEMIX ExB can achieve superior low density, low strength concrete by using a high volume of ELEMIX
additive with minimal engineering. ELEMIX ExB additive is inert and the performance of ELEMIX ExB
additive is not impacted by the increased carbon content in high loss on ignition (LOI) fly ash.
The versatility of the ELEMIX ExB additive allows the ready-mix producer to control the quantity of
ELEMIX ExB added to the truck. This allows for the mixing of load sizes from a full truck to a short load.
On the jobsite there is no additional equipment required from traditional concrete placement. For
remote or hard-to-reach locations, a concrete pump can be used for placement as well.
POTENTIAL APPLICATIONS
Concrete mixed with ELEMIX ExB additive can be used for many applications. Any volume of low-density,
low-strength concrete made with ELEMIX ExB can:
•Fill rather than remove miles of abandoned pipelines, saving time and cost.
The concrete mix must have enough strength to compensate for future complete
deterioration of the pipeline. This can be accomplished without heavy equipment and
minor excavation.
•Fill tunnels, mines and other cavities that are subject to geological pressure.
When set, the concrete mix forms a stable, permanent mass stronger than the
surrounding soil. Yet, its low-strength allows easy removal, should it become
necessary in the future.
•Provide a stable lightweight base for building over subway tunnels and
other in-ground infrastructure. Replacing topsoil with lower density concrete
reduces weight and permits larger structures to be built over these areas. It can be
excavated and prevents compaction or settling.
•Provide load-reducing fills for mechanically stabilized earth (MSE) and
retaining walls or bridge approaches and embankment fills.
•Provide low-density layers for other applications.
BENEFITS AT A GLANCE
Low-density mix designs made with ELEMIX ExB additive are:
•Easy to excavate
•Load-bearing with no compaction required
•Highly pumpable for very long distances
