it feel similar like Roman Concrete just want to share, dont know the component you bring can work for your purpose or not, but at least this may can be an alternative.
Ancient Romans built concrete sea walls that have withstood pounding
ocean waves for more than 2,000 years. Now, an international team has
discovered a clue to the concrete’s longevity: a rare mineral forms
during chemical reactions between the concrete and seawater that
strengthen the material.
Structural engineers might be able to use these insights to make
stronger, more-sustainable concrete, says team leader Marie Jackson, a
geologist at the University of Utah in Salt Lake City. She and her
colleagues report their findings on 3 July in American Mineralogist1.
Modern concrete uses a paste of water and Portland cement, a fine
powder made mostly of limestone and clay, to hold together small
rocks. But it degrades within decades, especially in harsh marine
environments. Instead of Portland cement, the Roman concrete used a
mix of volcanic ash and lime to bind rock fragments. The Roman scholar
Pliny the Elder described underwater concrete structures that become
“a single stone mass, impregnable to the waves and every day
stronger.” This piqued Jackson’s interest. “For me the question was,
how does this material become a rock?” she says.
In earlier work, Jackson and colleagues reported some of the unusual
chemistry of Roman concrete, such as the presence of a rare mineral
known as aluminium tobermorite2. For the new study, the scientists
took samples of Roman harbour concrete to the Advanced Light Source,
an X-ray synchrotron at Lawrence Berkeley National Laboratory in
Berkeley, California, and mapped out the location of minerals in the
The researchers found a silicate mineral called phillipsite, which is
common in volcanic rocks, with crystals of aluminium tobermorite
growing from it. Tobermorite seems to have grown from the phillipsite
when seawater washed through the concrete, turning it more alkaline.
“It's a very rare occurrence in the Earth,” Jackson says. Such
crystallization has only been seen in places such as the Surtsey
volcano in Iceland. As tobermorite grows, it may strengthen the
concrete because its long, plate-like crystals allow the material to
flex rather than shatter when stressed.

concrete. Applying ancient knowledge
Modern concrete-makers could learn from the ancient Romans’ knowledge,
says Nele De Belie, a materials engineer at Ghent University in
Belgium. She and her colleagues have used materials such as fly ash,
produced during the burning of coal, to give concrete ‘self-healing’
properties, whereby the material closes up cracks after they form3.
Fly ash is similar to the volcanic ash that Romans used in their mix.
Jackson has been working to recreate the Romans’ concrete recipe in
the lab. She is also a consultant for a cement company in Nevada that
is using volcanic ash from the western United States to formulate such
“I’m not saying this would be the concrete that would be used in
everyday infrastucture,” she says. “But for materials like sea walls,
we could formulate mixtures with lime and volcanic ash materials in
the way that the Romans did.” The Romans may have got their ideas from
studying how ash from volcanic eruptions crystallized into durable
rock, Jackson says.
