ROUND TOP, TEXAS — Eco Material Technologies and Hive 3D have announced what they claim is the first community of homes built using additive construction with near zero-carbon cement.
The community, the Casitas @ The Halles, to rise near Round Top, Texas, is a collection of homes ranging from 400 to 900 square feet featuring studio, single-bedroom and two-bedroom models, stated a release.
Eco Material is a producer of sustainable cementitious materials. Hive 3D is active in sustainable additive construction, also known as 3D printing.
Hive 3D will use Eco Material’s cement product called PozzoCEM Vite to build the homes. Previously, Hive 3D created a 3,150-square-foot home using Eco Material’s near-zero PozzoSlag.
PozzoSlag replaces 50 per cent of the portland cement in concrete and has been used in roads and bridges in Texas for over a decade. PozzCEM Vite replaces 100 per cent of portland cement in concrete, has 92 per cent lower emissions and sets faster than traditional Portland cement, states a release.
For the Casitas project, Hive 3D and Eco Materials are creating a system to mix Eco Material’s cement replacement products with locally sourced aggregates onsite using modified commercial mixing equipment. This allows Hive 3D to produce additive material at a much lower cost than other commercially available additive construction mortars, the firm said.
“Hive 3D’s commitment to building the first 100 per cent cement replacement 3-D printed homes aligns with our goal of transitioning the construction industry away from using materials that generate approximately eight per cent of the world’s carbon emissions each year,” stated Grant Quasha, CEO of Eco Material Technologies, in the release. “While we are known as the largest supplier of sustainable cement alternatives for large scale infrastructure projects, we are proud to be able to work with forward-thinking innovators like the team at Hive 3D to provide residential solutions as well.”
Hive 3D has developed its additive construction system worked in collaboration with its technology partner CyBe Construction.
