Amerimix supplies mortar mix to New Standard Homes for 3D-printed concrete homes

Amerimix, a subsidiary of Oldcastle APG, has taken a significant step in the advancement of 3D printing of concrete homes in collaboration with New Standard Homes. In Shiner, Texas, three homes have been successfully built using this technology. This represents an important step forward in meeting the increasing demand for affordable, high-quality and efficient housing.

At the centre of this project is Amerimix’s specially developed 3D printing mortar mix. This was specifically tailored to the requirements of 3D concrete printing and ensured precise and fast processing.

“We are looking at cutting-edge technology to help shape the future of the building industry,” said Jason Dean, SVP of Pro Sales at Oldcastle APG. “We want to align with builders and developers to achieve their customers’ dream living spaces, while creating job efficiencies and cost savings.”

The construction process was carried out using a large-format portal 3D printer manufactured by COBOD and hired from PERI 3D Construction. Around 150 bags of the customised AMX300 mortar mix were used. The initial results were promising: the first 1,200 square foot house was printed in around six weeks, while the subsequent, larger houses (1,500 square feet) were completed within three to three and a half weeks. This time saving resulted from the continuous optimisation of the printing process, particularly in terms of shift speed and machine set-up.

“We’re not just building houses; we’re creating homes that elevate living standards with cleaner lines, superior finishes, and greater durability,” said Rex Rizk, owner, New Standard Homes. “The goal is to set a new benchmark for sustainable, more affordable housing in architectural styles that folks want to live in.”

This is feasible thanks to the ongoing improvement of the printing process. Concrete is particularly characterised by its durability and sustainability and is therefore an ideal building material.

“We are at the forefront of reinventing how our world is built,” said Rizk. “This technology is a key component of our vision to provide better homes for everyone.”

This project will make an important contribution to modernising the construction industry by combining innovative technologies with society’s need for affordable housing.
