UC Davis designed a CoolBot cool room (excellent project for homesteaders!) using rice hull concrete for insulation and a CoolBot controller to keep farm produce fresher. The cool room paid for itself the first year and even helped make a … Continue reading →
This method allows concrete to be pumped into place to build walls without forms. Redimix concrete is delivered to the jobsite, then thickeners and accelerators as required are injected and intermixed in the pumping line, to give the fluid concrete … Continue reading →

Natural builders strive to reduce their use of cement due to high cost and adverse environmental impacts. Sustainability conscious natural builders might use ferrocement, cement plaster or micro concrete roofing tiles which use relatively small amounts of cement, and avoid … Continue reading →
This discovery shows how to make stronger, longer lasting concrete with far less energy. A green type of concrete like this could replace Portland concrete, which is viewed negatively by many due to its adverse environmental impact.
