Concrete is pretty much the most common construction material, but it is far from being the most green option. As such, scientists and engineers have been searching for alternatives that are more environmentally friendly, and now they may have a solution: cement-free concrete.The global production of cement, a fundamental component of concrete, is the third-largest source of anthropogenic carbon emissions in the world. However, in recent years, various alternative methods for creating greener concrete have emerged. Some have included using industrial waste and steel slag to lower CO2 additives in the mixture, while others have suggested using spent coffee grounds to create stronger concrete with less sand.But now one company has developed a method to create concrete without cement that can be used in commercial businesses. The concrete is potentially carbon-negative and may prevent around 1 ton of carbon emissions for every ton used. If this is true, the cement-free binder will be a significant alternative to Portland cement. As reported by BGR, the new concrete also meets all the industry standards of traditional cement concrete, meaning there is no trade-off in terms of strength and durability.Although it is still early days, the situation appears promising. C-Crete Technologies, a materials science company and the patent holders of the new concrete, have used around 140 tons of the new cast-in-place (pourable) concrete in new construction projects. In September 2023, the company received nearly $1 million, quickly followed by another $2 million, from the US Department of Energy to further develop its technology. It has also received various other awards that are helping it expand its operations.The wider introduction of cement-free concrete into future construction projects has the potential to drastically change the industry's impact on the environment, and while C-Crete appears to be in the minority when it comes to experimenting with these new options at this scale, there is certainly potential that we will see others joining its ranks in the coming years.  

A Colombian resident posted a video on Reddit (see below) of a mysterious incident that he claims happened a few days ago in his unnamed hometown. A mysterious object—whether it was an inanimate object or a living creature remains unclear—flew into the open door of a house at high speed and knocked down a man standing at the entrance. The impact was so strong that the man was thrown out and landed near the steps. He sustained serious cuts from the fall and had to be taken to the hospital, where he received 24 stitches. Weird object knocks out a man. byu/kamm03 inParanormalEncounters The incident was captured on a surveillance camera, and despite multiple viewings in slow motion, the nature of the fast-moving object remains completely unclear. Skeptical internet users believe the description of the video is fictitious, suggesting the video simply shows the coincidental flight of an insect and a person falling out of the door. Others are convinced that something strange genuinely happened. Firstly, the person is propelled out of the door with such force that it appears as if he was hit by a speeding car, and he falls in a way that suggests multiple broken bones. Secondly, a couple of seconds before the mysterious object flies by, a white light flashes in the window of a parked car, suggesting a reflection of the flying object. This indicates it was not merely an insect flying in front of the camera. One user reasonably noted that it would be preferable if the video were fake, as the alternative is unsettling. In the comments, the person who posted the video mentioned that the injured man claims he does not remember what hit him. The author also noted that the house where this occurred is located about 400 meters from the road, meaning it could not have been an object like a wheel accidentally flying off a truck. Additionally, nothing unusual was found in the house after the incident. The post Strange object flew into the door of a house and threw a man out appeared first on Anomalien.com.

In the past, people who migrated from one country or region to another invariably brought seeds with them. This is prudent. But many times, the plants of one ecosystem cannot grow in another, due to temperature or soil conditions. Imagine the problems (hunger) that ensued. The most valuable seeds at the end of a journey, I imagine, were those that could grow the fastest to some edible stage in a variety of new locations, proliferate, set seeds, and repeat. Here, I would like to sing the praises of two modest plants, wild and domesticated in a broad range of USDA … The post Two Inexpensive and Easy Food/Pollinator Crops, by Mrs. Alaska appeared first on SurvivalBlog.com.
