There are many reasons why concrete can crack, and the good news is this can entirely be prevented. Thanks to the new technology in concrete mix, some types of concrete can resist the all-too-common unsightly gaps.               National Ready Mix Concrete Association           

New Atlas shared this New Generation Concrete Technology that bends instead of cracks.

“Concrete may generally be a good choice for sidewalks, but it is a brittle material – this means that it needs to be poured thick, in order to keep those sidewalks from cracking under pressure. Scientists from Singapore’s Nanyang Technological University, however, are developing an alternative. They’ve created bendable concrete that they say could be easily applied in the form of relatively thin, light paving slabs.”

Other means to prevent cracking

The website Commercial Real Estate shared information on how to prevent cracking.

“There are technologies that can address the problem of steel corrosion, such as cathodic protection, in which the entire structure is connected to a rust-inhibiting electric current. There are also interesting new methods to monitor corrosion, by electrical or acoustic means. Another option is to treat the concrete with a rust-inhibiting compound, although these can be toxic and inappropriate for buildings. There are several new non-toxic inhibitors, including compounds extracted from bamboo and bacterially derived ‘biomolecules.’”

For the website The Constructor, prevention is the key in avoiding cracks in concrete.

“A low water cement ratio will affect the quality of concrete. W/C ratio is weight of water to the weight of cement used. A lower w/c ratio leads to high strength in concrete and lesser cracks. W/C ratio shall not exceed 0.5 in concreting, which reduces the workability of concrete which can be covered by use of plasticizer or superplasticizer. Less water content increases the durability of concrete Concrete expands and shrinks with changes in moisture and temperature. The overall tendency is to shrink. Shrinkage is the main cause of cracks, when concrete hardens it evaporates the excess water and thus shrinks, so lesser the water content, lesser is the shrinkage.”

Cement Trucks are vehicles you cannot not notice.

After all they are huge, and their imposing big mixer that moves as it moves is definitely something no driver or pedestrian could miss. National Ready Mix Concrete Association 

Media outfit WPXI published a report that will make just about anyone’s jaw drop — a concrete mixer being driven by an 11-year old boy.

“The boy flew through town, reaching speeds up to 70 mph and hitting both a Minnesota State Patrol car and Kasson Police car. The truck’s front right tire went flat, but the ride didn’t stop there. The boy drove off the highway and went back to the side streets of his hometown.”

Crushed

Autoblog meantime shared an article on a sports car that had been crushed by a concrete mixer.

“Three people were severely injured in the crash, one critically. All were taken to area hospitals and are recovering from their injuries. The fact that the driver and passengers survived such a catastrophic crash is a testament to the i8’s safety. The carbon-fiber body and aluminum chassis held up remarkably well under such an intense crash. For those of you who find this sight too terrible to behold, check out the video below for some happier times with the i8.”

How to Care for Concrete Surfaces

Make Concrete Last Longer

Caring for concrete surfaces. (Photo Credits)

Concrete may be a very resilient building material but it still needs caring.

Pressure Wash Cincinatti shared with its readers ways to care for concrete surfaces. National Ready Mix Concrete Association  

“While concrete is definitely a hard and durable surface, many people fail to realize that it is at the same time a porous surface. One of its biggest enemies is water, whether in the form of rain, snow, hail or ice. Over time, exposure to water causes the surface of the concrete to flake and chip. Normal weather conditions will cause the problem to worsen and can lead to the development of cracks in your concrete. Eventually, dust, dirt, and seeds will gather in the cracks. This is the ideal environment for grass and other weeds to grow. When this happens, the cracks become deeper and wider. When they freeze and thaw in cold weather, the concrete around the cracks can heave, creating an uneven and possibly dangerous walking surface.”

Concrete Floor Care

Liquid Floors also shared ways to care for concrete flooring.

“Polished concrete floors are an attractive choice for any industrial or pharmaceutical warehouse. Polished concrete floors can be personalized to fit your business’s needs with custom colors to match existing decor, logos, and lines to manage traffic flow. With proper care, a polished concrete floor should maintain its sheen for many years before needing another polishing. You may think that because these floors are tough that you can skimp on maintenance. We have four maintenance tips that you should never overlook.”

Cracking Concrete

What causes cracks in concrete?

Concrete may be one of the strongest building materials there is but can still be subject to cracks.

Civil Engineering Daily shared 10 reasons why concrete surfaces may crack.

“Shrinkage can cause cracking if not controlled during mix design and curing stage. Shrinkage can become critical in high strength concrete because of low water/cement ratio and also because of use of Mineral Admixtures.”

Read about the nine other reasons here.

More reasons

The website Houzz also offered some possible readons for the cracking. National Ready Mix Concrete Association     

“How is it possible that the concrete that looks so stable and gorgeous in this backyard will certainly crack somewhere as the years go by? Forces such as soil upheaval, expansion and freeze-and-thaw cycles all guarantee that your perfect concrete patio won’t stay perfect forever.
But more immediate forces are most commonly responsible for the early, hairline cracks that can blight concrete slabs almost as soon as they’re poured.”

The website Techeblog.com meatime featured a solution to cracking concretes in one of its published posts.

“Fixing cracks in concrete can be a real pain, but thanks to scientists in the Netherlands, lead by Henk Jonkers, that will be a thing of the past. The team has created a bio-concrete blend with water-activated bacteria – kept in tiny pellets – that can patch up small cracks and holes in cement. That’s right, the bacteria would eat food provided in the concrete mixture to combine calcium with oxygen and carbon dioxide to form limestone”

Painting concrete may seem like an easy chore but there are techniques to make sure that the task is properly carried out.

Australian website Lifestyle gave some tips to ensure that the surface being painted on will look perfect. National Ready Mix Concrete Association 

“Prepare the surface you’re painting. Clean off lose bits of debris that have stuck to the concrete. If there is any oil on the surface, use a strong detergent and wash it down thoroughly. Let it dry completely before starting your paint job! Any moisture trapped between the paint and the concrete could cause it to blister. “

Uncomplicated Concrete Painting Procedure

DIY Network meantime shared a step-by-step guide on how to paint a concrete floor.

“The concrete floor must be completely dry before beginning this project. If your floor shows any signs of water seepage, the source of the water must be eliminated before starting. Some of the materials used for this project require special masks and other equipment, due to fumes. Please read all product labels carefully. Allow the floor to dry thoroughly after each coating is applied. Thoroughly wash floor with a degreasing solution. Rinse several times until mop is clean. Allow to dry for several days.”

Modern Concrete Structures

Built to Last

Strong and Modern. (Photo Credits)  

Modern Concrete Structures abound especially in the metropolis, and as more and more technological developments are being discovered, concrete becomes even stronger.

Architizer published a feature on the most modern concrete structures in South Korea. National Ready Mix Concrete Association 

“While they are atypical, unorthodox, and endearingly rare, the following seven buildings explore South Korea’s emerging design culture and conceptual design approaches. With innovative spatial arrangements and material combinations, the structures are drawn across various scales, typologies, and contexts. Examining the human experience of envelopes and transitions, each project establishes real and perceived boundaries between interior and exterior space. Just as concrete’s character changes based on its aggregates, these South Korean projects begin to express the country’s architectural, social, and cultural values through the lens of local sites.”

Out of this world

Architectural Digest meantime shared a concrete structure that is literally out of this world.

“Formulated to survive Mars’s harsh conditions—subzero temperatures, low gravity, and thin atmosphere—the concrete is a mixture of Martian soil and molten sulfur that can easily be remelted and recycled. And most important, it can be made without water, which will be in limited supply in a human settlement. The breakthrough, although years ahead of any practical use, will make the future human explorers of Mars less dependent on shipments from Earth. It also creates an opportunity for a new wave of design: Engineers can turn to mud-brick houses and other earthen construction to inspire structural development on Mars.”

IEEE Spectrum meantime shared about an ultra-modern concrete structure this time built by robots.

“As long as you keep feeding it bricks, it can work continuously, placing 1,000 bricks an hour based on a CAD drawing. This works out to the shell of a new house every two or three days, complete with channels for plumbing and electrical. The whole system is mobile (although it relies on external localization), meaning that you can use it pretty much anywhere. And with a development cost of just $7 million, it might actually be commercially viable.”
