I wonder who approved these blueprints. See world's funniest & most extreme building & engineering fails ever! Concrete on the railroad tracks - insane. Stairs that lead nowhere. Window fails and turns into a wall. Watch your head for places that leave no headroom. A balcony with no door is unbelievable. ATM is so low that you have to crouch down to use it. A tree can go through a house. Bridge fails to have parallel parts. Something is in the way of the fan. Don't block the bike lane. The smallest sink is frustrating.
Engineering fails are unfortunate. Some of these look like they were done just for a joke to laugh at. Who in their right mind would ever pour concrete on top of train rails?
ReplyDeleteConcrete is big business out there. Analysts think that the concrete Superplasticizers market will be worth $7.3 Billion by 2024. The concrete Superplasticizers market is expected to grow from USD 5.1 billion in 2019 to USD 7.3 billion in 2024. The demand is growing for these concrete products in the global concrete industry.
What are concrete Superplasticizers? Superplasticizers (SPs) are also known as high range water reducers. They are additives used in making high strength concrete. Plasticizers are special chemical compounds.
Water–cement ratios of 0.45 to 0.60 are most commonly used. For stronger concrete, lower ratios are used. Adding a plasticizer would increase flowability. Too much water will result in segregation of the sand and aggregate components from the cement paste.
Polycarboxylates are the next generation of superplasticizers. They have brought innovation into the market. They have superior dispersibility. They also have retention effects that are better than the other concrete superplasticizers.
These specific superplasticizers have the capability to significantly reduce water-to-cement ratio by 40% even at low dosage rates. The demand for these products is rapidly increasing in residential buildings, commercial buildings, roads, bridges, dams, ship yards, airports, and high-speed railway constructions. The success of these products is because of their low dosage and high efficiency. They are taking more and more market share.
