Sometimes concrete bridges are grooved by machine. Bridge decks freeze before roads do because the cold hits both the top and the bottom of a bridge. The grooves increase traction and help prevent sliding when it's snowy or icy. Grooves also lessen the likelihood of hydro-planing. Anyway, the high-pitched noise is caused by the grooves in vehicles tires vibrating against the grooves in the concrete deck.
Pouring a concrete sidewalk without a layer of crushed stone is not recommended. Crushed stone provides essential drainage, helps prevent moisture buildup, and creates a stable base that reduces the risk of cracking or settling over time. Without it, the concrete may be more susceptible to damage from water and temperature fluctuations. For best results, always include a proper base layer of crushed stone.
You can add citric acid and sugar to stop hydration. But then the concrete is unusable and you need to throw it away.
Not really. You will need to seal the concrete surface to prevent concrete dust becoming a problem. Also, the carpet makes the floor warmer to walk on, concrete would feel cold to bare feet.
In order to prevent the washing machine from moving away from its stationary position in a spin cycle. concrete is suspended on spings to counteract overbalances. LOVE FROM RYRY X
The best sidewalk crack filler for repairing cracks in concrete walkways is a polyurethane-based sealant. It is durable, flexible, and provides a long-lasting solution to prevent further damage.

Expansion joints in sidewalks are designed to accommodate the natural expansion and contraction of the concrete due to temperature changes. In the summer, the concrete expands with the heat, causing the joints to narrow. In winter, when the concrete contracts in the cold, the joints widen to prevent cracking and damage to the sidewalk.
So the water you drive through will be channelled through the grooves to prevent aquaplaning.

No, you're not since the sidewalk is technically not your property. The city where you live is the one responsible for clearing and/or placing salt on the sidewalk to prevent ice.
To prevent water pooling and damage under your sidewalk, you can install a drain system by digging a trench alongside the sidewalk, placing a perforated pipe in the trench, covering it with gravel, and directing the water towards a safe drainage area. This will help to efficiently remove excess water and prevent damage to your sidewalk.
To prevent sidewalks from cracking in random spots and breaking apart, builders make lines in sidewalks. The technical term for sidewalk lines is contraction joints. Contraction joints are placed in fresh concrete before the concrete dries and has a chance to create its own joints, which we call cracks.
salt lowers ice's melting point
If a sidewalk had no cracks on a hot day, it could potentially expand due to the heat. The lack of cracks would prevent the sidewalk from accommodating this expansion, potentially causing it to buckle or warp. This could lead to damage and make the sidewalk uneven or unsafe for pedestrians.
Honeycombs in concrete are empty spaces that decrease the structural integrity of the concrete. These can be eliminated by rolling the concrete tight after pouring it.
