Two different process of applying shotcrete are,
No
Whether cast-in-place concrete is better than shotcrete depends on the specific application and project requirements. Cast-in-place concrete provides better control over the mix and allows for complex shapes and finishes, making it ideal for structural elements. Shotcrete, on the other hand, is often quicker to apply and can be more efficient for certain applications, such as in tunneling or for sculptural forms. Ultimately, the choice between the two methods should consider factors like project scope, budget, and desired finish.
The coldest temperature at which shotcrete can be successfully applied is typically around 40°F (4°C). Below this temperature, the hydration process can be negatively impacted, affecting the strength and durability of the shotcrete. Precautions such as using heated mix water or protective enclosures may be necessary in colder conditions.

Yes, shotcrete should be water cured to ensure proper hydration and strength development. Water curing helps to prevent the surface from drying too quickly, which can lead to cracking and reduced durability. It's typically recommended to keep the shotcrete moist for at least 7 days after application to achieve optimal results.
Crack patterns in shotcrete refer to the various types of cracks that can develop in shotcrete applications, which is a method of applying concrete through a high-pressure nozzle. These patterns can result from factors such as shrinkage, temperature fluctuations, improper curing, or structural loads. Common crack patterns include hairline cracks, map cracking, and structural cracks, each indicating different underlying issues. Monitoring and addressing these cracks is essential to maintain the integrity and durability of the shotcrete structure.
A lean mix of concrete is a weak mix (ie. Gen 1 or C10 for example). As for how waterproof a lean mix is compaired to a shotcrete mix, it would depent on what mix of shotcrete is used. Generaly speaking, whatever mix of concrete is used if it dose not have a waterproofing agent in it (ie. Sika 1+ Waterproofer for example) it wont be that waterproof. But if you want a staight answer, I would say shotcrete would be more waterproof, only because it tends to be a stronger mix. Regards Colin, a concrete batcher for Tarmac.
Swimming Pool Care for Black Algae I have a shotcrete pool in Sydney Australia and it has done extremely well now for over 17 years as a matter of fact it still seems as good as new. Go with it.
The material you are likely referring to is called shotcrete, not shockcrete. Shock-crete is a flooring material and not used for swimming pools that I know of. Shotcrete is sprayed onto surfaces (like pools) that contains a primer and a type of polyurethane topcoat that contains an aggregate that finishes off looking like concrete in most applications. it is used mainly to apply monolithic linings that have a good chemical resistance. it is often used in pools, tunnels, etc., much like gunite i think its is concrete injected into the ground to firm up supports and the ground.
It is know to be concrete, gunite or shotcrete.
yes. it is just concrete. concrete is used in koi ponds all over.
