AShotcrete is a method of building a structure using a concrete mixture. A shotcrete mixture likely would exceed the compressive strength of most mixtures used for placed walls because the application of shotcrete requires a much lower water-cementitious material ratio than commonly found in residential wall mixtures.
When used on walls, can shotcrete be of equivalent strength as poured concrete?
ABasically, shotcrete is a method of placing concrete that does not require forms. As a matter of fact, shotcrete requires the concrete mix to be proper every time. With formed concrete walls, the ready mixed concrete going in can be substandard and still appear to be okay. Shotcrete also provides a more dense concrete less susceptible to water penetration.
What is the minimum thickness that shotcrete can be applied?
AThicknesses depend on the structure and surface (surface prep is the key to proper bonding of shotcrete) the shotcrete is being applied to. Depending on the application 1/4 flash coat to 1 inch thickness can be the minimum.
I am looking for any information regarding the use of construction joints for permanent shotcrete wall facing
AIn many experiences, the spacing and design of the joints are the same as you would expect for a cast in place wall. Walls have been constructed with no joint, with contraction and expansion joints, with a joint that is caulked, with joints containing waterstop, and just about anything else you might see in a cast in place wall.
Can shotcrete be painted like other concrete? Can an elastomeric paint, 100% acrylic latex house paint or solvent acryli..
AShotcrete is pneumatically applied concrete. All surface prep work for concrete will be the same for shotcrete applications. Before a recommendation can be made, is this tank going to be painted on the outside or the inside?
I am a general contractor who hired a company to shotcrete a new swimming pool
AOn large swimming pools, it is not unusual to have joints that are left over a weekend or longer. The key is the means by which the joint is dealt with. As with any concrete joint, the surface needs to be clean and free of laitance or other contamination.
