Dense Conventional Gunmixes

Sheffield Refractories Limited Jongun dense gunmixes are refractory concretes that are applied using dry gunite equipment. Dense refractory gunmixes can be quickly installed into areas that would be very difficult to cast or brick. Gunmixes require less shuttering than castables; gunmixes are useful for rapidly repairing linings to extend the service life. Guniteing equipment, supervisors and installers can be hired to install these products. There are many products to chose from and our sales and technical staff will offer advice on materials for different applications
