What is the difference between dry-mix method and wet-mix ...
In dry-mix method the dry cementitious mixture is blown through a hose to the nozzle, where the water is injected immediately. The dry-mix method appears to be better for low volume placements. The nozzleman should pay great attention in adding the necessary amount of water during shooting operation. Wet-mix method involves the pumping of ready mixed concrete to the nozzle.Learn More
Ready-mix concrete - Wikipedia
Ready-Mix Concrete is concrete that is manufactured in a batch plant, according to a set engineered mix design. Ready-mix concrete is normally delivered in two ways. First is the barrel truck or in–transit mixers. This type of truck delivers concrete in a plastic state to the site. Second is the volumetric concrete mixer. This delivers the ready mix in a dry state and then mixes the concrete on site. Batch plants combine a precise amount of gravel, sand, water and cement together by weight ...Learn More
What is the difference between wet-mix and dry-mix ...
In dry-mix applications, all dry materials – including cement, aggregate, and ad-mixture – are mixed together, conveyed pneumatically through a hose and then, at the nozzle via a water ring, water is injected evenly throughout the mix as it is being projected. Generally, dry-mix is used for small to medium volume placements or for conditions with limited vehicular access.Learn More
