No-fines concrete. No-fines concrete is obtained by eliminating the fine material sand, from the normal concrete mix. The single-sized coarse aggregates are surrounded and held together by a thin layer of cement paste giving strength of concrete. The advantages of this type of concrete are: Lower density. Lower cost due to

No fines concrete is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation
No fines concrete, as the name implies, is simply a concrete product that doesn't contain sand or fine materials. NFC is used to greatly increase gravity wall Once the cement is thoroughly mixed with the aggregate, add water in the volume indicated to the right, do not over water the mix. Rocks should appear thoroughly
Apr 1, 2001 The second category of mixers is continuous mixers . As the name indicates, the materials are continuously fed into the mixer at the same rate as the concrete is discharged. They are usually non-tilting drums with screw-type blades rotating in the middle of the drum. The drum is tilted downward toward
No fines concrete is, as the name indicates, concrete consisting of coarse aggregate, cement and water- fines being omitted entirely. Some of the With no fines concrete the danger of dampness is remote unless there is bad detailing, or a concentration of cement grout in the wall as a result of using too wet a mix. Cracking

The paste,- camelwayposed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. The- camelwayposition or ratio of these ingredients say cement, sand, aggregate varies from one mix to other based on the strength requirement. This method of concrete batching may not be economical.
