Wimpey no-fines house - Wikipedia

The Wimpey No-fines House was a construction method and series of house designs produced by the George Wimpey company and intended for mass-production of social housing for families, developed under the Ministry of Works post-World War II Emergency Factory Made programme. "No-fines" refers to the type of concrete used - concrete with no fine aggregates.

No Fines Important Notes on Concrete. generally coarse aggregates Passing 20mm sieve and retaining on 10mm sieve Used for the production of this type of concrete.; Aggregate to Cement Ratio Concrete generally varies without penalty 6:1 To 10:1,; water cement ratio placed within the range of 38 to 0.52, The water cement ratio should be chosen very carefully keeping in mind …

No Fine Concrete [application and advantages] - Structural ...

No fine concrete is a type of concrete used mainly for drainage purposes and as structural fill. It provides better drainage of water through the fill and facilitates the required strength. No fine concrete is a very old technology used in constriction.

NO FINES CONCRETE – ADVANTAGES & LIMITATIONS - …

No fines concrete is one type of light weight concrete. As the name indicates, this a concrete mix without fine aggregate or sand. This type of concrete consists of only water, cement and coarse aggregate.

No fines concrete: a practical guide

No-fines concrete (NFC) consists of coarse aggregate and cement paste. In the hardened state, aggregate particles are covered by a thin layer of cement paste and are in point-to-point contact with each other. At each contact point the paste forms a small fillet; these fillets hold the particles together and give strength to the concrete.

No Fines Concrete No fines concrete. No fines concrete is one type of light weight concrete.As the name indicates, this a concrete mix without fine aggregate or sand. This type of concrete consists of only water, cement and coarse aggregate.

No-Fines Concrete: Use's, Advantages & Disadvantages ...

No fines concrete does not segregate and the capillary movement of water is almost nil. 3. It has better thermal insulating characters due to the presence of large voids. 4. This concrete can be used by dropping from a permissible height. 5. Shrinkage is also lower than normal concrete. 6. It is lightweight.

What is No-Fines Concrete? Advantages and Mix Proportion ...

No-fines concrete, when conventional aggregates are used, may show a density of about 1600 to 1900 kg/m3, but when no-fines concrete is made by using lightweight aggregate, the density may come to about 360 kg/m3. No-fines concrete does not pose any serious problem for compaction. Use of mechanical compaction or vibratory methods are not required.

What is No-Fines Concrete? Advantages and Mix Proportion ...

What is No-Fines Concrete? No-Fines Concrete is a lightweight concrete made up of only coarse aggregate, cement and water by omitting fines (sand or fine aggregates) from normal concrete. Advantages, limitations and mix proportions of no-fines concrete is discussed.

No-Fines Concrete - Allan Block

No-Fines Concrete Backfill can be used with any of the Allan Block Retaining Wall Collections. No-Fines Concrete Backfill typically consists of cement, fly ash, water and coarse aggregate. The quantity of cementitious material is approximately 500 lb/yd³ (297 kg/m³ ) with a water/cement ratio of approximately 0.30 – 0.40.

"No-Fines Concrete" House - what does it mean?

As a simple statement: a "No-fines Concrete" house is one that has been built using concrete without the finer particles. The method of construction was used during the period of 1920s to the 1970s. Quicker and more cost effective to build, instead of laying bricks, the walls were poured as vertical 'slabs' between a board framework ("formwork ...

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 …

No Fine Concrete [application and advantages] - Structural ...

Advantages of No Fine Concrete. Mostly design in hydraulic structures and use as underground drainage without obstruction the functions above the ground. Thermal conductivity is low due to the cavities in the concrete. Acts as insulation due to other less heat transfer with a high void ratio. Useful in construction of external walls.
