Nofines concrete has low drying shrinkage properties as there is no fine aggregates in the concrete mix (Nader Ghafoori Shivaji Dutta, 1998). During segregation happened, the quality of no
· Production of this type of concrete results in saving of material requirement. Due to absence of fine aggregate or sand, less amount of cement is needed to produce 1 m 3 of no fines concrete. The density of this type of concrete is about 25 to 30% less than the conventional concrete. Therefore it exerts less pressure on formwork.
· I had a surveyor who specialises in Wimpey nofines and he said that if any cracks form around the corners of the windows then you will want to get it investigated or stay away. If cracks are left open, water can penetrate and cause rust to the small amount of steel reinforcement around the windows in the concrete.
· 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.
· No fines concrete is, as the name indies, concrete consisting of coarse aggregate, cement and water fines being omitted entirely. Some of the advantages are impressive. One of the main advantages of no fines concrete results from its relatively .

· The/nternatJona/Journa/of Cemen t Composites and Lightweight Concrete, Volume 8, Number 7 February 1986 Compactibility of nofines concrete Moayed N. AIkhalaf* and Hana A. Yousifl Synopsis Compressive strength and density of nofines concrete mixes are shown to be dependent on the method and degree of compaction.
· The nofines concrete consists of cement, coarse aggregate and water. Thus the fine aggregate or sand is eliminated and such concrete has been adopted for castinsitu external load bearing walls of single and multistorey houses, small retaining walls, dampproofing subbase material, etc. Advantages of nofines concrete Following are the advantages of nofines concrete: As.
Wimpey No Fines properties are concrete constructions, using nofines concrete, the outer structure of the house is cast in situ (on loion) rather than prefabried. Wimpey, no fines/ Laing Easiform are of the most popular of the nontraditional construction build types used in the UK these No Fines and Easiform properties are still hard to mortgage so it can be hard to find a suitable lender.
Nofines concrete. Nofines concrete is obtained by eliminating the fine material sand, from the normal concrete mix. The singlesized 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 lower cement content.
WHAT IS NO FINES CONCRETE ? by Anonymous on 11:05 PM. As the name suggests by itself, nofines concrete does not contain any fine aggregates. This concrete is produced by eliminating fine aggregates from plain concrete. Only cement, coarse aggregate and water are used. The coarse aggregate particles are surrounded with a thin cement paste coating.
No fines concrete is a type of concrete used in early forms of tower blocks and blocks of flats. It 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.
Nofines concrete has been used as an effective method for treating and reducing negative environmental impacts. Problems plagued the initial development, with the pores becoming clogged and stopping the water from passing through, causing ponding and reducing the skid
· Nofines concrete does not contain any fine aggregates. This concrete is produced by eliminating fine aggregates from plain concrete. Only cement, coarse aggregate, and water are used. The coarse aggregate particles are surrounded by a thin cement paste coating. Advantages of NoFines Concrete: The density of no fines concrete is very low.
nofines concrete is low and for this reason walls are usually designed to avoid the use of re i n f o r cement. If re i n f o r cement is included it should be coated with cement grout before being placed in the concrete; in this way it is possible to obtain a bonding strength of aro u n d
"No fines" concrete has little or no fines and contains just enough cement paste to cover the surface of coarse aggregates while maintaining the interconnectivity of voids. Lightweight concrete is characterized by low density (1,400kg/m 3 to 1,800 kg/m 3) and is made of lightweight coarse aggregates.
