mortar and concrete incorporating various kinds of fine and coarse aggregate materials is quite needed to understand the shrinkage properties, maintain the structural performances of concrete, investigate the applicability of slag-type aggregates, and save the natural resources as well.
When the high amount of fine aggregate is only used, the 12. Sahmaran ML, Mohamed H, Khandaker MA, Ranade R, Li VC (2009) shrinkage of the mortar is close to that of concrete with Influence of Aggregate …

Fine aggregate of Zone II as per IS: 383-1970 is generally suitable for pumped concrete provided 15 to 30 percent sand should pass the 300 micron sieve and 5 to 10 percent should pass the 150 micron sieve. Fine aggregate of grading as given in Table 2, is best for
The performance of asphalt concrete mixed with 3 types of fine aggregate respectively (i.e. natural sand, limestone, basalt) are compared. The results of Marshall test and rutting test show that the high temperature performance of asphalt mixture mixed with basalt is
1.3. Concrete for pumping The concrete mix design must be correctly proportioned so that the concrete will flow easily and uniformly through the pipe-line. The pipe diameter should be 3.5 to 4 times greater than the maximum aggregate size in the concrete. This

21/8/2019 · Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete. Fineness modulus specifies how much fine aggregate is required in a given mix design.

Aggregate. In addition to the slurry, there are coarse and fine aggregates in the main components of pumped concrete, and aggregates occupy the largest volume in concrete. Aggregate gradation, particle shape, maximum particle size, and water absorption performance will all affect the pumping performance of concrete.
1/1/1994 · Fine aggregate affects many concrete properties, including workability and finishability. Usually, a lower FM results in more paste, making concrete easier to finish. For the high cement contents used in the production of high-strength concrete, coarse sand with an FM around 3.0 produces concrete with the best workability and highest compressive strength.
25/8/2019 · The paper at hand quantifies the influence of aggregate volume fraction on pumping behaviour of concretes with distinct flow behaviours, i.e. plug or …
7. Usually 20 mm size aggregate should be used. For concrete with maximum size of coarse aggregate of 20 mm, the optimum amount of fine aggregate should be between 35 to 40%; and the material finer than 300 micron should be between 15 to 20% and 3% passing through 150 micron sieve of weight of fine aggregate…
How fine aggregate affects concrete mix design. Fine aggregate is a concoction of various materials which are distributed, refined and picked after going through thorough analysis through a sieve test. The aggregate must have the right proportion of course and fine …
26/12/2019 · Fine aggregate is on of the major constituents of concrete which can influence concrete mix design substantially. Various factors such as fine aggregate fineness modulus, moisture content, specific gravity, and silt content affect the mix proportions of concrete.
