siliceous sand and stone dust were used as fine aggregate, with the coarse aggregate being basaltic, whose physical characteristics are presented in Table 1 Figure 1. It can be observed that the stone dust presents a high fineness modulus, greater than the limit recommended by Brazilian standard NBR 7211. 10 Nevertheless such material can be

The workability of fresh concrete was measured in terms of slump values. To obtain the required slump value super plasticiser 1.0, 1.3 and 1.6 of weight of cement is added. ... The results were compared for concretes with natural sand to that of quarry stone dust as fine aggregate.

amount of air, water, cement, and fine aggregate that is, the mortar fraction should be about 50 to 65 by absolute volume 45 to 60 by mass. Rounded aggre-gate, such as gravel, requires slightly lower values, while crushed aggregate requires slightly higher values. Fine aggregate content is usually 35 to 45 by mass or

Different Types Of Aggregate And Their Uses

Type 1 Crushed Concrete - 50mm down to dust. Best used as a sub-base for roads, underneath blocks, as well as layering in between concrete or tarmac and as a hard core for projects such as car parks. 6F2. Type 3 Crushed Concrete - 0-63mm reduced fines. Oversized Clean Crushed Concrete -

Designing and Proportioning Normal Concrete Mixtures

sometimes be achieved through the use of crushed stone aggregate rather than rounded-gravel aggregate. The most desirable fine-aggregate grading will depend upon the type of work, the paste content of the mixture, and the size of the coarse aggregate. For leaner mixtures, a fine grading lower fineness modulus is desir-able for workability.

Designing and Proportioning Normal Concrete Mixtures

The function of the fine aggregate is to assist in producing workability and uniformity in the mixture. The river deposits are the most common source of fine aggregate. Now-a-days the natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. The Quarry dust may be used in the place of river ...

Type N General all purpose mortar with good bonding. Easy to work with. Used to build stacked walls or veneer work. Type S General all purpose mortar with higher bond strength. Stickier than other types which makes it ideal for veneer but its also used for stacked walls. Type M High compressive strength.

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 pumped concrete.

Stone Dust Stone dust was collected from Tirupati Stone Crushers local stone crushing units. When it was collected, it was dry and had to be sieved before being mixed into concrete. Table 2 shows the results of the sieve analysis of stone dust. Stone dust had a specific gravity of 2.50 and water absorption of 1- 1.40 percent.

18 Factors Affecting Concrete Quality And How to Deal

Jul 12, 2021 The aggregate should firstly ensure that the quality of the concrete meets the requirements and then take the material locally or nearby to minimize the cost as far as possible. The aggregate in concrete is mainly composed of sand fine aggregate and stone coarse aggregate.

18 Factors Affecting Concrete Quality And How to Deal

Sep 01, 2016 Crushed rock sand has surfaced as a viable alternative to Natural River sand and is being now used commonly throughout the world as fine aggregate in concrete. It is manufactured by crushing the quarried stone to a size that will completely pass through 4.75 mm sieve.

Quarry stone dust the tests are conducted. Results so obtained for the tests conducted on cubes and prisms for M25 and M40 grades of concrete with various dosages of super plasticiser at 7days and 28 days were tabulated. The results were compared for concretes with natural sand to that of quarry stone dust as fine aggregate.
