( 6 in.) coarse aggregate. Aggregates in Concrete. Professor Kamran M. Nemati Winter Quarter 2015 5 Concrete Technology Aggregates for Concrete Concrete Technology 9 Natural mineral aggregates, i.e., sand and gravel have a bulk density of 95 to 105 lbs/ft3 (1520 - 1680 kg/m3) and produce Normal-Weight concrete (NWC).

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.

Answer / vinoth. Cement = 1440 Kg/cum Sand = 1450 to 1500 kg/cum Steel = 7850 Kg/cum Water = 981 kg/cum Aggregate = 1450 to 1550 kg/Cum

Most common aggregates ( Ex: Sand, Gravel, Crushed stone) Produce normal-weight concrete 2200 to 2400 kg/m3 Lightweight Aggregate Expanded (Shale, Clay, Slate, Slag) Produce structural lightweight concrete 1350 to 1850 kg/m3 And (Pumice, Scoria, Perlite, Diatomite) Produce lightweight insulating concrete— 250 to 1450 kg/m3

Step-2: Calculate the weights of materials required in 1 Cum concrete. Density of Cement (loose) = 1440 kgs/cum. So weight of cement required = 1440 X 0.22 = 316.2 Kgs or 6.32 bags. Density of Sand = 1600 Kgs/cum. Weight of Sand required = 1600 X 0.44 = 704 kgs. Density of Aggregate = 1450 kgs/cum. Weight of aggregate required = 1450 X 0.88 ...

Quantity Of Cement, Sand, & Aggregates For 1000 sq ft Slab? To calculate the quantity of cement, sand, and aggregates required for a flat slab first we need to calculate the volume. ... So by multiplying the quantity of cement with the density of cement, we will the get quantity of cement in terms of kilograms. Unit weight or Density of cement ...

Cost of Concrete mix per is calculated on the basis of unit cost of each ingredient material in the mix. The following market rates have been taken for Cement, Sand, Coarse aggregate, Admixture and a nominal cost for water.

Home / Concrete Technology / Calculate Quantities of Materials for Concrete -Cement, Sand, Aggregates Quantities of materials for concrete such as cement, sand and aggregates for production of required quantity of concrete of given mix proportions such as 1:2:4 (M15), 1:1.5: 3 (M20), 1:1:2 (M25) can be calculated by absolute volume method.

Concrete Mix Design:-Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength.

Normal concrete PCC - 2350 to 2450 kg /cu.mt. Normal concrete RCC - 2450 to 2550 kg/cu.mt. Coarse aggregate - 1350 to 1500 kg /cu.mt. Fine aggregate - 1500 to 1700 kg/cu.mt. This are ingeneral. It may change little bit. Unit wt of concrete 2300 to 2500 kg/Cubic meter volume . Unit wt of sand around ...

Depending on the particle size distribution, specific gravity and density of sand and gravel, the amount of each of them to fill the volume of concrete will be different.

Perlite concrete can be made with a dry density of 320 kg/m3 or with the addition of sand or other aggregates up to 1440 kg/m3. The lower the density, the higher the insulating value. For most uses to maintain a proper balance between insulation value and compressive strength, a 1:6 (one part Portland cement by volume to 6 parts perlite by ...

aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 5-3) are used to produce struc-tural lightweight concrete with a freshly mixed density

Our aggregates are locally mined and used in construction. We have stone dust, sand, gravel, crushed stone and recycled concrete. ... including stone dust, sand, gravel, crushed stone, and recycled concrete. Due to the relatively high ... or a custom density selection. The Base Rock and Drain Rock selections will fill in the density of the rock ...

These variables determine strength, density, as well as chemical and thermal resistance of the finished product. ... Pervious concrete is a mix of specially graded coarse aggregate, cement, water and little-to-no fine aggregates. ... of cement, sand and water.

Density of Some Common Building Materials These values for density of some common building materials were collected from sites across the Internet and are generally in agreement with multiple sites.

The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.

Answer / hrishikesh. 1440 kg/m3 ... cement density-1440 kg/m3 Sand density - 1600 kg/m3 10mm&20mm density- 1540-1580 kg/m3.

Concrete Aggregates sand, cement, coarse, fine, gravel, density and strength ... In this way, the pile of concrete resulting from a mixture of cement, sand, and gravel will be only slightly larger than the original pile of gravel. ... and the weight and density of the concrete increased. The follow ing figures illustrate how voids may be ...

Aug 19, 2015· and the bulk density of aggregate depends upon their packing, the particles shape and size, the grading and the moisture content.For coarse aggregate a higher bulk density is an indication of fewer voids to be filled by sand and cement.

Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.
