Now fine aggregate = unit weight (density) of concrete − (volume of coarse aggregate + cement content + water content). Hence from Table 4.10, with maximum predominantly larger than 5 mm (0.2 in.) and generally concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3).

For each of the three coarse aggregates (i.e., limestone quartzite and steel slag), two mix designs were evaluated, one with 10 mm coarse aggregate and the other one was made with a 20 mm aggregate size (see Table 3). All concrete mix designs were made with a water-to-cement ratio of 0.3.1 天前The typical weight of 1 CFT (cubic foot) of 10 mm, 20 mm & 40 mm aggregate (stone) is range between 41kg and 46kg (90 to 100lb), or an average of 44kg (97-pound). 1 CFT of 20 mm aggregate weighs about 1 CFT 10mm & 20mm aggregate weight in kg

The construction type depends on the size of aggregate such as 20cm is used as mass concrete-like dams, 63 mm is used for plain cement concrete, 20 mm aggregates are used in reinforced concrete work. Bulk Density of Aggregate. Bulk density is the weight of aggregate needed to fill a unit volume of an container.The objective of this research work is to determine the effect of coarse aggregate blending with 20 mm and 10 mm in a particular coarse aggregate content on short-term mechanical properties (unit weight, compressive strength, MOE and STS) of SCC after 28 and 56 days of curing. And these properties were compared to a conventional Effect of coarse aggregate blending on short-term

Waste coarse slag as a replacement of 20 mm coarse aggregate has been analyzed in this study by performing various mechanical and durability tests and the following conclusions can be drawn from the same. (i) The increase in coarse slag aggregate in concrete mix increased the amount of dosage required to propagate proper The largest size of coarse material that may be used to make concrete is 20 mm. Construction-related aggregates must be chemically inert by nature. Bulk Density of Aggregate in kg/m 3.

The bulk density or unit weight of an aggregate is defined as the mass of the aggregate per unit volume. it is expressed in kg/liter. What is the value of Coarse Aggregate Density? Most of the aggregates possess a relative density within 2.4 2.9 with a similar particle density of about 2400-2900 Kg/m 3 (150-181 lb/ft 3 ).The fine/coarse aggregate ratio was 1:1.22 by weight. The 10 mm/20 mm coarse aggregate ratio was 1/1.20 by weight. The mixing procedure for all mixes was as follows: mix dry sand, stone, rubber (if any), and LECA (if any) for 1 min.; add half of the water and mix for 1 min.; rest for 2 min.; add cement, remaining water, and admixtures, An experimental investigation of the mechanical performance

The typical weight of 1 unit (100 CFT) of 20mm aggregate is approximately 4300 kg (or 4.3 tons). In general, 1 cubic foot of 20mm aggregate has a weight about 43 kg, so weight of 1 unit of 20mm aggregate in kg is 43 × 100 = 4300 kg. The typical weight of 1 unit (100 CFT) of 10mm aggregate is approximately 4400 kg (or 4.4 The fine aggregate is natural sand that has been washed and sieved to remove particles larger than 5 mm, and the coarse aggregate is a gravel that has been crushed, washed and sieved so that the particles vary from 5 to 50 mm in size.The fine and coarse aggregate is delivered separately.
