Electrical resistivity for concrete prepared with 15% granite powder was reduced due to an increase in porosity developed by poor workability and compactness of concrete. In a similar study, replacement of 15% granite powder as fine aggregate in concrete improved its density, compressive, flexural and splitting tensile strength [20].
This research investigation has mainly focused on the development of cementless concrete, i.e., geopolymer concrete, along with the reutilization of industrial fine granite waste powder (FGWP). FGWP was re-utilized as fractional substitution of natural fine sand (NFS) in the manufacturing of geopolymer concrete in varying amounts—0%, …
Because bulk density of 20 mm aggregate is about 1,550 kg/m3. So, a typical 1m3 of 20mm aggregate weighs about 1,550kg (or 1.55 tonnes). 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 ...
Fine aggregate with the size less than 4.75 mm, is used to ensure the continuity between the cement and ... works reveal that densities values of sands vary in the range of 2.45 to 2.68 for calcareous sand and 2.57 to 2.97 for granite sand. The density is around2.6 for gneiss sand, 2.87 for basalt sand and 2.72 for marble sand. However, for …
Bulk Density Of Aggregates. Jalal Afsar July 30, 2012 Concrete Strength No Comments. Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense …
Specific gravity is 2.61, fineness modulus is 3.2, and bulk density is 1516.6 kg/m3 for fine aggregate. Coarse aggregate has a specific gravity of 2.738 and a fineness modulus of 7.31, both of which are physical characteristics. Super-plasticizer is a dark liquid with a density of 1.09 and a pH of more than 6.

The Specific Gravity of Fine Aggregate Test. ASTM C128 and AASHTO T 84) is a comparison of sample masses in oven-dry, saturated surface-dry (SSD), and immersed conditions.This test method offers alternate procedures to determine specific gravity. Either a volumetric flask or a simple pycnometer can be used for the gravimetric procedure. For …
In particular, the fine aggregate plays a vital role, occupying about 30 % of the total volume [8]. Fine aggregate with well graded particle size fills most of the gap between coarse aggregate and cement, makes cement slurry and coarse aggregate evenly distributed, and further improves the uniformity of concrete.
Six aggregate groups (like 12.5–10 mm, 10–4.75 mm, 4.75–2.36 mm, 2.36-1.18 mm, 1.18–0.6, and 0.6–0.15 mm) were investigated for the particle packing experiment, and the blended coarse:fine aggregate ratio of 55:45 which produced the highest packing density of 0.702, were used in the GPC mixes.
Normally, the specific gravity of RFA is lesser than compared to natural fine aggregates leading to low-density concrete (Lee, 2009; Kou and Poon, 2013; Stefanidou et al., 2014; Martinez et al., 2016). This is due to existence of old adhered mortar (Boudali et al., 2016). Researchers have observed the specific gravity of RFA varies from 2.29 to ...
Granite dust is regarded as a valuable and easy-to-obtain alternative for customary, natural fine aggregate. However, granite dust can be employed in engineered cement composites (ECC). Nevertheless, multiple health and environmental hazards are attributed to it, due to the fact that it is a non-biodegradable material. The current study, …

The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ-ence the concrete's freshly mixed and hardened proper-ties, mixture proportions, and economy. Fine aggregates (Fig. 5-1) generally consist of natural sand or crushed stone with most particles smaller than 5 mm (0.2 in.).
