for natural sand is by crushing natural stone to get artificial sand of desired size and grade 1. The promotional use of artificial sand will conserve the natural resources for the sustainable development of the concrete in construction industry 2. Artificial sand is 3.2 Coarse and fine aggregates Coarse aggregates (i.e. 20 mm and 10 mm) and fine sand were purchased from a nearby crusher in Al-Khoudh area, which are typically the same materials used in normal concrete mixtures. The gradation test conducted on aggregates showed that they met specifications requirements. 3.3 Copper slag

Fill cone to overflowing with drying sand. Lightly tamp the fine aggregate into the mold with 25 light drops of the tamper (Figure 3). Each drop should start about 1/5 in. above the top surface of the fine aggregate. Remove loose sand from base and carefully lift the mold vertically. If surface moisture is still used as the replacement of fine aggregate in the concrete. Concrete cube and beam were casted taking 10% to 25% of plastic as partial replacement of fine aggregate and tested for 28 days of compressive strength and flexural strength of concrete. 1.

of coarse aggregate was 0.5% which was within the normal range from0.1 to 0.6%.The fineness modulus obtained suggest that, the aggregates used had an approximately average sizes of 600m and 12.5mm for fine and coarse aggregates respectively. Thus, the sand used was normal sand since it lies within Zone II of geological grading.

2.3.Sand (Fine Aggregate) Locally available river sand passing through 4.75mm sieve as per IS 383 provisions were used as fine aggregates. Specific gravity 2.85 Fineness modulus 2.79 Referring to 600 micron sieve, the percentage passing is 58.00 % which confirm that fine aggregate belongs to Zone II as per Is 383-1970. TABLE NO. 3 Concrete is a mixture of cement, coarse aggregates, fine aggregates or sand and water. The approximate ratios of these components are as below Based on the ratios and the anticipated cement consumption in the country, the expected requirement of sand

Mar 01, 2017 Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates. Those particles passing the 9.5 mm (3/8 inch) the compressive and split tensile strength. He used concrete mix by using Ordinary Portland Cement, Natural River sand as fine aggregate and crushed granite stones as coarse aggregate, portable water free from impurities and containing varying percentage of waste plastic bags (0%, 0.2%, 0.4%, 0.6% 0.8% and 1.0%).

Fine Aggregate. The particle size ranges from 0.15 mm to 4.75 mm. They can easily pass through a vibrating screen with a 4.75 mm sieve plate and gather on a 0.15 mm sieve plate. Such as artificial sand, natural sand, stone powder, etc. are all fine aggregates. The fine aggregate plays a role in filling the voids with the coarse aggregate in the ... AGGREGATES Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cement-ing medium asphalt to form pavements. Aggregates are the principal load-supporting components of an Asphalt Concrete pavement.

Apr 12, 2020 Sand is used as a fine aggregate in concrete work and is an important engineering material. Sand is a form of silica and natural sand is formed from weathering of rocks and of various sizes or grade and these may be angular or rounded and sharp. There are aggregate retained on each of a specified series of sieves and dividing the sum by 100. The following limits may be taken as guidance Fine sand Fineness Modulus 2.2 - 2.6 Medium sand F.M. 2.6 - 2.9 Coarse sand F.M. 2.9 - 3.2 A sand having a fineness modulus more than 3.2 will be

Extensive choice of Aggregates in different sizes and quality grades, and quality sand of all types of building construction and civil engineering projects used in this country. It is a clean and very cheap alternative to tarmacadam, cobble and concrete. Dust.This is a fine crushed stone not powder like but ... Fine aggregate Coarse aggregate Fine Aggregate When the aggregate is sieved through a 4.75mm sieve, the aggregate passed through it called fine aggregate. Natural sand is generally used as fine aggregate, silt and clay also come under this category. The soft deposit consisting of sand, silt, and clay is termed as loam.
