Effect of Dust Contain In Artificial Sand on Compressive - Artificial Aggregate - an overview | ScienceDirect Topics
Here I have explained different types of concrete with advantages and disadvantages of concrete. It is the widely used construction material and is obtained by mixing cementitious material, sand, aggregate, water, and admixture (if necessary) in the required proportion. It is prepared at sie i.e at the place of building structure or maybe pre ...The use of concrete represents about 65% of all the building materials in the world [4]. This leads to overproduction of cement that results to environmental issues such as water pollution [5 ...

STUDY OF LIGHTWEIGHT CONCRETE BEHAVIOUR - HIGH-STRENGTH STRUCTURAL LIGHTWEIGHT CONCRETE
Artificial sand confirming to all four zones was having specific gravity of 2.76 also used to full replacement of natural sand. The fineness modulus of coarse aggregate, natural sand and artificial sand was 7.81, 5.18 and 4.62 respectively. The water absorption was 0.50% and 0.52% for coarse aggregate and natural sand respectively.The Civil engineers, Architects, Builders, and Contractors agree that the river sand, which is available today, is deficient in many respect. It does content very high silt fine particles (as in case of Filter sand). Presence of other impurities such as coal, bones, shells, mica and silt etc makes it inferior for the use in cement concrete.

concrete mix was proportioned to achieve a 28-day compressive strength of 25 MPa. Other concrete mixes were proportioned to replace 25% and 35% of regular concrete sand with clean/new foundry sand and used foundry sand by weight. Concrete performance was evaluated with respect to compressive strength. Objective: 1.Natural processes have always cleansed water as it flowed through rivers, lakes, streams, and wetlands. In the last several decades, systems have been constructed to use some of

The type of concrete in which steel fibers 10 to 20 microns in diameter and 10 to 50 mm in length is used. Fiber increases resilience, tensile strength, flexibility, and other qualities. The fibers may be of different materials like steel, polymer, glass, carbon, or even natural fibers like coconut fiber.Table 2: Properties of Natural and Artificial Sand Property Natural Sand Artificial Specific Gravity 2.6 2.90 Fineness Modulus 2.78 2.97 Bulk Density kn/m3 15.60 17.62 Table 3: Sieve Analysis Details of Natural and Artificial Sand Percentage Passing IS Sieve Natural Sand Artificial Sand 4.75 mm 96.2 95 2.36 mm 88.4 79 1.18 mm 65.8 55 600 micron ...

Development of High Strength Concrete using Artificial - BUILDING MATERIALS - SAND
Two grades of concrete M20 and M25 having nominal mix proportion of 1:1.5:3 and 1:1:2 respectively were used by weight and w/c ratio was fixed according to the slump requirement of 60mm. For this concrete mix, quarry dust was added for replacement of sand from 0% to in step of 10%.Before we get into the advantages and disadvantages of manufactured sand, what exactly is manufactured sand? Manufactured sand is sand produced by crushing rocks, quarry stones or larger aggregates pieces into sand-sized particles. Natural sand, on the other hand is the naturally formed sand extracted from river beds.

Comparison of Physical Properties between Natural Sand and - CEMENT and CONCRETE TECHNOLOGY
Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are well-rounded and are usually nearly spherical. Spherical particles decrease the percentage of voids within the concrete mixture so no additional paste is required to fill these voids. Well-shaped natural sands are ideal for workability of mixtures.Yield is the volume of fresh concrete produced from known quantities of component materials, generally expressed in cubic yards or cubic meters. Advantages of Concrete xConcrete has many environmental advantages, including durability, longevity, heat storage capability, and chemical inertness.

The Pros and Cons of Manufactured Sand - The Screed Scientist® - Crushed Sand vs. Natural Sand: Make the Right Choice!
5. Concrete with artificial sand and aggregates design results are satisfactory. 6. Cube strength of Narmada sand concrete is found to be less then artificial sand. 7. Workability is more in case of natural sand made concrete as compared to artificial sand. Results obtained after …gravity. And tests on fresh concrete using manufactured are also tested. The results of the tests are compared with natural sand. This paper puts forward the suitability of manufactured sand to fulfill the unavailability of natural sand. Therefore manufactured sand can be used as an alternative for natural sand which maintains the eco balance.

Advantage of Crush Sand Crush sand is easily available in villages, and cities also . Landscape Architecture and Regional Planning 2017; 2(1): 13-22 15Aerated concrete does not contain coarse aggregate, and can be regarded as an aerated mortar. Typically, aerated concrete is made by introducing air or other gas into a cement slurry and fine sand. In commercial practice, the sand is replaced by pulverized-fuel ash or other siliceous material, and lime maybe used instead of cement [2].
