  • Strength Appraisal Of Artificial Sand As Fine Aggregate

    Strength Appraisal Of Artificial Sand As Fine Aggregate

    Aggregates are divided into natural aggregates and artificial aggregates. According to the degree of thickness, they are divided into coarse aggregate (crushed stone or gravel) and fine aggregate (sand). Due to the non-renewable resources, the mining of natural aggregates is increasingly restricted.

    In addition, the use of artificial aggregates had marginal effect on the crack width distribution of high-strength ECC. The findings in this study demonstrate the feasibility of using artificial fine aggregates in ECC production and provide a new avenue to improve ductility and sustainability for ECC materials.

    In this percentage 40 to 50 proportion of aggregate is fine aggregate (sand). Fine aggregate selection plays vital role in concrete performance and its cost. Lately the need for replacing sand with alternative materials have picked governing serious environmental impact of dredging sand from river bed, also there is huge demand and supply gap.

    Sand aggregate, also named as aggregate sand, or sand and gravel aggregate, which is a wide category from coarse to medium to fine granula that include sand, gravel, crushed stone and aggregate. Sand aggregates are the granular loose material that acts as a skeleton or filling in concrete, and has a variety applications in cement concrete.

    Standard of Aggregate. 1. Fine aggregate should be hard, clean, well-graded. Artificial sand fineness modulus is feasible in 2.4 to 2.8, natural sand fineness modulus should be in 2.2 to 3.0. 2. Fine aggregate in the mining process should be regularly or on a certain number for alkali mining activity test.

    Sand is an important raw material in construction industry. It is the major fine aggregate. There is scarcity of natural sand in large scale because of increased sand mining in river beds leading to lack of natural sand reserves, urban expansion, local legislations and environmental constraints.

    1) Replacement of natural fine aggregate by 60 artificial fine aggregate is the best result because of maximum strength and minimum area of crack. 2) When the replacement percentage of artificial sand is increases than 60 the compressive strength decreases and area of crack increases.

    Jan 29, 2019 The objective of this study is to examine the workability and various mechanical properties of concrete using artificial lightweight aggregates produced from expanded bottom ash and dredged soil. Fifteen concrete mixes were classified into three groups with regard to the designed compressive strengths corresponding to 18 MPa, 24 MPa, and 35 MPa. In each group, lightweight fine aggregates.

    Oct 25, 2021 In addition, replacing fine silica sand (around 950 HKD metric ton in Hong Kong) by artificial fine aggregates (around 550 HKD metric ton in this study) can reduce the cost and improve the sustainability of ECC. Thus, it is worth exploring the use of artificial fine aggregates in the ECC materials.

    Concrete sand Fine aggregate used in concrete. Crushed asphalt The product resulting from the artificial crushing of aspha lt pavement. Crushed gravel The product resulting from the artificial crushing of gravel with substantially all fragments having at least one face resulting from fracture (ASTM, 1988b, Designation C125 -88).

  • Utilization Of Plastic Waste In Concrete As Fine Aggregate

    Utilization Of Plastic Waste In Concrete As Fine Aggregate

    3.3 Fine aggregate Sand conforming to Zone-II (White Sand) was used as the fine aggregate, as per I.S 383-1970. The sand was air dried and free from any foreign material, earlier than mixing. The sand which was locally available and passing through 4.75mm IS sieve is used. The specific gravity of fine aggregate was 2.60.

    Feb 12, 2015 The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. 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.

    Apr 12, 2020 In concrete or mortar, the aggregate is a granular material, it is called fine aggregate when the particles of granular material are so fine that they can pass through a 4.75mm sieve. To increase the volume of concrete it is used in the construction industry and is cost-saving material. It consists of crushed stone and sand and quality.

    Control The Size Of fine Aggregate Raw Materials. The maximum feed size of the sand making machine used to produce fine aggregate (artificial sand) does not exceed 40 mm. When only artificial sand is produced, stone chips (removal of soil and fine powder) or excess coarse aggregate (5-10 15 mm) are used as raw materials. Choose The Appropriate.
