Nowadays it is very important to make the concrete economical. Therefore the present work has initiated to make the concrete economical by replacing the natural sand by crushed sand in the concrete. From our study it is concluded that different Crushed sand gives different results for compressive strength depending on different quarries and from study of different research paper at 40 to 50 ...
2013-12-24fines as replacement of crushed sand reduces the water permeability and increases chloride-ion permeability. However, the strength characteristics of crushed sand concrete in severe conditions such as in a fire has been little investigated even though the used of crushed sand gradually increased through the worlds. In the present
With the extraction of natural sand deposits the world is over drying up, and there is an acute need for a product that matches the properties of natural sand in concrete Bahoria et al., 2013 ...
2013-8-11The use of up to 20 quarry waste fine as a partial replacement for natural sand in the production of concrete, in Malaysia was also reported 6. Use of crushed granite fines or crushed rock fines as an alternative to sand in concrete production was also reported 7. In Makurdi, the capital of Benue state of Nigeria, in West Africa, the sole ...

2016-9-1Crushed rock sand has surfaced as a viable alternative to Natural River sand and is being now used commonly throughout the world as fine aggregate in concrete. It is manufactured by crushing the quarried stone to a size that will completely pass through 4.75 mm sieve.
2020-8-12The percentage passing 150 microns of manufactured sand is relaxed to 20 while that of natural sand is limited to 10. As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.
In concrete as a composite material, the workability for placement and strength development with age depend upon the properties of the constituent materials and their combined action. The role of fine aggregate on strength and workability has to be
2018-12-11Based on the economic analysis of the test results, replacement of sand with 25 37.5 Crushed Granite Fines is recommended for use in concrete production. Keywords Compressive Strength ,Concrete, Cost, Crushed Granite Fine Sand. I. Introduction Concrete is composed mainly of three materials, namely, cement, water and aggregate. An additional
2017-1-31mix and iv up to 20 of sand replacement with CCB will result in compressive strength that is not significantly different from the control. Keywords Compressive Strength, Concrete, Crushed cow bone, Density, Workability 1. Introduction Concrete is considered to be a universal construction material for many reasons. It is resistant to water when
2019-10-29combined effect of sand fines and watercement ratios effect on the properties of concrete. This paper seeks to address this gap in literature. Materials and Methods Materials The materials used were crushed granite as coarse aggregate, natural pit sand, ordinary Portland cement and water. Physical properties of the aggregates were analysed.
2018-7-92.4 SAND ALTERNATIVES IN CONCRETE elik and Marar 1996 used rock dust limestone 75 mm to replace the sand in concrete for proportions up to 30, with all other ingredients and proportions constant. They concluded that the slump and air content of fresh concrete decreased, as the percentage of dust content increased.
