The paper indicates that with further more trials of design mix the cement consumption can be optimised for use of crushed sand without adversely affecting the strength of concrete compared to the concrete cast using natural sand. The results obtained in this study will encourage the engineers and contractors to use the crushed sand for making

The 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.

two different methods of concrete mix design amidst other methods for construction work (Highways Building) 1112 . The aim of this research work is to examine the similarities and differences (if any) between the ACI and the DOE methods of concrete mix design using crushed and uncrushed coarse

Design of Concrete Mix. Mean strength = (50 / ) = 63 MPa Reference number ()= 25 Water cement ratio (fig 5) = For a 10mm maximum size aggregate and very low workability the aggregatecement ratio for the desired workability (table1) = The aggregates are combined by the graphical method as shown in figure 6 so that 30 percent

Characterization of Crushed Concrete Materials for Paving and Non . The test program identified aggregate properties mix design properties basic mechanistic properties workability A 1977 study by Buck found that the use of crushed concrete fines as a sand material requires an economical due to costs associated with transporting the material from the stockpile to the job site 32

May 17 2017 To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1 3 that mean 1 part of cement part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow

aggregate ( River Sand) in concrete at 3 MTPA Integrated Steel Plant Project by TATA Steel Kalinganagar Odisha India. Accordingly Trial Mix design of M25 grade concrete was carried out using crushed stone dust after fulfilling the physical properties as per the relevant standard.

Coarse aggregate = subangular crushed stone Mix Design Example Coarse aggregate = subangular crushed stone Nominal maximum aggregate size = 3/4" Design strength = 4500 psi Specified slump = 12" Coarse Fine Aggregate Aggregate Unit weight (lb/ft3) = 101 106 Bulk specific gravity (dry) = Bulk specific gravity (SSD) =

In this study we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3 7 and 28 days respectively. The mix design has been done as per IS 10262. Advantages of mix design Mix design aims to achieve good quality concrete at site economically. I.

Crushed concrete has been in use since the ancient times only to be integrated with gravel sand and cement to ensure durability. The practice was first recorded in the 1860s. US construction companies were reluctant to use the technique at first since crushing cured concrete proved to be much more costintensive in terms of labor.

Since this sand can be crushed from hard granite rocks it can be readily available at the nearby place reducing the cost of transportation from the faroff river sand bed. The cost of construction can be controlled by the use of manufactured sand as an alternative material for construction. Design Mix Concrete ensures that for a good
