Apr 22, 2015 Methods of Aggregate Sampling Due to the various sampling locations and the availability of equipment, there are several methods of taking aggregate samples. Uniformity of obtaining the sample cannot be emphasized enough, since it eliminates one variable in test results. The technician must remember that safety comes first. 1. PRODUCTION SAMPLING Bin Sample Sampling the

The hollow load bearing concrete blocks of the standard size 400 x 200 x 200 mm will weight between 17 and 26 kg 1063 to 1625 kgm3 when made with normal weight aggregates. normal weight blocks are made with cement, sand, gravel, crushed stone and air-cooled slag.
Such as impact, crushing and abrasion resistance be used to assess aggregate durability. the micro-deval abrasion test was developed in france during the 1960s. it is a wet ball mill test. a 1.5 kg graded aggregate sample retained on the 9.5 mm sieve, 2 l of water and a 5 kg
The size 4.75mm is a common fraction appearing both in coarse amp fine aggregate. these various sizes are usually divided by means of sieve analysis. sieve analysis is the operation of dividing a sample of aggregate into various fractions each consisting of particles of the same size.

Increases with an increase in coarse aggregate size. however, most other studies disagree. walker and bloem 1960 and bloem and gaynor 1963 concluded that an increase in aggregate size results in a decrease in the compressive strength of concrete. cook 1989 showed that, for compressive strengths in excess of 69 mpa 10,000 psi,
A dried sample shall be then weighed 5 kg preferably and sieved successively on sieves starting with 40mm and then through 4.75mm for 20 mm down an aggregate size and through 2.36 mm for 12.510 mm down an aggregate size.

Graphs were plotted for each sample of aggregate with gradation index n values on the x axis and density values on the y axis as shown in fig. 1. from these graphs, the optimum value of gradation index n-opt was determined corresponding to maximum density value for each sample of aggregate. the values of optimum gradation index n opt,
1 - take the sample of coarse aggregate using the sample splitter. 2 -sieve the sample with 4.75mm sieves and ignore the materials passing through no.4.75 sieve. - 3 - wash the sample to remove dust.. 4 - put the sample in the oven at 105 c.for 24hours. 5 - get the sample out of the oven, leave it to cool then determine its weight.
