It was found that the sand equivalent values are continuously decreasing from 84 to 14 in the fraction 02 mm and from 87 to 18 in the 04 mm fraction with increasing of the methylene blue

Jun 01 2016 There is no absolute value given in published standards that limits these values However results based on past research indicate that if the methylene blue value is below 1 gkg there is no negative effect on concrete strength a high sand equivalent value for fine aggregate indicates a positive effect on concrete properties

Quality Testing of Sand at The Construction Site for The Concrete There are different methods for testing the quality of sand at the construction site for concrete construction The quality of the sand is as important as other materials for concrete The most different which passes through the 475 mm IS strainer is known as the fine aggregate

to find the neutral axis of the equivalent concrete member we transform the width of the steel by multiplying by n to find the moment of inertia of the equivalent concrete member I or p and must be less than a value determined with a concrete strain of 0003 and tensile strain of

NOTE 4 Material passing the No 10 2 mm sieve shall have a sand equivalent of at least 28 for Group II aggregates Sand Equivalent values as low as 20 will be acceptable provided they are attributed exclusively to rock flour and the percent passing the No 10 2 mm sieve does not exceed 40 B Fabrication General Provisions 101 through 150

In this research the equivalent age concept was used in order to simulate strength development of heat treated sand concrete compared with ordinary concrete at different temperature 35 55 and 70 C and validate the simulation results with our experimental results Sand concrete is a concrete with a lower or without coarse aggregate dosage it is used to realize thin element as small

Apr 30 2011 So if your sample has a 90 sand equivalent that means that 90 of the sample was good material and 10 was detrimental If you have a 40 sand equivalent that means that 40 of the sample was good material and 60 was detrimental Many materials such as concrete sands will have high SEs in the 80s or 90s but it is very rare to see a 100 SE

The strength of the concrete greatly depends on the density of the concrete hence we should not play with the ratio of sand to aggregate I would suggest the ratio of 123 or 1153 for M20 grade concrete and 124 or 12535 for M15 grade concrete If you prepare concrete with your ration then the concrete will have too much sand

Recommend Rvalue testing be reduced to 1 every 10000 cu yd when test records demonstrate that material from the same source and having comparable grading and sand equivalent values meets the minimum Rvalue requirements

Some sources quote a much higher Rvalue for sand and gravel aggregate but you need to look at the thickness or amount of sand or gravel when you see such quots For example some cite sand and gravel aggregate as providing R 111 FOR 8 INCHES of thickness Thats equivalent to an Rvalue of R 01388 per inch but without considering moisture level

Table 4 shows density of concrete cubes ranging from 2441kgm to 2588kgm These values fall within the density values for normal weight concrete as stated by Neville 2000 It can be seen that the densities of the specimen increase with the days of curing which suggest that there is no deterioration of the said concrete
