MS has the characteristics of particle morphology, stone powder content and parent rock, resulting in some differences in the performance of MS and NS concrete [7].Nanthagopalan et al. [8] successfully prepared self-compacting concrete …
The natural river sand adhered to the finer gradation, characterized by a fineness modulus of 1.63, while the M-sand exhibits a coarser gradation, having a fineness modulus 2.74. The experimental results showed that the ECC mixtures with M-sand improved the compressive strength (up to 29 %) at 100 % replacement level and marginally influenced ...
3. What is the density of M Sand? The Fineness modulus of river sand is 5.24. Manufactured Sand: M-Sand was used as partial replacement of fine aggregate. The bulk density of Manufactured sand was 1.75 kg/m3, specific gravity and fineness modulus was found to be 2.73 and 4.66, respectively. 4. Why specific gravity test is done?
Two types of manufactured sand and one type of natural river sand were selected for the tests, and nine sets of concrete ratios were designed with three strength levels (C30, C40, and C50). ... the larger the fineness modulus of the sand, the smaller the crushing index, the better the particle grading, the stronger the ability to adsorb water ...

Dec 15, 2020 Fineness modulus of Sand is an index number that indicates the mean size of the sand particles It is knowing by performing the sieve analysis with standard IS sieves Fineness modulus of sand ranges from 22 to 32 To ...
Obtained from crushing parent rock (PR), manufactured sand (MS) is a fine aggregate with a particle size of < 4.75 mm and its preparation process [17] is shown in Fig. 1.Moreover, the characteristics of MS directly affect the workability and mechanical properties of the concrete [17], [18], [19].Studies have shown that high-quality MS and gravel separated from slurry shields, …
The fines content in MS produced by wet process is low, which leads to the unreasonable grading and the large fineness modulus of MS, resulting in the poor workability …
The data in Table 2 were measured applying the methods specified in the Chinese standards GB/T 14684–2011 [24] and JGJ 52–2006 [25].
