2007-6-1  Chemical composition of silica chosen for this test work is shown in Table 2.The main constituent of the sample was SiO 2 which was 99% whilst other elements was less than 1%. Massive size reduction was obtained in a very short grinding period where within 600 s the particle size was reduced to 5.56 μm as shown in Fig. 1.It also showed the relation between

Effect of Grinding on Physico-Mechanical Properties of ...

Grinding of micro-silica makes changes in the microstructure of its particles and compressive strength was considerably increased after grinding. The effect of grinding for 5% micro-silica added concrete on compressive strength increased to 14, 30 and 29% for 4, 6 and 8 h duration, respectively. There is a reverse trend for 10% micro-silica ...

Impact of mesoporous silica on the chemical degradation

Amorphous solid dispersions were obtained in a very short grinding time (15 min), as testified by DSC, PXRD and ESEM analyses. Samples ground at 15 ′ and 30 ′ showed the presence of the same degradation product, as was evident from UPLC, MS and NMR analyses. This short paper brings to light the tremendous lattice de-structuration ability of ...
