EFFECT OF PARTICLE SIZE ON THE MECHANICAL

up of 1760μm particle size at 50% volume content yielded the maximum impact strength of 23.2Jm-2. It is concluded that decrease in particle sizes increases the tensile strength and flexural strength, but causes a scattered diagram in hardness strength. In impact test, the strength increases with increase in particle size.

Effect of Particle Size on the Properties of Cement Paste

Setting time, strength development and volume changes are affected by the water content of paste. As the mean particle size decreases, the paste workability-water content relationship should approach a minimum, based on the supposition that the particle size distribution of the cement is the only factor that affects paste workability.

Feb 07, 2017  According to Potyondy and Cundall , if the particle size is relatively small as compared to the size of the model, the scale effect is not significant for modeling rocks in compressive loading conditions. Reducing the size of the numerical model will thus not significantly affect the simulation results but can improve the computing efficiency.
