Effect of particle characteristics stress on the mechanical properties of cement mortar with coral sand

摘要: Abstract The coral sand is widely used as a construction material in the world. mechanical behavior of cement mortar made by would be quite different from that Leighton Buzzard (LBS) due to inherent properties sand, such large void ratio, irregular shape and particle breakage. effect size on crushing stress influence are examined this study. A series single compression tests particles were carried out. results revealed characteristic for both LBS decreased with increasing sizes. exponent relationship between average was proposed. stresses wide range which varied 0.99 MPa 38.25 MPa 10.98 MPa 89.41 MPa LBS, respectively. uncertainly analyzed considered Gaussian distribution. probability density function strengths derived further verified experimental results. Finally, specimens five types distributions sands prepared tested investigate effects compressive strength specimen. An proposed could helpful concrete mix proportion design sands.
