Abstract

Abstract

The typical characteristics of the coral sands in Maldives are irregular shape and abundant micropores,with irregular opening pores on particle surfaces and closed pores in particle interior,which is very different from the quartz sands.Based on the analyses of the physical and chemistry characteristics,an effective method to measure the void ratio of the coral sands is proposed,and calculation has been done with the actual measurement.Besides,the application of the electrical density gauge in engineering practice has the benefits of increasing the data reliability and improving the work efficiency.
