Experimental Study of Cement Mortar on Compressive Strength and Wave Velocity Characteristics for Different Sand/Cement Ratio and Particle Sizes

Abstract

Cement mortar is the most commonly used cement-based material, which widely used in construction materials, filling materials and other fields. The aim of this paper is to study the compressive strength and wave velocity characteristic in different particle sizes and sand/cement ratio. The uniaxial compressive strength test and wave velocity test were carried out in different particle size and sand content of mortar samples, respectively. It was found that the compressive strength and wave velocity decrease with the increase of sand/cement ratio. It is interesting that compressive strength and wave velocity in all specimens gradually increases with the increase of particles sizes. The compressive strength of cement mortar is related to the wave velocity. In detailed, the compressive strength and wave velocity was fit to linear relationship. It could thus be used to predict the compressive strength of cement mortar by wave velocity.
