The results of a laboratory experimental programme aimed at establishing chemical and mineralogical characteristics of aggregate and its likely influence on concrete performance are reported in this paper. UV visible spectroscopy (UV-vis), X-ray fluorescence (ED-XRF) and X-ray diffraction (XRD) analyses were used for chemical and mineralogical characterisation, respectively. Surface morphology was determined by using scanning electron microscopy (SEM) instrument. It was observed that Malaysian white aggregate contains large amount of silt materials (about 9%). It also contains high amount of SiO 3 (62.5%) and K 2 O (6.94%) compared with other natural aggregates. The surface morphology analysis clearly revealed the existence of palygorskite and smectite materials in the studied aggregate.
