A new methodology for determining particle density and absorption of lightweight, normal-weight and heavy weight aggregates in aqueous medium
HighlightsThe surface absorption causes doubts in determining particle density.The methodology used to obtain water absorption according to standard causes uncertainty.The new method of obtaining absorption is more accurate and less susceptible to handling.The pycnometer method (determined by mass) shows problems.The differential mass proposed solves the disadvantages caused by the pycnometer method.
AbstractSurface water absorption affects the value of the particle density obtained according to the UNE 1097-6. The aqueous medium absorption according to the standard poses problems as much in coarse fraction as in fine fraction. This new methodology is proposed in order to solve the problems observed in the current standard. The method is validated experimentally applying it to 5 different lightweight aggregates, 2 limestone normal-weight aggregates and a heavyweight aggregate. Different initial water contents and evolution of water absorption up to 28days were analyzed.
