Title: Modal Determination of the Effect of Bond
Between Coarse Aggregate and Mortar on the
compressive Strength of Concrete
Author(s): Palle Nepper-Christensen and Tommy P. H. Nielsen
Publication: Journal Proceedings
Appears on pages(s): 69-73
Keywords: alkali-aggregate reactions; bond (paste to aggregate); cement pastes; coarse aggregates;compressive strength; glass aggregate;mortars (material) ; plain concrete.
Abstract:Summarizes a longer report describing an experimental investigation which compared compressive strength of concrete made with glass marbles as the coarse aggregate with the compressive strength of concrete in which the bond between mortar and glass marbles was raised by coating the marbles with a thin layer of soft plastic. It is concluded that coating reduces the compressive strength by up to 2.5 times, the strength reduction being almost proportional to the volumetric content of glass marbles in the concrete.
