THE MICROSTRUCTURE OF LYTAG AGGREGATE

Lightweight aggregates are well known for their porous and cellular structure but little is known of the size, distribution and nature of these pores. Porosity of the aggregate has a significant influence on the properties of the aggregate, mix design and on the properties of the fresh and hardened concrete made with such aggregates. This paper presents a detailed study of the pore structure of aggregates made from sintered pulverized fuel ash. The porosity of the aggregates is then related to the absorption characteristics of the aggregate and its bonding to cement matrix. (Author/TRRL)
