Abstract The aim of this paper is to determine the characteristics of lightweight insulating concrete using rice husk in the natural state or treated with a 5% lime solution. Reported in the paper are the compressive strength results and the cement contents in each one of the eleven mixes prepared by the substitution of sand and gravel with rice husk. The concretes studied might be defined as materials with hybrid characteristics between lightweight structural concretes and insulating concretes. Keywords: Lightweight concretes ; insulating concretes; rice husk; concrete aggregates; agricultural wastes; strength of materials; compressive strength; density; composite materials; concrete construction 谢谢 |
