Abstract:The freezing and thawing resistance of 47 structural lightweight concretes containing seven lightweight aggregates and varying amounts of natural sand fines are re-ported. This paper is fourth in a series regarding the partial or complete replacement of lightweight fines with sand. The seven lightweight aggregate concretes and companion sand and gravel aggregate concrete were evaluated at nominal compressive strengths of 3000 and 5000 psi. The level of durability was generally raised when increasing amounts of sand fines were used in the 3000-psi concretes, All 5000-psi concretes were highly durable and the use of sand fines provided only minor improvements in this case.
