摘要：

Fly ash-lime-phosphogypsum (FaL-G) hollow blocks are one of the best substitutes for conventional burnt clay hollow bricks or concrete hollow blocks in construction industry. FaL-G hollow blocks are light in weight and being hollow, impart thermal insulation to the buildings. In this paper, a study based on the results of an experimental investigation on FaL-G hollow blocks is presented. The compressive strength, water absorption and weight of FaL-G hollow blocks were determined. The durability of these blocks in terms of loss in compressive strength in sulfate environments is also presented in this paper. It is observed that FaL-G hollow blocks have sufficient strength for their use in general building construction. (C) 2002 Elsevier Science Ltd. All rights reserved.
