    摘要: A glass-fiber reinforced light-weight cementitious product having a density of less than 85 pounds per cubic foot, a high tensile strength and a high compressive strength, when cured, and hence, suitable for structural articles in which such properties are required. The product is formulated from a mixture in which the aggregate comprises substantially equal parts by weight of fly ash cenospheres and silica fume.
