This paper presents a new type of lightweight composite materials--calcium silicate board (CSB) produced almost entirely by industrial waste. It possesses light bulk density (below 1100 kg/m3 and rather high strength (flexural strength over 8.0 MPa). Through the standard tests of carbonation, recycling of freezing-thawing, and drying-wetting, the board maintains nearly the same strength, meanwhile having advantages of noncombustibility, sound, and heat insulation. Several engineering application illustrations with satisfactory results and its relevant construction details are introduced. The raw materials as well as the main technological processes are described briefly. As the durability of glass fiber reinforcement in the board is a matter of concern, the relevant analysis based upon the experimental results are also given in this paper.
