Calcium Silicate bricks. Despite the method of using steam under pressure to cure sand and lime being patented in England in 1886, much of the subsequent development and eventual use of calcium silicate bricks has prospered more in Europe than the UK. Notable uses of the brick in London include Battersea Power Station and the RIBA …

Ethyl silicate made the surface a bit darker than the control one (Fig. 12.c) and no external film-forming effects were detected as it was also reported by Franzoni et al. in coated bricks [48]. As regards sodium silicate, cracks, white dots, diffuse white patina and partial scaling were found again in control ceramic surfaces (Fig. 12.d).
