摘要：Loose coloured aggregates comprise hard mineral aggregates the particles ofwhich are coated with a mixture of a drying oil, a drier and colouring material. Aggregatesspecified are granite, limestone, marble, slate, gravel, felsite, pumice, shale, sandstoneand pudding stone. Drying oils specified are raw or boiled linseed oil and hempseed oil.Driers specified are terebine, manganese dioxide, red lead, lead acetate, litharge, Pariswhite and white lead. Other ingredients may be added, e.g. petrol as a volatile diluent,alum to enhance the colour effect, a non-drying oil if complete drying is not desired andcork to produce resiliency in the bound product. The Provisional Specification refers tocoloured lawn sand containing ammonium sulphate, sulphate of iron, potash andcarbonate of lime.ALSO:Loose coloured aggregates comprise hard mineral aggregatesthe particles of which are coated with a mixture of a drying oil, a drier and colouringmaterial. The coloured aggregate may be used loose as a surfacing material, e.g. forstucco work, or as coloured sand or it may be mixed with fertilizers, weedkillers &c. toproduce a lawn sand. The coloured aggregate may also be bound by a similar mixture ofdrying oil, drier and colouring material to which has been added a resinous material, e.g.rosin. Aggregates specified are granite, limestone, marble, slate, gravel, felsite, pumice,

shale, sandstone and pudding stone. Drying oils specified are raw or boiled linseed oiland hempseed oil. Driers specified are terebine, manganese dioxide, red lead, leadacetate, litharge, Paris white and white lead. Other ingredients may be added, e.g. petrolas a volatile diluent, alum to enhance the colour effect, a non-drying oil if completedrying is not desired and cork to produce resiliency in the bound product. According tothe Provisional Specification the aggregates need not be precoloured before beingmixed with the coloured binder and the aggregate may consist wholly of a powderedmineral so that a product resembling coloured asphalt is produced. The ProvisionalSpecification also refers to coloured lawn sand containing ammonium sulphate, sulphateof iron, potash and carbonate of lime.ALSO:Loose coloured aggregates comprising hardmineral aggregates the particles of which are coated with a mixture of a drying oil, a drier,and colouring material may be mixed with fertilizers, weed-killers, &c. to produce a lawnsand.
