Abstract
At the East of Thailand, a shortage of river sand for producing concrete has frequently occurred while the large amounts of quarry dusts are being produced as by-products of stone crushers in many stone quarries. Then, the quarry waste from 12 stone quarries (in Rayong and Chonburi province) was taken to investigate the engineering properties as fine aggregate for concrete. The properties - namely type of parent rock, specific gravity, water absorption, gradation, fineness modulus (F.M.), organic impurities level, powder content, plastic index and sand equivalent value - were examined. The results show that the parent rocks of the samples are limestone, granite and rhyolite. The specific gravity of samples were in the range of 2.61 - 2.77. The gap gradations are found in all samples and the F.M. values slightly exceed the limit of ASTM standard. Absorption of quarry dust is high (around 2%). Although the high powder contents are found in all samples, the powder in quarry waste is non-plastic and non-organic material. Therefore, gradation and absorption of quarry waste could be carefully considered or improved before using quarry waste as fine aggregate in concrete. © (2014) Trans Tech Publications, Switzerland.
