Abstract
A substantially water-resistant resin-coated aggregate for use in concrete includes a porous aggregate body, such as an artificial light weight aggregate, with an elastic layer made of a phenol resin elastomer deposited on the aggregate body, a rigid phenol resin coated on the elastic covered aggregate body. This resin-coated aggregate has a high water absorption prevention and further an external stress-damping function.
