Some limestone and dolomite, however, is too soft, absorptive or friable to yield high-quality aggregate. Chert and flint are silicate rocks that were precipitated in water by organisms such as sponges. These rocks may be crushed for aggregate, but they may cause adverse reactions such as cracking and scaling in cement concrete.
