    Abstract

    The pores, or voids, in concrete consist of pores in the hardened cement paste, entrained or entrapped air voids, and voids in the pieces of aggregate. The porosity of the aggregate is treated extensively elsewhere in this volume. Other void spaces such as honeycombing, which is the result of gross failure properly to consolidate the concrete, and bleeding channels and pockets, which result from excess water content or poor mix proportioning, are also important but are not treated in detail here, because they are the result of poor practice and are not inherent to properly prepared concrete.
