Calcium silica hydrates, or CSH, are the key to cement's solidity. As they form, they combine, developing tight bonds that lend strength to the material. These connections have a surprising byproduct — they make cement incredibly porous. Within the spaces between the bonds of CSH, tiny pores develop — on the scale of 3 nanometers.
