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.
