ABSTRACT:
New set-accelerating admixtures for hydraulic cement compositions are disclosed. These admixtures incorporate set-accelerating compounds and methylol derivatives of amino acids, are found to be surprisingly effective in decreasing the initial set time of hydraulic cements, mortars, and concretes, and are particularly advantageous in reduced-temperature set-accelerators.
