Abstract

A method of formulating a portland cement composition having an accelerated setting time at a selected water-cement ratio, comprising the operation of mixing portland cement and an α-hydroxycarbonyl compound selected from the group consisting of hydroxyacetic acid and its sodium, potassium, lithium, zinc and triethanolamine salts; lactic acid and its sodium, potassium and calcium salts; 2-methyl-lactate sodium; dl-sodium mandelate; and mixtures thereof; the concentration of the α-hydroxycarbonyl compound relative to the cement being an accelerating concentration for such a water-cement ratio.
