ABSTRACT:
Improved Portland cement compositions are provided by the use of a combination of additives which increase plasticity and allow the use of less water. When the mixture is cured or set, the resultant concrete has higher compressive strength, higher flexural and shear strength, is believed to be markedly less susceptible to penetration by moisture or corrosive liquids, and have greater freeze-thaw stability. Such concrete is highly advantageous in thin paving sections such as bridge deck overlays, overpasses, elevated freeways and the like. The preferred additives are a latex of a styrene-butadiene containing polymer and a dispersing agent such as a polymerized naphthalene sulfonic acid or a salt thereof.
