We offer a full line of concrete additives that can increase the sustainability of your next project, while making concrete stronger, less susceptible to cracks, more cost efficient, and easier to place and finish. Our experienced team of concrete specialists skillfully blend sophisticated combinations of chemical admixtures, fibers, supplementary cementitious materials and color pigments to support our customers\u2019 innovations in construction methods. We can reduce your carbon footprint while improving the quality, strength, durability and appearance of the finished concrete.<\/p>

Chemical additives can be added to concrete to provide greater plasticity, workability and earlier levels of strength than from normal concrete, or to maintain concrete quality in challenging weather conditions. Admixtures decrease the amount of cement needed to achieve a given strength specification, resulting in a reduction of the carbon footprint of the concrete. There are five distinct types of chemical admixtures that all increase the sustainability of your concrete:<\/p>

Chemical additives can be added to concrete to provide greater plasticity, workability and earlier levels of strength than from normal concrete or to maintain concrete quality in challenging weather conditions. There are five distinct types of chemical admixtures.<\/p>

  • Air entraining agents\u00a0are added during mixing to produce microscopic air bubbles in concrete which will increase resistance to freeze\u2014thaw cycles, improve workability, and reduce bleeding and segregation of concrete mixtures. Air entrainment is usually specified for outside concrete slabs and is not necessary for interior concrete.<\/span><\/li>
  • Water-reducing\u00a0chemicals are used for two separate purposes: to lower the water content which increase the strength; or to obtain higher slump using the same water content for pumping concrete or in hot weather. Mid-range water reducers tend to be more stable over a wider range of temperatures.<\/span><\/li>
  • Retarders\u00a0delay the initial set of concrete and are used primarily in hot weather.<\/span><\/li>
  • Accelerators\u00a0reduce the initial set time of concrete and are recommended in cold weather as well as fast track construction where early strength gain is critical.<\/span>\u00a0Calcium chloride\u00a0is the most common and least expensive accelerator for non-reinforced concrete.<\/span>\u00a0Non-chloride accelerators\u00a0are specified when corrosion is an issue or when placing concrete in sub-freezing conditions.<\/span><\/li>
  • Superplasticizers\u00a0or High Range Water Reducers are in a special class of water-reducers used to produce concrete for pumping concrete where high-strength is required, and congested steel reinforcement is present. Superplasticizers are the critical ingredient in self consolidating concrete (SCC) mixes.<\/span><\/li><\/ul><\/div><\/div>
