Chemical admixture for cementitious compositions |
| abstract |
A non-chloride powder admixture that, when added to concrete, substantially reduces the setting time for concrete and increases the strength of the concrete is provided. The powder admixture preferably comprises a calcium aluminate compound (e.g., SECAR 51) and a lithium carbonate compound. The calcium aluminate compound preferably has at least 51.7% alumina. In some embodiments, a surfactant may be added to the mixture of the calcium aluminate compound and the lithium carbonate compound. In some embodiments, the powder admixture may be blended with a cementitious material, such as fly ash or slag. Upon adding water to the admixture and cementitious material mixture, both the setting time of the mixture reduces and the strength of the mixture increases as compared to the setting time and strength of the cementitious material without the powder admixture. |
